Description
Technical field
The utility model relates to loudspeaker fields, and in particular to a kind of vibration-transmitting plate.
Background technique
Why people can hear sound, be because vibration has been transmitted to ear by external ear ear canal by the vibration in air
Film passes through the auditory nerve for the vibratory drive people that ear-drum is formed.Using this principle, then there is bone-conduction speaker, bone
Conduction speaker at work, the auditory nerve of people is transmitted to by the skin, subcutaneous tissue and bone of people, to make one to hear
Sound.Under normal circumstances, only if it were not for middle external ear damages or clogs ear canal with hand, sound is directly passed the ear of people by bone
It leads and wants weak many compared with sound is by output power of the air transmitted into ear-drum, therefore limit answering for bone-conduction speaker
With.
Vibration-transmitting plate is component important in bone-conduction speaker, passes the vibration influential effect matter of bone-conduction speaker
Amount.The vibration-transmitting plate of the prior art, mostly solid laminated structure, hardness is big, causes length travel smaller, to limit bone biography
The stroke for leading loudspeaker constrains its output power.
Utility model content
In view of the above problems, the utility model provides a kind of vibration-transmitting plate, it can be used in bone-conduction speaker, to improve bone biography
Lead the acoustical quality of loudspeaker.
To achieve the above object, the utility model solves by the following technical programs:
A kind of vibration-transmitting plate, including sheet noumenon, the sheet noumenon include outer ring plate, are connected on the inside of the outer ring plate
N wave sheets, the middle ring plate being connected on the inside of the n wave sheets and the interior ring plate being connected on the inside of the middle ring plate, n
For the integer more than or equal to 3, the first connection sheet, the middle ring plate are respectively connected between each wave sheets and the middle ring plate
There are two the second connection sheet and a third connection sheets, the width of second connection sheet to be greater than for connection between the interior ring plate
The width of the third connection sheet.
Specifically, n is 4, the quantity of the wave sheets is 4, and the wave sheets are m type structure, and both ends are connected to institute
It states on the inside of outer ring plate, middle part is connect with first connection sheet.
Specifically, the outer ring plate, wave sheets, middle ring plate, interior ring plate, the first connection sheet, the second connection sheet, third connect
Piece cooperates jointly so that form multiple hollowed out areas in the sheet noumenon, the sum of all described hollowed out area areas with it is described
The area accounting of sheet noumenon is greater than 20%.
Specifically, the outer ring plate outer ledge is equipped with a resigning breach, the resigning breach is located at third company
Right above contact pin.
Specifically, being additionally provided with two mounting holes on the outer ring plate.
Specifically, the sheet noumenon with a thickness of 0.1mm.
The beneficial effects of the utility model are:
The vibration-transmitting plate of the utility model, can be used in bone-conduction speaker, by the way that outer ring plate, middle ring plate, interior ring plate is arranged
Three-decker can be classified and biography is cooperated to shake, while improve the elasticity of vibration-transmitting plate, can improve the resonance frequency of vibration-transmitting plate
Rate ensure that the reliability of sound quality.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of vibration-transmitting plate of the utility model.
Appended drawing reference are as follows: outer ring plate 1, resigning breach 11, mounting hole 12, wave sheets 2, middle ring plate 3, interior ring plate 4, first connect
Contact pin 5, the second connection sheet 6, third connection sheet 7, hollowed out area 8.
Specific embodiment
The utility model is described in further detail below with reference to embodiment and attached drawing, but the implementation of the utility model
Mode is without being limited thereto.
As shown in Figure 1:
A kind of vibration-transmitting plate, including sheet noumenon, sheet noumenon include outer ring plate 1, n wave for being connected to 1 inside of outer ring plate
Unrestrained piece 2, the middle ring plate 3 for being connected to 4 wave sheets, 2 inside and the interior ring plate 4 for being connected to middle 3 inside of ring plate, each wave sheets
The first connection sheet 5 is respectively connected between 2 and middle ring plate 3, between middle ring plate 3 and interior ring plate 4 connection there are two the second connection sheet 6 and
One third connection sheet 7 can be classified by the way that outer ring plate 1, middle ring plate 3,4 three-decker of interior ring plate is arranged and cooperate biography
Vibration, while the elasticity of vibration-transmitting plate is improved, the resonance frequency of vibration-transmitting plate can be improved, ensure that the reliability of sound quality；
The width of second connection sheet 6 is greater than the width of third connection sheet 7, when vibration-transmitting plate works, since vibration concentrates on partially
It shakes in the middle part of piece, increases the width of two the second connection sheets 6, can ensure that the stability of interior ring plate 4, meanwhile, in order to guarantee
The area of hollowed out area 8 is as big as possible, and under the premise of the stability, reduces the cost of metal material needed for forming, third
The width of connection sheet 7 need not increase.
Preferably, wave sheets 2 are m type structure, and both ends are connected to 1 inside of outer ring plate, and middle part and the first connection sheet 5 connect
It connects, the wave sheets 2 of m type structure extend the length of sheet material, increase the elastic force of vibration-transmitting plate, while making source of sound on vibration-transmitting plate
Bigger displacement is generated, so that it is more highly sensitive to realize bone conduction speaker.
Preferably, outer ring plate 1, wave sheets 2, middle ring plate 3, interior ring plate 4, the first connection sheet 5, the second connection sheet 6, third connect
Contact pin 7 cooperates jointly so that forming multiple hollowed out areas 8 in sheet noumenon, hollowed out area 8 can be connected to vibration-transmitting plate upper and lower
Air, so that the leakage sound of bone-conduction speaker is reduced, while the sensitivity in order to guarantee sound quality, all 8 areas of hollowed out area
The sum of be greater than 20% with the area accounting of sheet noumenon.
Preferably, 1 outer ledge of outer ring plate is equipped with a resigning breach 11, and resigning breach 11 is being located at third connection sheet 7 just
Top, resigning breach 11 are used to limit vibration-transmitting plate and are mounted in conduction speaker later in the movement of y direction, outer ring plate 1
It is additionally provided with two mounting holes 12, resigning breach 11 and two mounting holes 12 to be distributed in isosceles triangle, so that after vibration-transmitting plate installation
It is more stable.
Preferably, sheet noumenon with a thickness of 0.1mm.
