Description

Full-band high-tone-quality hearing aid with sound beam and sound tunnel

Technical Field

The invention relates to hearing aid equipment, in particular to a full-band high-sound-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

The hearing aid belongs to a small loudspeaker, and can enlarge the originally inaudible sound for the hearing-impaired person, and then the residual hearing of the hearing-impaired person is utilized to enable the sound to be transmitted to the brain auditory center of the hearing-impaired person, so that the user can feel the sound.

In general, a hearing aid is structured to include a microphone 1, an amplifier 2, a receiver 3 (also referred to as a receiver), a volume adjuster 4, a power supply 5, and a housing 6 (see fig. 1). The working principle of the hearing aid is that a sound signal is collected by a microphone 1, then converted into an electric signal, then the electric signal is amplified by an amplifier 2, and finally the amplified electric signal is converted into an original sound signal by a receiver 3 and transmitted to the ear of a person.

As shown in fig. 2 to 5, the conventional receiver 3 includes a diaphragm 7, and a coil 8 and a magnet 9 for driving the diaphragm 7 to vibrate. The diaphragm 7 is particularly important as a vibrating and sounding structure, and the structure thereof can also be as shown in fig. 6 and 7.

When the receiver 3 works, currents with different magnitudes are output by the amplifier 2, converted into sound waves through frequency waves, the output energy is improved through power pushing, the coil 8 vibrates under the action of a magnetic field, meanwhile, the action rod 10 is connected to the vibrating diaphragm 7 and drives the vibrating diaphragm 7 to vibrate, and then air is pushed through the vibration of the vibrating diaphragm 7, so that sound is produced.

The common problems with the receiver of a conventional hearing aid are: the receiver has an inherent resonant frequency during pronunciation, and after exceeding the certain range of resonant frequency region, the high pitch region can not be bright, and the low pitch region is muddy and mellow not enough, leads to the noise in the environmental sound also can amplify when the human sound is amplified, can't effectively restore true environmental sound, brings the puzzlement for hearing the barrier person. The reason for this is that the current receiver diaphragm cannot satisfy the good wide-band vibration from the high-pitch area to the low-pitch area, i.e. cannot adapt to the wide frequency variation resonance and vibration of the high-pitch area, the middle-pitch area and the low-pitch area at the same time. In summary, the receiver of the conventional hearing aid has an unreasonable structural design, which is not favorable for the diaphragm to perform good sound vibration from the high-pitched area to the low-pitched area.

Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.

In order to achieve the purpose, the invention adopts the technical scheme that:

a full-band high-sound-quality hearing aid with a sound beam and a sound tunnel comprises a microphone, an amplifier and a receiver, wherein the receiver comprises a vibrating diaphragm, a coil and a magnet, wherein the coil and the magnet are used for driving the vibrating diaphragm to vibrate; wherein:

The relevant content in the above technical solution is explained as follows:

1. in the above scheme, the first groove and the second groove are crossed and communicated with each other on the surface of the diaphragm, which is helpful for rapidly transmitting the vibration of the coil to the periphery of the diaphragm through the cross-shaped sound tunnel (i.e. the sound tunnel) formed by the grooves.

2. In the above scheme, the intersection point of the first groove and the second groove is located at the center of the diaphragm, so that the design can improve the tone quality and tone color of the diaphragm.

3. In the above scheme, a connection beam is arranged between two adjacent strip-shaped sound beam components, and the connection beam spans over the first groove and the second groove to form the sound beam assembly in a groined shape; and each connecting beam is positioned in the central area of the surface of the diaphragm. By means of the design, the central area of the diaphragm can be reinforced.

4. In the scheme, the vibrating diaphragm is divided into a peripheral high-sound area, a middle-sound area and a central low-sound area from a sound frequency range; the wall thickness of the diaphragm is gradually increased from outside to inside, the wall thickness of a low-sound area is larger than that of a middle-sound area, and the wall thickness of the middle-sound area is larger than that of a high-sound area; the sound beam assembly is located in a bass region of the diaphragm.

By the design, the thicker bass region is arranged close to the center, so that low-frequency vibration with lower frequency and larger amplitude can generate more muddy and mellow bass in the bass region of the vibrating diaphragm; through setting up thinner high pitch range in the position of keeping away from the center, can make the frequency higher, the less high-frequency vibration of amplitude send more penetrating, bright high pitch in the high pitch range of vibrating diaphragm, and then make the receiver of audiphone produce the restoring sound of high fidelity at full frequency channel.

5. In the above scheme, the thickness of the inner end of each strip-shaped sound beam component is greater than that of the outer end. By means of the design, the central area of the diaphragm can be reinforced.

7. In the above scheme, 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 arranged between the outer ends of the first groove and the second groove and the surface of the diaphragm.

The working principle and the advantages of the invention are as follows:

the invention relates to a full-band high-sound-quality hearing aid with a sound beam and a sound tunnel, which comprises a receiver, wherein the receiver comprises a vibrating diaphragm, at least one surface of the vibrating diaphragm is provided with a first groove and a second groove, the two grooves are crossed and communicated with each other, and the surface of the vibrating diaphragm is equally divided into four resonance areas; the center of the surface of the diaphragm on the same side with the two grooves is also provided with a sound beam assembly which comprises a plurality of strip-shaped sound beam components, and the strip-shaped sound beam components are arranged on two sides of the first groove and the second groove in pairs; the two grooves respectively form a sound tunnel on the surface of the vibrating diaphragm.

Compared with the prior art, the invention improves the diaphragm design of the existing hearing aid, particularly a receiver in the hearing aid, in order to solve the problem that the existing hearing aid cannot effectively restore real environment sound because the existing hearing aid cannot give consideration to high, medium and low sound regions. The concrete aspects are as follows: firstly, erecting a sound beam component on the surface of a vibrating diaphragm; secondly, a cross-shaped groove is formed in the surface of the vibrating diaphragm, so that a cross-shaped sound tunnel is formed on the surface of the vibrating diaphragm.

Aiming at the problem that the receiver of the existing hearing aid cannot effectively restore real environmental sounds, the design and the sound production mechanism of the receiver are deeply discussed and researched, and the main reason that the sound restoration of the existing receiver causes noise interference is found out to be caused by unreasonable design of the vibrating diaphragm. Accordingly, the inventor breaks through the constraint of the traditional receiver composition design, and provides an improved design scheme of the invention, which changes the diaphragm from the traditional free vibration mode to the current standard vibration mode, solves the problems that the high-pitch area of the receiver cannot be bright and the low-pitch area is not full and smooth from the vibration, resonance and sound production angles, improves the fidelity of the sound of each frequency range, reduces noise interference, amplifies the real voice, has the characteristic of high degree of environmental sound reduction, and has the advantages of prominent substantive characteristics and remarkable technical progress and obvious technical effect.

Due to the application of the technical scheme, compared with the existing hearing aid, the invention has the following advantages and effects:

1. the surface of the vibrating diaphragm is provided with the sound beam component, and because bass has large amplitude and low frequency relative to treble, bass resonance is concentrated in the central area of the vibrating diaphragm, treble resonance is concentrated in the peripheral area of the vibrating diaphragm, the strength of the central area of the vibrating diaphragm is enhanced, and the sound beam component plays an important role in improving the tone color and tone quality of a bass area. Because the thickness of the diaphragm is a thickness gradually-changing structure with thick central area and thin periphery, the strength of the central area of the diaphragm is enhanced, the thickness difference between the central area and the peripheral edge area of the diaphragm is relatively changed, and the diaphragm also has a beneficial effect on improving the tone color and tone quality of a high-pitch area.

2. The cross-shaped groove is formed in the surface of the vibrating diaphragm, the cross-shaped sound tunnel is actually formed in the surface of the vibrating diaphragm, and vibration is rapidly transmitted to the peripheral edge of the vibrating diaphragm through the cross-shaped sound tunnel (namely a sound tunnel), so that the cross-shaped groove plays a key role in improving the tone and the tone quality of a high-tone area.

3. According to the invention, through the design of the sound beam component and the cross-shaped groove, four resonance areas are equally divided on the vibrating diaphragm. When the receiver produces sound, the vibration of the coil is transmitted to each resonance area through the sound tunnel, and resonance and vibration are generated, so that the vibration string sound of the coil is amplified into the resonance sound of the vibrating diaphragm. Each resonance region can generate one sound wave quantity, and then adds one original sound wave quantity to obtain five sound wave quantities. The sound volume is the number of sound waves, and the sound volume directly influences the tone quality, the penetrating power and the sound volume of the receiver. Therefore, the design of the invention can obviously improve the tone colors of the high-tone area and the low-tone area, increase the penetrating power and the volume of the high-tone area and the low-tone area and improve the fidelity of the sound of each frequency band.

4. The sound beam component and the groove can be arranged on the upper surface of the vibrating diaphragm, can also be arranged on the lower surface of the vibrating diaphragm, and can also be arranged on the upper surface and the lower surface of the vibrating diaphragm simultaneously.

Referring to fig. 8 to 23, the full-band high-sound-quality hearing aid with the sound beam and the sound tunnel includes a microphone, an amplifier, and a receiver, where the receiver includes a diaphragm 11, and a coil and a magnet for driving the diaphragm 11 to vibrate.

A first groove 12 and a second groove 13 are arranged on the upper surface of the diaphragm 11, and 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.

The first groove 12 and the second groove 13 are crossed and communicated with each other on the upper surface of the diaphragm 11, which is helpful for rapidly transmitting the vibration of the coil to the periphery of the diaphragm 11 through a cross-shaped sound tunnel (i.e., a sound tunnel) formed by the grooves. The intersection point of the first groove 12 and the second groove 13 is located at the center of the diaphragm 11, so that the sound quality and the timbre of the diaphragm can be improved. And equally divides the upper surface of the diaphragm 11 into four resonance regions 14.

By providing 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 rapidly transmitted to the peripheral edge of the diaphragm 11 through the cross-shaped sound tunnel (i.e., a sound tunnel), which plays a key role in improving the timbre and sound quality of the high-pitched sound region. Meanwhile, by equally dividing the four resonance regions 14 on the diaphragm 11, the vibration can be transmitted to the four resonance regions 14 through the sound tunnel, and resonance is generated, so that the timbres of the high-tone region and the low-tone region can be obviously improved.

Through set up sound beam assembly 15 on the upper surface at vibrating diaphragm 11, because bass is big, the frequency is low relatively the high pitch amplitude, the bass sympathetic response is concentrated on the central zone of vibrating diaphragm 11, and the high pitch sympathetic response is concentrated on the peripheral edge region of vibrating diaphragm 11, strengthens vibrating diaphragm 11 central zone intensity, has played the important function to improving bass district tone color and tone quality. Because the thickness of the diaphragm 11 is a thickness-gradually-changing structure (i.e. a design with a thin outer part and a thick inner part) with a thick central area and thin periphery, the strength of the central area of the diaphragm 11 is enhanced, the thickness difference between the central area of the diaphragm 11 and the peripheral edge area is relatively changed, and the thickness-gradually-changing structure also has a beneficial effect on improving the tone color and the tone quality of a high-pitch area.

Preferably, as shown in fig. 12, 13, 20, and 21, the sound beam assembly 15 is formed by arranging a plurality of strip-shaped sound beam members 15a in a groined shape, a connection beam 15b between the strip-shaped sound beam members 15a is suspended in the air relative to the upper surface of the diaphragm 11, and each connection beam 15b corresponds to a central area of the upper surface of the diaphragm 11. Four connecting beams 15b form a reinforcing structure in the shape of a Chinese character kou, so that the bass region in the center of the vibrating diaphragm 11 can be further reinforced, and the tone quality of the bass region of the vibrating diaphragm 11 can be further improved.

Preferably, the diaphragm 11 is divided into a peripheral high-pitch region, a middle-pitch region and a central low-pitch region from a sounding frequency band; the wall thickness of the diaphragm 11 is gradually increased from outside to inside, the wall thickness of a low sound region is larger than that of a middle sound region, and the wall thickness of the middle sound region is larger than that of a high sound region; by means of the design, the thicker bass region is arranged close to the center, so that low-frequency vibration with lower frequency and larger amplitude can emit more muddy and smooth bass in the bass region of the vibrating diaphragm 11; through setting up thinner high pitch range in the position of keeping away from the center, can make the frequency higher, the less high-frequency vibration of amplitude send more penetrating, bright high pitch at the high pitch range of vibrating diaphragm 11, and then make the receiver of audiphone produce the restoring sound of high fidelity at full frequency channel. The beam assembly 15 is located in the bass region of the diaphragm 11, and can further increase the load of the middle region of the diaphragm 4.

Preferably, the thickness of the inner end of the bar-shaped sound beam member 15a is larger than that of the outer end. With this design, a further reinforcement of the central region of the diaphragm 11 can be achieved.

Preferably, the first groove 12 and the second groove 13 are both arc-shaped grooves, so that the thickness of the diaphragm 11 is reduced as much as possible, and resonance and vibration of the diaphragm 11 are prevented from being affected.

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 is more uniformly transmitted to the peripheral portion of the diaphragm 11.
