[technical field]

The present invention relates to electroacoustic conversion art more particularly to a kind of loudspeakers.

[background technique]

With the arrival of mobile internet era, the quantity of Intelligent mobile equipment constantly rises.And in numerous mobile devices Among, mobile phone is undoubtedly most common, most portable mobile terminal device.Currently, the function of mobile phone is extremely various, one of them is just The music function of high-quality, therefore, the loudspeaker for playing sound be widely applied Intelligent mobile equipment till now it In.

[summary of the invention]

The technical problem to be solved in the present invention is to provide a kind of pneumatic noises that can be effectively reduced in ante-chamber, can improve The loudspeaker of performance and sound quality.

In order to solve the above technical problems, the present invention provides a kind of loudspeaker, including frame, it is individually fixed in the frame Vibrational system and magnetic circuit system, the vibrational system include the vibrating diaphragm for being fixed on the frame, driving diaphragm oscillations hair The voice coil of sound, the vibrating diaphragm include top dome, and the top dome is multi-cellular structure along the both ends of direction of vibration.

Preferably, the material of the top dome is foaming metal.

Preferably, the top dome includes the first layer close to the voice coil, the second layer far from the voice coil and connection institute State the middle layer of first layer and the second layer, the material of the first layer and the second layer is foaming metal, the centre Layer is aluminium foil layer.

Preferably, the foaming metal is foaming aluminum or Foamed Nickel.

Preferably, the first layer include the first noumenon portion and along direction of vibration through the first noumenon portion multiple the One through-hole, the second layer include the second body part and run through multiple second through-holes of second body part along direction of vibration, The aperture of the first through hole is identical as the aperture of second through-hole, and each first through hole on direction of vibration with One second through-hole is oppositely arranged.

Preferably, multiple first through hole and multiple second through-holes are arranged in array, and first described in each column Spacing between through-hole is identical, and the spacing between the second through-hole described in each column is identical, the spacing between first through hole described in every row Identical, the spacing between the second through-hole described in every row is identical.
