Inside sound device, internal humidity is easily caused, aging circuit is caused, service life is influenceed.
In view of above-mentioned defect, the design people is actively subject to research and innovation, to found a kind of Microspeaker, makes
It is with more the value in industry.
Utility model content
In order to solve the above technical problems, the purpose of this utility model, which is to provide a kind of Microspeaker, can reduce vibration,
Tonequality is improved, increases moisture resistance, increases the service life.
The utility model proposes a kind of Microspeaker, including magnetic circuit system, vibrational system and house fixed described
The housing of magnetic circuit system and vibrational system, the vibrational system includes vibrating diaphragm and voice coil loudspeaker voice coil, and the magnetic circuit system formation houses described
The magnetic gap of voice coil loudspeaker voice coil, the vibrating diaphragm is fixed on the housing upper end, and the junction at the edge of the vibrating diaphragm and the housing is provided with
Damping washer, the voice coil loudspeaker voice coil is incorporated into the middle of the lower end of the vibrating diaphragm, and moistureproof cotton, the protection against the tide are pasted with the vibrating diaphragm inwall
Cotton is located at the top of the voice coil loudspeaker voice coil, and the bottom of the magnetic circuit system and surrounding are arranged with rubber shock-absorbing sleeve, the rubber shock-absorbing sleeve
Between the magnetic circuit system and the housing.
As further improvement of the utility model, the magnetic circuit system includes washer, magnet and the magnetic combined successively
Yoke, the rubber shock-absorbing sleeve is set in the yoke.
As further improvement of the utility model, the length that the vibrating diaphragm outwards smoothly extends in middle four sides of arching upward upwards
Cube shape.
As further improvement of the utility model, the damping washer is four and is distributed in the corner of the vibrating diaphragm
Place.
As further improvement of the utility model, housing upper end both sides are provided with inwardly horizontal-extending step surface,
The step surface is provided with posting, the posting and is fixed with drier.
As further improvement of the utility model, the step surface and posting are integrally formed with the housing.
By such scheme, the utility model at least has advantages below：The Microspeaker is reduced by damping washer
