The invention relates to the structures of devices for sound emission, more precisely, to designs of headphones.

Known construction of headphones, whose body is made of wood.

In the application JP 2011082840 «Device earphone, publication 21.04.2011, IPC H04R 1/10 the headset made of wood and is formed in the form of cups for a better sound.

In the application JP 2009135956 «Headset», publication 18.06.2009, IPC H04R 1/10 the headset has air chamber in the cylindrical part. The body is made of wood, for better sound and more simple fastening parts of the headset to the chassis.

Closest to the claimed invention is earpiece design by the patent 0363082 «Device earphone, publication 11.04.1990, IPC H04R 1/10 containing a pair of headphones, each of which contains a body. The body is made of wood and includes sound camera. On the chassis mounted speaker. On the back of the camera sound, opposite the loudspeaker formed irregular structure in the form of flutes, grooves, holes or ledges.

The technical result of the invention is to create a new design of the headset, allowing to obtain a characteristic sound closer to the original.

Device headset for audio playback, includes housing with internal sound of a camera mounted in the housing electro-acoustic transducer. The body is made of wood with wall thickness between the outer surface of the hull and the inner surface of the sound of the camera in the range from 5 mm up to 25 mm, and inner side surface of the sound of the camera includes a number of parallel grooves with stepped. The inner surface of the sound of the camera opposite the transducer is flat and approximately parallel to the plane of the location on the body of the radiating element referred to the Converter.

When you run the body part wooden, rather thickness, in which the side the surface of the sound of the camera includes stepped seizure, and the surface of the sound of the camera opposite the transducer is planar allows to receive qualitatively new sound headphones.

Complicated picture of the interaction of sound waves from the transmitter with housing headset is characterized by the simultaneous processes of reflection, absorption, scattering, diffraction of waves and convert sound waves into other spatial patterns. To describe these processes is extremely difficult. However, these processes affect the specifications of the headset, which in turn leads to the properties of the headset, which assesses the consumer.

The technical properties of the design of the headset works simultaneously a number of signs. On the one hand material, which is a good damping material, as has the appropriate inner natural structure, on the other hand, certain thickness of a wooden body of the headset. The tree is quite hard material, which at the same time absorbs, scatters and reflects sound waves, therefore, the choice of the thickness of the shell is essential.

An important role plays the shape of the sound of the camera and its internal surface. The side surface of the sound of the camera body is inclined surface of sound camera opposite the transducer is flat and approximately parallel to the plane of the location on the body of the radiating element referred to the Converter. Combination and location relative to each other these surfaces on the technical specifications of the headset is decisive, especially in the reflection, absorption and scattering of acoustic waves important role to create a sound characteristics earphone play roughly parallel located on the side the surface of a hollow. These notches are made in the tree and have a regular structure, however, they, due to their fibrous structure of the material, are not regular for high frequencies. This combination of regularity and irregularity of the notches on the side of the curved surface of a sound chamber, combined with the flat surface of the bottom of the camera generates the appropriate -frequency characteristic of headphones at high and mid-frequency sounds. Diffuse scattering of high-frequency oscillations prevents the creation of a spurious reflections and contributes to the creation of sound volume and «transparent» sound headset through minimum distortion spurious.

However, this design of the headphones is also characterized by extremely precise localization of the music scene over the works.

In the particular case of the headset is made of solid wood, which allows to avoid additional distortions possible due to the heterogeneity of the material.

As the array of wood, in particular, can be used beech, walnut, amaranth, oak, mahogany, maple, Karelian birch, oak, merbau, mahogany, Sapele, wenge.

Stepped recess may be in the form of closed on the perimeter of the lateral surface of the camera sound grooves.

In addition, stepped recess may be in the form of upward or a downward spiral, deployed along the perimeter of the lateral surface of the sound of the camera.

Stepped recess can contain from 3 to about 10 arranged in parallel rows.

In the particular case of the steps grooves can be placed approximately parallel to the plane of the location on the body of the radiating element referred to the Converter.

In another particular case of the plane steps notch is located at an angle and from the axis of symmetry of the body, in the angle range from 91° to 125 C.

The inner surface of the sound of the camera opposite the transducer may contain a number of cavities, the cavity may be in the form of holes.

The outer surface of the body part can be done about the spherical shape or roughly oval in shape.

Earphone, contains a pair of headphones connected device for fixation on the head and device supply signal to Converter, in which each ear includes housing with internal sound of a camera mounted in the housing electro-acoustic transducer. The headset is made of wood with wall thickness between the outer surface of the hull and the inner surface of the sound of the camera not less than 5 mm, but not more than 25 mm Inner side surface of the sound of the camera is made in the form of the inclined surface and contains a number of parallel bars step grooves, and the inner surface of sound camera opposite the transducer is flat and approximately parallel to the plane of the location on the body of the radiating element of the transducer.

The invention is illustrated by drawings.

Figure 1 shows a General view of the headset.

Figure 2 shows the internal earpiece design in context.

Figure 3 shows an incision in the body part of the spherical shape, Fig 4 shows the top view of a spherical body part with the slots in the form of a spiral.

Fig 5 Fig 6 shows the headset spherical shape, the Fig.5 the form at the top and 6 incision.

Figure 7 shows an example of executing the notches on the side of the sound of the camera body part.

Earpiece (1) includes a pair of headphones, 1, interconnected device 2 for fixation on the head of the user and the device supply signal to Converter (figures not shown). Each ear 1 (Figure 2) includes housing 3 with internal sound camera 4 and mounted in a casing electro-acoustic transducer 5. The body is made of solid wood with a wall thickness h between the outer surface of 14 housing 3 and the inner surface of 15 the sound of the camera 4 in the range from 5 mm up to 25 mm The choice of the thickness of the shell is dictated by the terms of the exceptions resonance at audio frequencies array of wood, as well as the design of the sound of the camera.

As the array of wood, in particular, can be used beech, walnut, amaranth, oak, mahogany, maple, Karelian birch, oak, merbau, mahogany, Sapele, wenge. These rocks are sufficiently dense and homogeneous in the sense of the sound characteristics. The choice of breeds of a tree depends on the design of the sound of the camera, and is also determined by aesthetic terms. The hull form 3 earphone 1 can be spherical (Figure 3, Figure 4), oval (Figure 2, Figure 5-6) or otherwise meets the condition in the shell thickness.

Inner side surface of the the sound of the camera 4 contains a number of parallel grooves with stepped 7 (Figure 2), and the internal surface of the 8 audio camera 4 opposite transducer 5 is flat and approximately parallel to the plane of the location on the housing 3 radiating element transducer 5.

Stepped recess 7 contain from 3 to about 10 arranged in parallel rows. For example, the number of rows can be 4 or 8. Stepped recess can be formed in the form of circles, ovals (Figure 5) or in the form of upward or downward spiral (Figure 4), situated along the perimeter of the lateral surface of the sound of the camera 4. Step height recess depth from 1.5 mm to 4 mm Steps grooves 7 are approximately parallel to the plane of the location on the housing 3 radiating element transducer 5. However, they can also be arranged at an angle to and from the axis of symmetry of the body, in the angle range from 90° to 125 C, as shown in Fig.7. The choice of the angle, under which are the steps of fill depends on the overall design of the headset, housing material and the value of the radiating element transducer 5. In particular, one of the best options involves angle and in the area of 115 degrees.

The surface of 8 sound chamber housing 3 4 can contain a number of cavities 10. These cavities 10 may be in the form of holes, located across the surface of 8 bottom 3, and provide a means of additional damping stray reflections.

Design works in the following way. During the radiation of sound, in particular, a musical work, which is characterized by the large dynamic range of the sound and the presence of a large number of overtones, it is very important to acoustic chamber 4, which is the most important element in the formation of the sound field, entering the auricle user headphones, not formed additional spurious harmonics, and, on the other hand, preserved all the necessary components emitted by the transducer 5 of the spectrum of the sound field. This task is solved all the components of the housing 1 earphone. Body material 1, form the inner surface of the sound of the camera 4, parallel spaced stepped recess 7.

The proposed earpiece design and construction of the housing earphone provide improved performance sound such complex acoustic devices, which are the headphones closed type. Improvement of characteristics of headphones was confirmed at the tests, in particular, by measuring their amplitude-frequency characteristics.
