Abstract
The utility model provides a piezoceramics piece oscillator. Piezoceramics piece oscillator includes that the metal casing places in and piezoceramics piece, weight and signal amplifier in the metal casing, the weight is pressed and is established the piezoceramics piece, piezoceramics piece warp signal amplifier respectively with the earphone spiral two the lead wire electric connection. The utility model provides a piezoceramics piece oscillator, its pickup body that can regard as the ear bone -conduction earphone uses, has the small and exquisite advantage such as simple and convenient of structure.
Description
Technical field
This utility model relates to earphone accessory field, particularly relates to a kind of piezoelectric ceramic piece oscillator.
Background technology
At present, the pickup body within existing ear osophone is generally high sensitivity electret microphone, high
Sensitivity electret microphone has the disadvantage that 1, restriction due to wiring board, and the integrated level of circuit is little；2、
Because mike is assembled by multiple material, their temperature expansion coefficient differs needs it is contemplated that weld
The too high material deformation caused of Shi Wendu；3 if it is desired that sensitivity improves, and needs higher bias to go to drive；
4, affected greatly by ambient humidity, light and temperature；5, size is relatively big, relatively costly；6, can not be waterproof.
Utility model content
The purpose of this utility model there are provided a kind of piezoelectric ceramic piece oscillator, and it can be as ear osophone
Pickup body use, there is the advantages such as compact structure is easy.
This utility model is achieved in that
A kind of piezoelectric ceramic piece oscillator, described piezoelectric ceramic piece oscillator includes metal shell and is built in described
Piezoelectric ceramic piece, weight and signal amplifier in metal shell, described weight pressure sets described piezoelectricity pottery
Ceramics, described piezoelectric ceramic piece is electrically connected with the two of earphone spiral lead-in wires respectively through described signal amplifier.
As the improvement of above-mentioned piezoelectric ceramic piece oscillator, described metal shell is rectangular case structure.
As the improvement of above-mentioned piezoelectric ceramic piece oscillator, described piezoelectric ceramic piece is stripe shape laminated structure.
As the improvement of above-mentioned piezoelectric ceramic piece oscillator, described weight is circular briquette structure.
The beneficial effects of the utility model are: the piezoelectric ceramic piece oscillator that this utility model provides, and it is by pressure
Electroceramics sheet can pick up the vibration of otica well, and carries out signal processing by signal amplifier, is allowed to
Can use as the pickup body of ear osophone, be arranged by the structure of weight and metal shell meanwhile,
Making this piezoelectric ceramic piece oscillator be encapsulated as into a device, not only structure becomes easy to be light and handy, and can avoid out
Now cause owing to piezoelectric ceramic piece is the most crisp falls damage problem, simultaneously because be to vibrate transaudient principle, and encapsulation
After this device can be fully achieved IP67 level dustproof and waterproof.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
As shown in Figures 1 and 2, the present embodiment provides a kind of piezoelectric ceramic piece oscillator 1, piezoelectric ceramic piece oscillator
1 includes metal shell 11 and the piezoelectric ceramic piece 12 being built in metal shell 11, weight 13 and letter
Number amplifier 14, weight 13 pressure sets piezoelectric ceramic piece 12, and piezoelectric ceramic piece 12 is through signal amplifier 14
Two lead-in wires with earphone spiral 2 are electrically connected with respectively.
Specifically, as shown in Figures 1 and 2, metal shell 11 is rectangular case structure, piezoelectric ceramics 12
For stripe shape laminated structure, weight 13 is circular briquette structure.Designed by rational structure, make this piezoelectricity
Potsherd oscillator 1 can preferably pick up the vibration of otica.
When this piezoelectric ceramic piece oscillator 1 uses as the pickup body of ear osophone, its operation principle such as Fig. 2
And shown in Fig. 3, worn the user of this ear osophone when speaking, the vibration in its ear is by its piezoelectricity
Piezoelectric ceramic piece 12 in potsherd oscillator 1 picks up after arriving through amplifying circuit (i.e. signal amplifier 14) place
Reason is transmitted further to main frame, just can reach the purpose of audio frequency input.
The piezoelectric ceramic piece oscillator that the present embodiment provides, it can pick up otica well by piezoelectric ceramic piece
Vibration, and carry out signal processing by signal amplifier, be allowed to make as the pickup body of ear osophone
With, meanwhile, arranged by the structure of weight and metal shell, make this piezoelectric ceramic piece oscillator be encapsulated as into
One device, not only structure becomes easy light and handy, and can avoid the occurrence of and cause owing to piezoelectric ceramic piece is the most crisp
Fall damage problem, simultaneously because be vibrate transaudient principle, after encapsulation this device can be fully achieved IP67 level prevent
Dirt is waterproof.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
