Embodiment Construction

[0017] Such as Figure 5 As shown, the present invention is installed in the suspension structure of the micro-speaker, and the suspension structure of the micro-speaker of the present invention includes a basin frame, a magnetic cover, a front cover, a magnetic circuit device, a voice coil and a diaphragm. The magnetic cover is assembled in the pot frame and is located at one end of the pot frame, and the front cover is connected with the other end of the pot frame. The magnetic circuit device is located in the pot frame, one end of the magnetic circuit device is supported on the magnetic cover, and the magnetic circuit device is composed of a magnetic steel and a pole piece fixed integrally with the magnetic steel. One end of the voice coil is wound around the other end of the magnetic circuit device. The first end surface of the diaphragm is fixedly connected with the other end of the voice coil, and the second end surface of the diaphragm 6 is connected with a picking blo...

Abstract

The invention belongs to the field of a miniaturized loudspeaker and specifically discloses a suspension type elastic diaphragm for a miniaturized loudspeaker. The suspension type elastic diaphragm comprises an annular support for installing on the end surface of a loudspeaker vibrating diaphragm, multiple elastic arms and a flexible plate. A suspension frame and an attachment frame are connected through at least two suspension arms; each elastic arm is distributed between the annular support and the flexible plate; one end of each elastic arm is connected with the inner side wall surface of the annular support; the other end of each elastic arm is connected with the outer side wall surface of the flexible plate; the inner wall of the flexible plate is provided with two flanges arranged to be opposite to each other; the annular support and the elastic arms are provided with conductive parts; the conductive parts extend to the flanges on two of the elastic arms; and the positions of the conductive parts on other elastic arms extend to the connection position of the elastic arms and the flexible plate. The suspension type elastic diaphragm has the following advantages: while transmission of electric signals is ensured, the phenomenon of a fracture caused by a voice coil can be avoided at the same time, and while the weight of a vibration system is reduced, unevenness caused by vibration can be prevented, such that product distortion is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of micro-speakers, in particular to a suspension type elastic diaphragm used for micro-speakers. Background technique [0002] With the development of mobile communication technology, mobile multimedia audio technology is also developed. Accordingly, micro speakers are also required to have high sound quality, high performance, and high fidelity. [0003] The loudspeaker belongs to the electro-acoustic transducer device. The electric energy makes the diaphragm vibrate through the electromagnetic effect, and the vibrating diaphragm resonates with the surrounding air to produce sound. For the magnetic circuit part of the current loudspeaker, in order to obtain a better bass effect, the magnet must be as large as possible, but a large magnet needs a large voice coil to cooperate. As far as electronic products are concerned, mobile phones and tablet computers are getting thinner and smaller, and the space left for assem...
