Description

A kind of osteoacusis loudspeaker of S types shell fragment

Technical field

The utility model is related to audio and propagates equipment technical field, more particularly to a kind of osteoacusis loudspeaker of S types shell fragment.

Background technology

Most of sound that we hear is due to that sound wave is formed through air, and sound wave is reached in cochlea by outer middle ear Ear, sound wave can also pass to cochlea by directly vibrating for skull, and earphone currently on the market is used loudspeaker plug Enter human body ear or make earmuff type, can so cause：First easily damages the ear-drum of human body ear；Second we using ear When earphone being directly plugged into human body ear during machine；Long-term wear can be such that hearing is just greatly reduced；3rd can not liberate us Ear.

Osteoacusis is that sound by skull is passed to inner ear, and bone nerve conduction oscillator is a kind of converter, can directly be changed Electronic signal is mechanical signal, and bone nerve conduction oscillator is the new world standard of audio area on the mobile apparatus, and it is provided Accurate wideband voice is exported to user, is ready to send a new audio, the establishment of bone nerve conduction oscillator passes through Vibration transmission sound rather than apply pressure to the air of surrounding, audio signal transmission is very clear so that the reaction of brain and Synchronous sound.

Requirement more and more higher of the people to sound now, the demand to sound is also each different, and it is brighter that someone wants high pitch, Someone wants bass and sunk, and existing osteoacusis leads to not the sound as conventional horn due to the structure and material characteristic of product Film is equally smoothed out, and common osteoacusis sensitivity is poor, it is impossible to realize the more demands of people.

Utility model content

The purpose of this utility model is and a kind of S types shell fragment for proposing in order to solve shortcoming present in prior art Osteoacusis loudspeaker.

To achieve these goals, the utility model employs following technical scheme：

A kind of osteoacusis loudspeaker of S types shell fragment, S types are made by the resonance shell fragment of osteoacusis, to reach the power of extension resonance Arm lengths, so as to improve the sensitivity of product in itself, reach the effect for improving volume and low frequency, to solve like product sensitivity Poor problem, it is ensured that product tonequality is to reach more preferable auditory effect；Specifically include magnetic circuit part, resonance shell fragment housing unit and voice coil loudspeaker voice coil Component；The Voice coil assemblies are installed in magnetic circuit part；The magnetic circuit part is fixed on below resonance shell fragment housing unit；

The magnetic circuit part is made up of a T-shaped iron and two magnet；The T-shaped iron both sides are provided with positioning step；The magnet Fit to form magnetic circuit with the positioning step of both sides respectively；The T-shaped iron is provided centrally with square post；

The resonance shell fragment housing unit includes S types resonance shell fragment, adhesive piece and spacer；The adhesive piece is fixed on S There is a rectangular type groove at type resonance shell fragment center, that is, shell fragment center of resonating, adhesive piece is positioned in groove, and ensure adhesive piece bottom Face is concordant with resonance shell fragment bottom surface；Described S types resonance its bending place of shell fragment is crossed laser spots solid welding with T-shaped Tie Tong and determined.

The Voice coil assemblies include voice coil loudspeaker voice coil；The voice coil loudspeaker voice coil is adhered on square post.

Preferably, gap is left between adhesive piece at the top of the T-shaped iron.

Compared with prior art, the beneficial effects of the utility model are：

The osteoacusis loudspeaker and microphone of hollow shell fragment of the present utility model, hollow is made by the resonance shell fragment of osteoacusis, To reach the torque arm length of extension resonance, so as to improve the sensitivity of product in itself, the effect for improving volume and low frequency is reached, with Solve the problems, such as like product poor sensitivity, it is ensured that product tonequality is to reach more preferable auditory effect.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.

Reference picture 1-3, a kind of osteoacusis loudspeaker of S types shell fragment, including magnetic circuit part, resonance shell fragment housing unit and voice coil loudspeaker voice coil group Part；The Voice coil assemblies are installed in magnetic circuit part；The magnetic circuit part is fixed on below resonance shell fragment housing unit；

The magnetic circuit part is made up of the T-shaped magnet 2 of iron 1 and two；The both sides of T-shaped iron 1 are provided with positioning step 6；Two Magnet 2 fits to form magnetic circuit with the positioning step 6 of both sides respectively；The T-shaped iron 1 is provided centrally with square post 7；

The resonance shell fragment housing unit includes S types resonance shell fragment 3 and adhesive piece 4；The adhesive piece 4 is fixed on S types and is total to Shake at the center groove location of shell fragment 3；The bending place 8 of the S types resonance shell fragment 3 is fixed with T-shaped iron 1 by laser spot welding.

The Voice coil assemblies include voice coil loudspeaker voice coil 5, and voice coil loudspeaker voice coil 5 is adhered on square post 7.

Gap is left between the top of T-shaped iron 1 and adhesive piece 4.

Two magnet 2 are respectively placed in the T-shaped both sides of iron 1 by the utility model, and are close to positioning step 6 and are placed, and then will Voice coil loudspeaker voice coil 5 is placed on the center square post 7 of T-shaped iron 1, and voice coil loudspeaker voice coil 5 is positioned, and is stamped glue and is fixed；Resonate shell fragment housing group Adhesive piece 4 is first placed on the center groove location of S types resonance shell fragment 3 by part, it is ensured that bottom surface is concordant, is entered by way of laser spot welding Row is fixed；Finally both sides of the inwall with T-shaped iron 1 in the way of laser spot welding after the resonance both sides bending of shell fragment 3 of S types are fixed, protected Demonstrate,prove the T-shaped top of iron 1 and leave gap with adhesive piece 4.

Because voice coil loudspeaker voice coil 5 is positioned in the magnetic field of magnetic circuit part, when the electric current that audio signal is produced passes through voice coil loudspeaker voice coil 5, the meeting of voice coil loudspeaker voice coil 5 Transformable magnetic field is produced because of the change of electric current, so as to produce interaction with the permanent-magnetic field that magnetic circuit part is produced, and is made Vibration is produced, so as to send the vibration of different frequency, the audio of sound generator is changed into mechanical oscillation, is passed through human body bone It is sent to auditory nervous system and is reduced to sound.

It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model Within enclosing.
