Below with reference to accompanying drawing preferred embodiment of the present utility model is described.

In conjunction with referring to Fig. 1-shown in Figure 3, be the embodiment one of the utility model loud speaker.

As shown in Figure 1, be the explosion structural representation of the loud speaker of the utility model embodiment, it comprises: the diaphragm of loudspeaker 1 and loud speaker body 2, the diaphragm of loudspeaker 1 is fastened on the loud speaker body 2.

In conjunction with referring to Fig. 2 and Fig. 3, be respectively the plan structure schematic diagram of utility model embodiment loud speaker after assembling and the sectional structure schematic diagram of C-C direction shown in Figure 2, wherein: the diaphragm of loudspeaker 1 comprises: first diaphragm 11 and second diaphragm, 12, the first diaphragms comprise circular top part 111 and by outward extending first edge part 112 of circular top part 111 peripheries.

Second diaphragm 12 comprises hollow-out parts 121 and by outward extending second edge part 122 of hollow-out parts 121 peripheries, wherein: first edge part 112 and second edge part, 122 enclosings form a cavity 3.

In the present embodiment, first diaphragm 11 and second diaphragm 12 are made as the monolithic membrane structure.This monolithic membrane is sandwich construction, for example, it can comprise for the bottom of strengthening low frequency, be located at the surface of described bottom, is used for guaranteeing the inhomogeneity complex metal layer of vibration, or is located at and is used for middle composite bed that compensates high frequency etc. between bottom and the described complex metal layer.

Be understandable that the number of plies and concrete function that monolithic membrane is set can be adjusted according to the functional need of reality.

The effect that is provided with cavity 3 is: set up second diaphragm 12 on the basis of first diaphragm 11, make the not flexible or distortion under the effect that produces external force because of vibration of two diaphragms, keep the subwoofer level of loud speaker; In addition, cavity 3 can be formed between two diaphragms, the subwoofer level of loud speaker can be further strengthened.

In addition, the loud speaker of this two diaphragms structure at the fastening formation cavity 3 of two diaphragms, has replaced the structure that traditional single diaphragm structure need arrange pattern or figure at diaphragm, makes the sound of the high pitch scope of loud speaker and generation more clear.

Preferably, first edge part 112 and second edge part 122 are made as raised structures in the form of a ring, and it is beneficial to two diaphragms 11,12 are fixed on the loud speaker body 2.In addition, the direction of first edge part 112 and second edge part, 122 projections is opposite, and its effect is to make the area of space of the cavity 3 of two diaphragms, 11,12 mutual assembling formation bigger, strengthens the subwoofer level of loud speaker.
