Description

Technical Field

[0001] The present invention relates to a hearing aid device, and in particular to a full-band high-quality hearing aid with a sound beam and a sound tunnel. The hearing aid includes a box type, a behind-the-ear type, an in-the-ear type, and the like. Background Art

[0002] Hearing aids are small loudspeakers that can amplify sounds that the hearing impaired cannot hear. They then use their residual hearing to send the sounds to the auditory center of their brain, allowing them to feel the sounds.

[0003] Generally, the structure of a hearing aid includes a microphone 1, an amplifier 2, a receiver 3 (also called a receiver), a volume adjuster 4, a power supply 5 and a housing 6 (see Figure 1 ). The working principle of the hearing aid is to collect the sound signal through the microphone 1, then convert it into an electrical signal, then amplify the electrical signal through the amplifier 2, and finally convert the amplified electrical signal into the original sound signal through the receiver 3 and transmit it to the human ear.

[0004] like Figures 2~5 As shown, the structure of the existing receiver 3 includes a diaphragm 7, a coil 8 and a magnet 9 for driving the diaphragm 7 to vibrate. Among them, the diaphragm 7 is a structure for vibrating and generating sound, and its role is particularly important. Its structure can also be as shown in Figure 6 , 7 shown.

[0005] When the receiver 3 is working, the currents of varying magnitude output by the amplifier 2 are converted into sound waves through frequency waves, and the output energy is increased by the power push. Under the action of the magnetic field, the coil 8 is vibrated. At the same time, the action rod 10 is connected to the diaphragm 7 and drives the diaphragm 7 to vibrate. The vibration of the diaphragm 7 then pushes the air, thereby making a sound.

[0006] The common problem with the receiver of traditional hearing aids is that the receiver has an inherent resonant frequency when making sounds. When the resonant frequency range is exceeded, the high pitch cannot be bright and the low pitch is not thick and round enough, which causes the noise in the ambient sound to be amplified while the human voice is amplified. It is impossible to effectively restore the real ambient sound, which brings trouble to the hearing-impaired. The main reason is that the current receiver diaphragm cannot meet the good broadband vibration from the high pitch to the low pitch, that is, it cannot adapt to the wide frequency change resonance and vibration of the high pitch, mid-range and low pitch at the same time. In summary, the structural design of the receiver of traditional hearing aids is unreasonable, which is not conducive to the diaphragm to exert good sound wave vibration from the high pitch to the low pitch.

[0007] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a subject to be studied and solved by the present invention. Summary of the invention

[0008] The object of the present invention is to provide a full-band high-quality hearing aid with a sound beam and a sound tunnel.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is:

[0010] A full-band high-quality hearing aid with a sound beam and a sound tunnel, comprising a microphone, an amplifier and a receiver, wherein the receiver comprises a diaphragm, and a coil and a magnet for driving the diaphragm to vibrate; wherein:

[0011] A first groove and a second groove are provided on at least one side surface of the diaphragm, the first groove and the second groove are cross-intersected and interpenetrated on the surface of the diaphragm, the intersection point is located at the center of the diaphragm, and the surface of the diaphragm is equally divided into four resonance areas;

[0012] The diaphragm is also provided with a sound beam assembly at the center of the same side surface where the first groove and the second groove are provided, and the sound beam assembly includes a plurality of strip-shaped sound beam components, and the strip-shaped sound beam components are arranged in pairs on both sides of the first groove and on both sides of the second groove;

[0013] The first groove and the second groove form sound tunnels on the surface of the diaphragm respectively.

[0014] The relevant contents in the above technical solution are explained as follows:

[0015] 1. In the above scheme, "the first groove and the second groove are cross-intersecting on the surface of the diaphragm and interpenetrating each other", which helps to quickly transmit the vibration of the coil to the surroundings of the diaphragm through the cross-shaped sound tunnel (i.e., the sound tunnel) formed by the grooves.

[0016] 2. In the above solution, the intersection of the first groove and the second groove is located at the center of the diaphragm, and this design can improve the sound quality and timbre of the diaphragm.

[0017] 3. In the above scheme, a connecting beam is provided between two adjacent strip-shaped sound beam components, and the connecting beam spans above the first groove and the second groove, forming the sound beam component in a tic-tac-toe shape; and each of the connecting beams is located in the central area of ​​the diaphragm surface. With this design, the central area of ​​the diaphragm can be strengthened.

[0018] 4. In the above scheme, the diaphragm is divided into a high-pitched area at the periphery, a mid-pitched area at the middle section, and a low-pitched area at the center from the sound emission band; wherein the wall thickness of the diaphragm gradually increases from the outside to the inside, the wall thickness of the low-pitched area is greater than that of the mid-pitched area, and the wall thickness of the mid-pitched area is greater than that of the high-pitched area; the sound beam assembly is located in the low-pitched area of ​​the diaphragm.

[0019] With this design, by setting the thicker bass area close to the center, the low-frequency vibration with lower frequency and larger amplitude can produce thicker and rounder bass in the bass area of ​​the diaphragm; by setting the thinner treble area away from the center, the high-frequency vibration with higher frequency and smaller amplitude can produce more transparent and bright treble in the treble area of ​​the diaphragm, thereby allowing the hearing aid receiver to produce high-fidelity restored sound in the full frequency band.

[0020] 5. In the above solution, the inner end thickness of the strip-shaped sound beam component is greater than the outer end thickness. With this design, the central area of ​​the diaphragm can be strengthened.

[0021] 6. In the above solution, the first groove and the second groove are both arc-shaped grooves, which can minimize the thickness change of the diaphragm and avoid affecting the resonance and vibration of the diaphragm.

[0022] 7. In the above solution, the lengths of the first groove and the second groove are both smaller than the horizontal width of the diaphragm, and smooth transition surfaces are provided between the outer ends of the first groove and the second groove and the surface of the diaphragm.

[0023] The working principle and advantages of the present invention are as follows:

[0024] The present invention discloses a full-band high-sound quality hearing aid with a sound beam and a sound tunnel, comprising a receiver, the receiver comprising a diaphragm, at least one surface of the diaphragm is provided with a first groove and a second groove, the two grooves are cross-shaped and mutually connected, and the surface of the diaphragm is equally divided into four resonance areas; the diaphragm is also provided with a sound beam assembly in the center of the same side surface where the two grooves are provided, comprising a plurality of strip-shaped sound beam components, the strip-shaped sound beam components are arranged in pairs on both sides of the first groove and the second groove; the two grooves respectively form sound tunnels on the surface of the diaphragm.

[0025] Compared with the prior art, in order to solve the problem that the existing hearing aid cannot take into account the high, medium and low frequency ranges and cannot effectively restore the real ambient sound, the present invention improves the existing hearing aid, especially the diaphragm design of the receiver in the hearing aid. Specifically, it is embodied in the following aspects: first, a sound beam assembly is set on the surface of the diaphragm; second, a cross-shaped groove is opened on the surface of the diaphragm, so as to form a cross-shaped sound tunnel on the surface of the diaphragm.

[0026] The present invention aims at the problem that the receiver of the existing hearing aid cannot effectively restore the real ambient sound, and conducts in-depth discussion and research on the design and sound generation mechanism of the receiver, and finds out that the main reason for the noise interference in the sound restoration of the existing receiver is due to the unreasonable design of the diaphragm. Based on this, the inventor broke the constraints of the previous receiver composition design and boldly proposed the improved design scheme of the present invention. This improved design scheme changes the diaphragm from the previous free vibration mode to the current standard vibration mode, and solves the problem that the high-pitched area of ​​the receiver is not bright and the bass area is not thick and round enough from the perspective of vibration, resonance, and sound generation, improves the fidelity of the sound in each frequency band, reduces noise interference, amplifies the real human voice, and has the characteristics of high degree of restoration of ambient sound. Practice has proved that the improved design scheme has outstanding substantive characteristics and significant technical progress, and has achieved obvious technical effects.

[0027] Due to the application of the above technical solution, the present invention has the following advantages and effects compared with the existing hearing aids:

[0028] 1. The present invention sets a sound beam assembly on the surface of the diaphragm. Since the bass has a larger amplitude and lower frequency than the treble, the bass resonance is concentrated in the central area of ​​the diaphragm, and the treble resonance is concentrated in the peripheral edge areas of the diaphragm. Strengthening the strength of the central area of ​​the diaphragm plays an important role in improving the timbre and sound quality of the bass area. Since the thickness of the diaphragm is a gradual thickness structure with thicker central area and thinner peripheral areas, the strength of the central area of ​​the diaphragm is strengthened, and the thickness difference between the central area of ​​the diaphragm and the peripheral edge areas is relatively changed, which can also play a beneficial role in improving the timbre and sound quality of the treble area.

[0029] 2. The present invention provides a cross-shaped groove on the surface of the diaphragm, which actually forms a cross-shaped sound tunnel on the surface of the diaphragm. Vibration is rapidly transmitted to the edges of the diaphragm through the cross-shaped sound tunnel (i.e., the sound tunnel), which plays a key role in improving the timbre and sound quality in the high-pitched area.

[0030] 3. The present invention divides the diaphragm into four equal resonance areas through the design of the sound beam assembly and the cross-shaped groove. When the receiver makes a sound, the vibration of the coil is transmitted to each resonance area through the sound tunnel, and resonance and vibration are generated, thereby amplifying the coil vibration string sound into the resonance sound of the diaphragm. Each resonance area can generate one sound wave amount, plus one original sound wave amount, a total of five sound waves. The sound wave amount is the number of sound waves, and the sound wave amount directly affects the timbre, penetration and volume of the receiver. Therefore, the design of the present invention can significantly improve the timbre of the treble and bass areas, increase the penetration and volume of the treble and bass areas, and improve the fidelity of the sound in each frequency band.

[0031] 4. The sound beam assembly and the groove of the present invention can be arranged on the upper surface of the diaphragm, can also be arranged on the lower surface of the diaphragm, and can also be arranged on both the upper and lower surfaces of the diaphragm.

[0062] The terms used in this document generally have the ordinary meaning of each term used in this field, in the context of the case and in the specific context, unless otherwise noted. Certain terms used to describe the present invention will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the present invention.

[0063] The terms "upper" and "lower" used in this article are directional terms. In this case, they are only used to illustrate the positional relationship between the structures, and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0064] See attached Figures 8 to 23 As shown, a full-band high-quality hearing aid with a sound beam and a sound tunnel includes a microphone, an amplifier and a receiver. The receiver includes a diaphragm 11, and a coil and a magnet for driving the diaphragm 11 to vibrate.

[0065] A first groove 12 and a second groove 13 are provided on the upper surface of the diaphragm 11 . The first groove 12 and the second groove 13 form a transverse sound tunnel and a longitudinal sound tunnel on the upper surface of the diaphragm 11 , respectively.

[0066] The first groove 12 and the second groove 13 are cross-shaped and interpenetrating on the upper surface of the diaphragm 11, which helps to quickly transmit the vibration of the coil to the surroundings of the diaphragm 11 through the cross-shaped sound tunnel (i.e., the sound tunnel) formed by the grooves. The intersection of the first groove 12 and the second groove 13 is located at the center of the diaphragm 11, and this design can improve the sound quality and timbre of the diaphragm. The upper surface of the diaphragm 11 is equally divided into four resonance areas 14.

[0067] By opening a cross-shaped groove on the upper surface of the diaphragm 11, the cross-shaped groove actually forms a cross-shaped sound tunnel on the surface of the diaphragm 11, and the vibration is quickly transmitted to the edges around the diaphragm 11 through the cross-shaped sound tunnel (i.e., the sound tunnel), which plays a key role in improving the timbre and sound quality of the high-pitched area. At the same time, by equally dividing the diaphragm 11 into four resonance areas 14, the vibration can be transmitted to the four resonance areas 14 through the sound tunnel and generate resonance, which can significantly improve the timbre of the high-pitched area and the low-pitched area.

[0068] A group of beam assemblies 15 are fixedly disposed on the upper surface of the diaphragm 11 . The beam assemblies 15 include a plurality of strip beam components 15 a . The strip beam components 15 a are arranged in pairs on both sides of the first groove 12 and on both sides of the second groove 13 .

[0069] By arranging the sound beam assembly 15 on the upper surface of the diaphragm 11, since the bass has a larger amplitude and lower frequency than the treble, the bass resonance is concentrated in the central area of ​​the diaphragm 11, and the treble resonance is concentrated in the peripheral edge areas of the diaphragm 11, thereby strengthening the strength of the central area of ​​the diaphragm 11, which plays an important role in improving the timbre and sound quality of the bass area. Since the thickness of the diaphragm 11 is a gradual thickness structure in which the central area is thick and the peripheral areas are thin (i.e., a design of thin outside and thick inside), the strength of the central area of ​​the diaphragm 11 is strengthened, and the thickness difference between the central area and the peripheral edge areas of the diaphragm 11 is relatively changed, which can also play a beneficial role in improving the timbre and sound quality of the treble area.

[0070] Preferably, Fig.12 , 13 As shown in Figures 20 and 21, the sound beam assembly 15 is composed of a plurality of strip-shaped sound beam components 15a arranged in a tic-tac-toe pattern, and the connecting beams 15b between the strip-shaped sound beam components 15a are suspended relative to the upper surface of the diaphragm 11, and each of the connecting beams 15b corresponds to the central area of ​​the upper surface of the diaphragm 11. The four connecting beams 15b form a "mouth"-shaped reinforcement structure, which can further strengthen the bass area in the center of the diaphragm 11, so as to further improve the sound quality of the bass area of ​​the diaphragm 11.

[0071] Preferably, the diaphragm 11 is divided into a high-pitched area at the periphery, a middle-pitched area at the middle section, and a low-pitched area at the center from the sound emission band; the wall thickness of the diaphragm 11 gradually increases from the outside to the inside, and the wall thickness of the low-pitched area is greater than that of the middle-pitched area, and the wall thickness of the middle-pitched area is greater than that of the high-pitched area; by this design, by setting the thicker low-pitched area close to the center, the low-frequency vibration with a lower frequency and a larger amplitude can emit a thicker and rounder bass in the low-pitched area of ​​the diaphragm 11; by setting the thinner high-pitched area far from the center, the high-frequency vibration with a higher frequency and a smaller amplitude can emit a more transparent and bright high-pitched sound in the high-pitched area of ​​the diaphragm 11, thereby making the receiver of the hearing aid produce high-fidelity restored sound in the full frequency band. The sound beam assembly 15 is located in the low-pitched area of ​​the diaphragm 11, which can further increase the load of the middle area of ​​the diaphragm 4.

[0072] Preferably, the inner end thickness of the strip-shaped sound beam member 15a is greater than the outer end thickness. With this design, the central area of ​​the diaphragm 11 can be further strengthened.

[0073] Preferably, both the first groove 12 and the second groove 13 are arc-shaped grooves, which can minimize the thickness change of the diaphragm 11 and avoid affecting the resonance and vibration of the diaphragm 11.

[0074] The lengths of the first groove 12 and the second groove 13 are both smaller than the horizontal width of the diaphragm 11 , and smooth transition surfaces are provided between the outer ends of the first groove 12 and the second groove 13 and the upper surface of the diaphragm 11 so that the vibration can be transmitted to the periphery of the diaphragm 11 more evenly.

[0075] The following is an explanation of other implementations and structural changes of the present invention:

[0076] 1. In the above embodiments, although the embodiments are given for the receiver of the behind-the-ear hearing aid, the present invention is not limited thereto, and may be other hearing aids such as box-type and in-the-ear hearing aids. This is easily understood and accepted by those skilled in the art.

[0077] 2. In the above embodiments, the number of the sound beam assemblies 15 is not limited to one group, and may also be multiple groups arranged in parallel or other designs that help to strengthen the load on the middle part of the diaphragm 11, which is easily understood and accepted by those skilled in the art.

[0078] 3. In the above embodiments, the beam assembly 15 and the two grooves 12 and 13 may be located on the upper surface of the diaphragm 11 (eg Fig. 9 , 13 , 17, 21), or may be located on the lower surface of the diaphragm 11 (as shown in Fig.10 , 14 , 18, 22), and can also be set on both the upper and lower surfaces of the diaphragm 11 (as shown in Fig.11 , 15 , 19, and 23).

[0079] 4. In the above embodiments, the strip-shaped sound beam members 15 a may be straight strips as shown in the figure, and are combined in pairs at 90 degrees and arranged in pairs on both sides of the first groove 12 and on both sides of the second groove 13 .

[0080] Alternatively, the strip-shaped sound beam component 15 a may also have an arc and include two straight sides, and the straight sides of two adjacent strip-shaped sound beam components 15 a are arranged in pairs on both sides of the first groove 12 and the second groove 13 .

[0081] 5. In the above embodiments, the first groove 12 and the second groove 13 are both arc-shaped grooves. However, the present invention is not limited thereto, and the grooves may be designed into other shapes, such as V-shaped, U-shaped, W-shaped and other concave structures. This is easily understood and accepted by those skilled in the art.

[0082] 6. In the above embodiments, the material of the diaphragm 11 can be metal, carbon fiber, paper, etc.

[0083] Compared with the prior art, in order to solve the problem that the existing hearing aid cannot take into account the high, medium and low frequency ranges and cannot effectively restore the real ambient sound, the present invention improves the existing hearing aid, especially the diaphragm design of the receiver in the hearing aid. Specifically, it is embodied in the following aspects: first, a sound beam assembly is set on the surface of the diaphragm; second, a cross-shaped groove is opened on the surface of the diaphragm, so as to form a cross-shaped sound tunnel on the surface of the diaphragm.

[0084] The present invention aims at the problem that the receiver of the existing hearing aid cannot effectively restore the real ambient sound, and conducts in-depth discussion and research on the design and sound generation mechanism of the receiver, and finds out that the main reason for the noise interference in the sound restoration of the existing receiver is due to the unreasonable design of the diaphragm. Based on this, the inventor broke the constraints of the previous receiver composition design and boldly proposed the improved design scheme of the present invention. This improved design scheme changes the diaphragm from the previous free vibration mode to the current standard vibration mode, and solves the problem that the high-pitched area of ​​the receiver is not bright and the bass area is not thick and round enough from the perspective of vibration, resonance, and sound generation, improves the fidelity of the sound in each frequency band, reduces noise interference, amplifies the real human voice, and has the characteristics of high degree of restoration of ambient sound. Practice has proved that the improved design scheme has outstanding substantive characteristics and significant technical progress, and has achieved obvious technical effects.

[0085] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
