【Specific embodiment】
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
In addition, as long as technical characteristic involved in the various embodiments of the present invention described below is each other not
Conflict is formed to can be combined with each other.
Active sound source or passive sound source generally include vibrating diaphragm, and vibrating diaphragm shakes to generate sound wave.Vibrating diaphragm is commonly exposed to such as sound
In the sound wave that the sound source of sound driver etc generates, and shake back and forth on the object traveling direction of plane where vibrating diaphragm
Dynamic, which then can generate and propagate additional sound wave.
Fig. 1 and Fig. 2 are referred to, show the schematic diagram of the passive vibrating diaphragm 100 in one embodiment of the invention.The passive vibrating diaphragm
100 be the compound vibrating diaphragm of pair of lamina, including：One by have both elasticity and rigid material made of casing play 10 and one by toughness material
Flexible glue layer 20 made of material.Wherein, passive vibrating diaphragm 100 is compounded to form by the casing play 10 and the flexible glue layer 20.Wherein, casing play
10 form a frame structure；Flexible glue layer 20 includes a border structure, the frame structure that the border structure is formed with casing play 10
Shape is consistent；Wherein, the border structure of the frame structure that casing play 10 is formed and flexible glue layer 20, which cooperates, to be fixed so that skeleton
Layer 10 accords with flexible glue layer 20, forms the passive vibrating diaphragm.
Specifically, the casing play 10 include inner ring 11, around the inner ring 11 outer shroud 12, extend from outer shroud first
Planar substrates 13 and connection inner ring 11 and the multiple arcs skeleton 14 of outer shroud 12.Arc skeleton 14 is based on the first planar substrates 13
It raises up.In this way, a clearance position is collectively formed in several arc skeletons 14 on the first planar substrates 13.And arc skeleton 14
The whole changing firmness requirements of the passive vibrating diaphragm 100 can be enhanced and ensure the stability of the passive vibrating diaphragm 100 so that vibration is more equal
Weighing apparatus.
Correspondingly, the shape of the shape of the flexible glue layer 20 and the casing play 10 is to consistent, including：Second planar substrates
21；And it raises up from the second planar substrates 21 and curved portion 22 corresponding with 14 position of arc skeleton.Curved portion 22 is
The border structure of the flexible glue layer 20.The house type portion 22 is placed in the clearance position of the arc skeleton 14 formation.
