Description
Technical field
It is especially that a kind of bone-conduction speaker product lets out sound suppression the utility model is related to bone-conduction speaker technical field
System processed.
Background technology
Mail topic is let out currently, existing in the bone-conduction speaker product of the prior art, this problem is always present in such production
In product development and application.The main problem for letting out mail topic is because bone-conduction speaker work, which generates vibration, can be transmitted to product shell
Body, and the application field of various products is different, product design and internal structure is different is more managed so that letting out not finding for sound
The scheme of property.
Utility model content
In view of the defect of the above-mentioned prior art, the purpose of this utility model is that：A kind of bone-conduction speaker product is provided
Sound suppression system is let out, conduct vibrations that bone-conduction speaker work generates can be alleviated to product shell.
The technical solution of the utility model is：Bone-conduction speaker product lets out sound suppression system, including shell and sets
Bone-conduction speaker inside the shell is set, the shell includes casing, is arranged in the cover board of cabinet top and setting in casing
The support plate of bottom, the casing is interior to be equipped with a fixed seat, and fixed seat is pressed at the top of support plate, and bone-conduction speaker is packed into admittedly
In reservation and it is clamped between fixed seat and cover board, is filled out between the fixed seat and casing and between fixed seat and support plate
Filled with vibration-damped component.
Further, the bottom end of the fixed seat has the salient point with support plate point contact.
Further, the fixed seat, cover board are flexible material；Flexible material is preferably rubber.
Further, vibration-damped component is to be sticked between fixed seat and casing gap between gap and fixed seat and support plate
Damping material；Damping material is preferably foam.
Sound suppression system is let out using bone-conduction speaker product provided by the utility model, advantage is：With soft
Property material clip handle bone-conduction speaker, be isolated again with damping material around bone-conduction speaker, to alleviate vibration pass
Lead product case.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
As shown in the figure：1-shell, 11-casings, 12-cover boards, 13-support plates, 2-bone-conduction speakers, 21-shake
Movable plate, 3-fixed seats, 31-salient points, 4-vibration-damped components.
Specific implementation mode
For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing
Unrestricted feature description is as follows：
As shown in Figure 1, bone-conduction speaker product lets out sound suppression system, including shell 1 is passed with the bone being arranged in shell 1
Lead loud speaker 2, shell 1 includes casing 11, be arranged 11 top of casing cover board 12 and support in 11 bottom of casing is set
Plate 13, casing 11 is interior to be equipped with a fixed seat 3, and fixed seat 3 is pressed in 13 top of support plate, and bone-conduction speaker 2 is packed into fixed seat 3
It is interior and be clamped between fixed seat 3 and cover board 12, between fixed seat 3 and casing 11 and between fixed seat 3 and support plate 13
Filled with vibration-damped component 4.
Fixed seat 3, cover board 12 are flexible material；Flexible material is preferably the materials such as rubber.
Vibration-damped component 4 is to be sticked between fixed seat 3 and casing 11 subtracting for gap between gap and fixed seat 3 and support plate 13
Shake material；Damping material is preferably the materials such as foam.
2 top of bone-conduction speaker is vibrating reed 21, and 12 bottom area of cover board is more than 21 top of vibrating reed and is connect with cover board 12
Tactile area.
The bottom end of fixed seat 3 has the salient point 31 with 13 point contact of support plate.So that being stayed between fixed seat 3 and support plate 13
Go out the space of damping material is installed.
Certainly, the shape of the bone-conduction speaker 2 of the application is unrestricted, and round, rectangular, oval or other shapes are equal
It can.
Specifically, (being played using 1KHz standard signal sources, export acoustic pressure 98dB) under same volume output condition, this reality
It is compared with the prior art that test result is as follows with novel：
1, damping material is filled between fixed seat 3 and support plate 13 and is not filled by damping material comparison, and leakage sound reduces 5-
7dB；
2, it is contacted and is compared using point contact knead dough, leakage sound reduces 2.5dB or so；
3, fixed seat 3 is compared using flexible material and using hard material, and leakage sound reduces 7dB or so；
4, cover board 12 is compared using flexible material and using hard material, and leakage sound reduces 25-26dB；
5, damping material is filled between fixed seat 3 and casing 11 and is not filled by damping material comparison, and leakage sound reduces 0.5-
1.5dB；
6, under same volume output, compared with the bone-conduction speaker product of sound hole leakproof sound processing is let out in other uses, leakage
Sound not only reduces 4.5-5.5dB, but also the sound quality exported is more preferable, and vibration sense is on the weak side, and wearing comfort is obviously improved.
2 product of bone-conduction speaker provided by the utility model lets out sound suppression system, and clamping bone with flexible material passes
Loud speaker 2 is led, is isolated again with damping material around bone-conduction speaker 2, to alleviate conduct vibrations to product case 11.
Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model
Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap
Within scope of patent protection contained in the utility model.
