Prior art

Despite the rapid development of communication technologies, the basic shape and construction of the telephone devices has not changed much over the last few decades. Although additional features, such as displays, buttons, special features and such additions were included in the base unit, the handset has retained its original shape, typically placed on top of the base unit along one side.

The conversation without lifting the handset by features Handsfree (loudspeaker) for some time now is the main property office and home phones. To support the functionality of the speakerphone to function without lifting the handset within a compact outline of the phone speaker speakerphone is usually placed under the body tube, which requires that the middle portion of the body tube was narrow and curved substantially in the direction opposite from the speaker in the base unit of the phone. This represents a significant limitation on the decisions of the industrial design. Tube rectangular, angular designs require a broader base unit and the speaker to work without lifting the tube from the tube. Other versions of traditional tube designs often lead to visual conflict with the industry is the principal design of the rest of the phone.

Detailed description of embodiment variants of the invention

As briefly described above, the acoustic passage in the form of one or multiple slits in the middle part of the tube can be used to provide improved acoustic performance for the of Ashoora without lifting the receiver of the base unit of the telephone and to provide flexibility in the design of the handset and the base unit. In the following detailed description referring to the accompanying drawings, which shows some illustrative embodiments of or examples. These aspects can be combined, other aspects can be implemented and structural changes may be made without going beyond the nature and scope of the present disclosure. Thus, further detailed description should not be construed in a restrictive sense, and the scope of embodiments is defined by the points of the applied formulas and cash equivalents.

While the options for implementation will be described in the General context of telephone equipment, including tubes and the base unit, the present disclosure is not limited to traditional telephone devices, and covers any communication device that may include a base unit and a handset, placed on top of the speaker base unit. Examples of devices with the use of modern communication technologies, where options for implementation may be implemented, are disclosed below.

The acoustic passage in the form of one or multiple slits in the tube can be designed manually or by using computer design programs. Such programs may involve hardware and/or software, such as software modules. Typically, software is mnie modules include routines, programs, components, data structures, and other types of structures that perform specific tasks or implement certain abstract data types. In addition, these auxiliary design tools can be used with other computer system configurations, including hand-held devices, microprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe and similar computing devices.

Figure 1 depicts the phone from the base unit and the handset, which includes an acoustic passage according to one variant of implementation. As discussed above, embodiments of may be implemented in communication devices, providing a variety of advanced communication technologies. Examples of such communication technologies include voice telephony, video telephony, instant messaging, data sharing, and similar technologies, but are not limited to. Thus, the communication device, providing these technologies may include elements such as, for example, display, special buttons, etc. that depend on secure communications technology (secured communication technologies).

Basic telephone, shown in figure 1, includes a base unit 112 and the tube 102. The tube 102 may be connected to the base unit 112 through the wire is s or wireless means. The wire 108 is an example of a wired connection. Many devices include a speaker 114 as part of a conversation without lifting the handset. In most designs of the speaker apparatus 114 is placed at one side of the device tube 102 when the handset is resting on the base unit 112. This presents two major difficulties: first, the audio quality of the call without lifting the handset is reduced due to the tube 102, lying on top of the speaker 114; secondly, the design of the tube 102 is limited by the need to contribute to the acoustic transmission from the speaker 114.

The tube 102 includes a microphone 106 at the bottom and a regular speaker 104 of the tube at the top. Normal earpiece tube 104 is designed to pass near the ear and the sound levels are substantially lower than those of the speaker 114. The tube 102, as shown in this figure, has a classic shape of the tube is preferred for speakerphones (device ' loud ' communication). The middle part of the tube is narrower than the bottom and top, and when placed on top of the base unit 112 middle part is elevated to allow you to provide superior acoustic transmission from the speaker 114 to have a conversation without lifting the handset.

Despite its classical form, the tube 102 includes a slot in the middle part, acting as an acoustic passage 110 to the speaker 114 for conversation be the lifting tube. Acoustic passage 110 can take a variety of forms - some examples are illustrated below for example rectangular, circular, elliptical, and so forth. The main task of the acoustic passage 110 is the provision of improved transmission of sound waves from the speaker 114 to have a conversation without lifting the handset when the handset is placed on top of the speaker on the base unit. It also leads to greater flexibility in the design of the tube, since the middle part of the tube 102 is no longer required to design as narrower than the upper and lower parts, or as a raised relative to the upper and lower parts.

Figure 2 depicts the top view of your phone 1 with the tube placed on top of the speaker of the speakerphone. How many home or office phones, speaker 114 to have a conversation without lifting the handset in the base unit 112 is placed under the tube 102 in the middle of the tube. However, unlike a standard phone, the handset 102 includes an acoustic passage 110, which allows the speaker 114 to transmit sound waves freely through the middle part of the tube.

The base unit 112 phone also includes additional elements, such as buttons 120 dual tone multi-frequency (DTMF) dialing buttons 118 special functions and the display 116. As discussed above, the communications device to implement the option is in the implementation, in addition to voice telephony, can provide other means of communication, such as instant messaging, video telephony, etc. Additional elements, such as, for example, the display 116 may facilitate other means of communication, as well as to complement the voice telephony (for example, to display the caller's number, date and time and similar information).

While some of the components and types of communication devices have been described above, they are intended only for illustration and do not impose restrictions on how the implementation. Many other types of hardware environments, components and devices can be used in the implementation of the acoustic passage in the tube according to the options exercise that uses the principles described here.

Figure 3 depicts a top view of another phone with a different placement of the tube, which includes an acoustic passage according to one variant of implementation. Although a typical telephony device, the tube is placed along the left or right side of the base unit (as shown in figure 1 or 2), the location of the tube 102, or other elements of the base unit 112 is not limited to these two places.

As shown in figure 3, the base unit 112 may include a display 116, a special button 118 and buttons 120 DTMF-dial at the bottom, while the speaker 114 to have a conversation without raised the I tube is placed in the upper part of the base unit. Thus, the tube 102 can be placed horizontally along the top side of the base unit 112 with an acoustic passage 110 on top of the speaker 114. Of course, many other offerings of the tube, the dynamics of conversation without lifting the handset, and other elements on the base unit is possible using the principles discussed here.

Figure 4 depicts a view in cross section of a standard tube on top of the base unit without acoustic passage. To simplify the elements, such as buttons, dials, and the lower part of the base unit 412, not shown in figure 4. The surface of the speaker to have a conversation without lifting the handset marked reference position 414.

As discussed earlier, the minimum value of the gap 426 is required above the surface 414 of the speaker to have a conversation without lifting the handset for audible transmission of sound waves, when the apparatus is in a mode without lifting the handset. Thus, the tube 402 must be designed with a curvature that allows the middle part 424 to rise relative to the lower and upper parts of the tube containing the microphone and speaker of the tube, respectively.

Not shown is another aspect of the standard tubes to increase the efficiency of the speaker to have a conversation without lifting the handset. Usually the middle portion 424 of the tube 402 is designed narrower than the upper and lower parts, in the plane perpendicular the first section plane, illustrated in the drawing. These limitations result in additional restrictions on handset and base blocks. For example, the elements as, for example, buttons or small screens related to advanced communication technologies, or even to the voice telephony, can when designing hardly be placed on the rear side of the tube due to limitations of the form.

In addition, the frequency band of the audio signal used in modern mobile devices, may be wider than traditional devices (e.g., broadband devices using the band 0-8 kHz, or narrowband devices using the band 0-4 kHz). Despite the measures discussed above, as a physical obstacle to transmission dynamics, the tube housing may reduce the sound quality from the speaker to have a conversation without lifting the handset. Reduced quality may depend on the used frequency band, tube shape and distance of the tube from the speaker.

Figure 5 depicts a view in cross section of a tube with an acoustic passage according to one variant of implementation, illustrating the flexibility provided by the acoustic passage. Two visible differences between the standard tube according to figure 4 and the tube according to figure 5 are the thickness of the tube and in the absence of empty space between the tube and the surface of the base unit in AP is Arata according to figure 5.

Acoustic passage 110 of the tube 502 figure 5 allows sound waves to be transmitted effectively from the speaker 114 to have a conversation without lifting the handset, effectively eliminating introducing tube obstacle to the speaker. This, in turn, eliminates the need to design the middle part of the tube 502 as narrower than the upper and lower parts, or screwloose for the formation of empty space between the middle of the tube 502 and the surface of the base unit 512. Thus, the surface of the tube and the base unit can come into contact with each other when the handset rests, as shown by the reference position 528.

Acoustic passage 110 of the tube 502 provides the use of any frequency band of the audio signal with high efficiency, regardless of the location of the tube. In addition, the removal of restrictions on the shape of the tube allows not only easier and more narrow construction of the tube, but that the appearance of the tube may be designed so that additional elements, such as buttons, dials, buttons, special functions, or even a small display can be placed on the rear side of the tube, which may be designed as a flat and wide according to some variants of implementation.

The shape, location, type of acoustic passage 110 and the material used is Amy for housing production tube 502, can still affect the quality of the sound from the speaker to have a conversation without lifting the handset. Thus, shape, location, type, and shape of the walls of the slot in the tube can be designed for optimal sound quality for a particular type of tubes (for example, the overall size and shape of the tube, the presence of additional elements on the tube and other features of the design). 6 and 7 depict examples of the forms of slots that can be used to implement embodiments.

6 depicts two examples of construction of the tube according to some variants of implementation. Tube 632-1 includes many of the slots 634 round shape as an acoustic passage for the speaker to have a conversation without lifting the handset. The number, shape and size of the slots 634 can be adjusted depending on the tube size, the size of the speaker, the frequency band of the audio signal dynamics, and other characteristics of the design. The shape of each slot can be not only round. In addition, the slits are not required to have a uniform shape. The shape and size of the slots may also vary on the same pipe, if you are an acoustic passage.

Tube 632-2 figure 6 has a one-piece cutout acoustic passage 636. The slot has a rectangular shape with rounded corners. Op is th same the size, shape (ratio of long side to short side) and the radius of the corners can be adjusted in order to facilitate optimum acoustic passage and the design of the tube. For example, the slot may have a round, elliptical, square or polygonal shape, which is more or less oblong, depending on the design of the tube and the size/shape dynamics to have a conversation without lifting the handset.

Fig.7 depicts two example designs tube according to other variants of implementation. As mentioned above, many slots can be used instead of one large slot for acoustic passage. The sample tube 732-1 includes four slots 738 rectangular shape with long sides along the short sides of the tube. Again, the size and shape of each slot can be defined in different ways depending on the design features. Tube 732-2 includes a rectangular slot 740 along the long sides of the tube.

Although the size, shape and type of slots have been discussed above, the slots acoustic passage are three-dimensional structures. Thus, the form of their third dimension, depth, may also affect the properties of the acoustic passage. A simple approach may be a straight wall, perpendicular to the plane ol the cramps. At the same time, other shapes and angles can also be implemented to improve the acoustic passage for the given form of slots, as illustrated in Fig and Fig.9.

Fig depicts side views of various examples of the slots according to the additional options for implementation. As mentioned above, the basic approach for the design of the slots acoustic passage may be straight inner wall 854, perpendicular to the plane 852 holes are slotted, as shown by the example of the slot 810-1. This leads to the rectangular form of the cross section along the third coordinate.

Another example of a wall of the slot includes a curved inner wall 858, which provides a larger hole on the side of the tube, far from the speaker (856) to have a conversation without lifting the handset, as shown by slot 810-2. Another example of the form is fully curved inner wall 864 between the lower and upper planes (861, 862) holes slotted, as shown by slot 810-3. The inner walls of the slits are not limited to symmetrical or identical views on all sides of the slot. Each inner wall of the slot may have a different shape or angle to the plane (the planes) holes.

Fig.9 depicts side views of two examples of sets of slits with different angles and shapes of the inner wall. As shown by the example of the slot 970-1, slots which may be designed with internal walls (974) at different angles to the planes (971, 972) holes. This can help to prevent the channeling effect of the transmitted sound waves. A similar effect can be achieved through the curved inner walls (978) with different angles to the planes (976, 977) holes, as depicted slits 970-2.

It should be noted that neither the shape and angles of the inner walls or the shape and size of the openings of the slits is not limited to the illustrated examples here. The slit acoustic passage according to the options of implementation can be realized in any form, angles and types using the principles described above.

Examples of embodiments can be designed and constructed in many different ways. These methods can be implemented in any way, including structures described in this document. For example, they can be realized by machine operations performed in Association with the software and hardware of any kind.

Another example of how they can be implemented, is that one or more of the individual operations of the method are performed in conjunction with one or more human operators performing some of them. These people-the operators are not required to be close to each other, each of them can only be close to the machine, which performs part of the program.
