Description

Hearing aid with annular integral sound beam

Technical Field

The utility model relates to a hearing aid equipment, concretely relates to audiphone of integral sound roof beam of belted ring shape. 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.

Referring to fig. 8 to 15, a hearing aid with an annular integral sound beam 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.

The upper surface of the vibrating diaphragm 11 is provided with a bridge-type sound beam 15, and the bridge-type sound beam 15 is annularly arranged at the horizontal center of the vibrating diaphragm 11.

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 bridge beam 15 is located in the bass region of the diaphragm 11, and can further increase the load of the middle region of the diaphragm 11.

Through set up bridge type sound roof beam 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 important effect 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.

The upper surface of the vibrating diaphragm 11 is further provided with at least two grooves 12, and the grooves 12 are radially arranged by taking the center of the vibrating diaphragm 11 in the horizontal direction as a reference, so that the surface of the vibrating diaphragm 11 positioned on the outer side of the bridge-type sound beam 15 is equally divided into a plurality of resonance areas 14; each groove 12 horizontally crosses the bridge-type sound beam 15, and is perpendicular to the bridge-type sound beam 15 in the longitudinal direction of the groove 12.

The groove 12 is concavely formed on the upper surface of the diaphragm 11 to form a sound tunnel.

By providing the radial groove on the upper surface of the diaphragm 11, the radial groove actually forms a radial 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 radial sound tunnel (i.e., a sound tunnel), which plays a key role in improving the tone color and tone 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.

The bottom of the bridge-type sound beam 15 is provided with a bridge opening 13, the bridge opening 13 is arranged in the width direction of the bridge-type sound beam 15 in a penetrating manner, and the lower opening of the bridge opening 13 corresponds to the groove 12. The sound beam is designed into a bridge type sound beam 15 structure, and particularly, a bridge opening 13 (a gap) is designed at one side of the sound beam, so that the bridge type sound beam 15 is like a bridge arch structure. When such a bridge-type sound beam 15 is erected on the sound tunnel, it is more favorable for transmitting vibration through the sound tunnel, so as to be more favorable for resonance and rapid vibration response of the diaphragm 11.

Preferably, when the diaphragm 11 is horizontal, a center line of the bridge sound beam 15 in the up-down direction overlaps with a center line of the diaphragm 11 in the up-down direction.

Each groove 12 is an arc-shaped groove, 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 influenced. Wherein, a smooth transition surface is provided between the outer end of the groove 12 and the upper surface of the diaphragm 11, so that the vibration is transmitted to the peripheral part of the diaphragm 11 more uniformly.
