The outer wall of the tangent plane 246 in the end of cambered surface 245, the semicircle cambered surface 245 and the vibration gum cover abuts against.Specifically,
Semicircle cambered surface and the outer wall of vibrationproof gum cover 23 on the inner wall of the protective shell 24 abut against, and limit vibrationproof gum cover 23 and are protecting
Shaking in protective case 24 positions motor 21 and vibrationproof gum cover 23.Protective shell 24 is additionally provided with tangent with semicircle cambered surface 245
Plane 246, being provided with for the structure are installed on conducive to motor 21 and vibrationproof gum cover 23 in protective shell 24.
In the present embodiment, prolong towards 246 direction of the plane as shown in fig.4, the outer wall of the vibrationproof gum cover 23 is equipped with
The boss 231 stretched and abutted against with the plane 246.Specifically, boss 231 and the plane 246 of protective shell 24 abut against, favorably
In making vibrationproof gum cover 23 not carry out radial rotating in the protective shell 24 effect of earthen platform abutted against by plane 246,
Limit the radial rotating of vibrationproof gum cover 23.
In the present embodiment, as shown in fig.1, length of the boss 231 along the direction of 21 output shaft of the motor is less than
The length of the vibrationproof gum cover 23.Specifically, installation and the institute of this kind of structure being provided with conducive to motor 21 and vibrationproof gum cover 23
In the installation cavity for stating protective case, and in axial direction, there is gaps between vibrationproof gum cover 23 and protective case, reduce and contact between the two
Area can subtract at least part of vibration and transmit, meanwhile, for vibrationproof gum cover 23 when absorbing vibration, there are certain for vibration gum cover
Vibration gap, rather than the own absorption of material one's very own, back towards outer transmission partial vibration energy, can increase anti-vibration rubber
The service life of set 23, and it is good to obtain vibration-isolating effect.
In the present embodiment, as shown in fig.4, the outer wall of the protective case is equipped with the fixation for fixing the protective case
Ear 247.Specifically, fixed ear 247 is mainly used for protective case being fixed in the inside of headset body 10, and protective case is fixed on ear
In a manner of mode on machine ontology 10 can be connected by screw, be bolted, be bonded etc..It can also be by the inside of headset body 10
Inner wall identical with 24 shape of protective shell is offered to be abutted protective shell 24 is fixed.
Further, protective shell 24 is being equipped with the card for being clamped with 10 phase of headset body on the end face of vibrating mass 22
Socket part (not shown).
A kind of hanging-on-neck type earphone, including above-mentioned protective device 20 are additionally provided in the utility model embodiment.
Hanging-on-neck type earphone in the utility model embodiment, as shown in fig.2, due to the use of above-mentioned protective device 20,
So that the motor 21 in hanging-on-neck type earphone will not cause the stuck of motor 21 because of the vibration of itself of motor 21, horse does not also occur
Up to 21 and the movement of vibrating mass 22, lead to vibration module failure, so that earphone failure, the service life of shortening earphone, on
The protective device 20 stated is simple in structure, can be easily mounted in the hanging-on-neck type earphone of the utility model, will not increase hanging-on-neck type ear
The cost of machine improves cost performance.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
