Embodiment one:
As depicted in figs. 1 and 2, the utility model provides a kind of vibrating diaphragm 21, including center inner ring film 201 and flexible outstanding side
213, center inner ring film 201 includes top dome portion 211 and transition part 212 made of biomembrane, and transition part 212 is connected to top dome portion
211 outer peripheral edge, the outer peripheral edge of transition part 212 towards and the direction of 211 protrusion of top dome portion extend and to the side far from top dome portion 211
To gradually spreading, the outstanding side 213 of flexibility is adhered to the outer peripheral edge of transition part 212.
The vibrating diaphragm 21 of the utility model embodiment is made of center inner ring film 201 and flexible outstanding side 213, is two-part
Composite diaphragm structure；Wherein, center inner ring film 201 is divided into top dome portion 211 and transition part 212, and top dome portion 211 and transition again
Portion 212 is all made of biological membrane material and is made, i.e. the principal vibration part of vibrating diaphragm 21 is made of biological membrane material, biological membrane material tool
Have biggish internally-damped, when vibration can damp noise wave removing, accelerate vibration vibration of membrane and stop speed, the dynamic range of sound
Wider, elastic to act freely, so that vibrating diaphragm and loudspeaker have more overtones and better instantaneous property, user is to sound
Perception is more abundant, telepresenc is stronger.
In the present embodiment, biomembrane is preferably by blended, linen-cotton, fabric, fur, carbon fiber, glass, paper pulp and artificial training
One or more of Fiber Materials of plant are made.Above-mentioned material is that production membrane structure is commonly used in daily life
Material has good damping system using the biofilm structure that it is fabricated to, and the vibrating diaphragm 21 being fabricated to can have biggish
Internally-damped, when vibration, can damp noise wave removing, and the vibration for accelerating vibrating diaphragm 21 stops speed, the dynamic range of sound is wider,
Elasticity acts freely；And above-mentioned material selection range is wide, advantage of lower cost, on the basis of promoting loudspeaker tonequality, also
It can reduce cost of manufacture.
In the present embodiment, top dome portion 211 is made with transition part 212 of the biomembrane of same material or unlike material, i.e.,
Top dome portion 211 and the material of transition part 212 can be the same or different, as long as meeting both for the material of biological film character
?.
In the present embodiment, transition part 212 and top dome portion 211, which are integrally formed, makes, alternatively, transition part 212 and top dome portion
211 bonding connections.When top dome portion 211 and transition part 212 are made of same material, top dome portion 211 and transition part 212 are preferably adopted
With integrated molding, i.e., preferably using integral forming process production molding, manufacture craft is simple for top dome portion 211 and transition part 212, and
And it can guarantee the connective stability of the two intermediate location.
In the present embodiment, as depicted in figs. 1 and 2, transition part 212 includes cyclic annular flat sections 2121 and horn-like cone section
2122, cyclic annular flat sections 2121 are connect with the outer peripheral edge in top dome portion 211, cyclic annular flat sections 2121 by top dome portion 211 outer peripheral edge
Horizontally extending formation, horn-like cone section 2122 is from the outer peripheral edge of cyclic annular flat sections 2121 to the protrusion side in top dome portion 211
It is gradually diffuseed to form to fold and to the direction far from top dome portion 211.I.e. the vibrating diaphragm 21 of the present embodiment is in including middle part protrusion
The top dome portion 211 of semi-spherical shape, the periphery in the hemispheric top dome portion 211 is horizontally extending to form ring-type in a curved state
Flat sections 2121, protrusion direction of the periphery continuation of cyclic annular flat sections 2121 towards top dome portion 211, which turns down and deviate from top dome portion 211, prolongs
Stretch the horn-like cone section 2122 to form flare shape.
Specifically, as shown in Fig. 2, working as vibrating diaphragm due to the hemispherical dome structure that its top dome portion 211 is center position outwardly convex
