Embodiment 1

[0029] Such as figure 1 , figure 2 , image 3 Shown is one of the embodiments of the present invention. In this embodiment, the loudspeaker provided with a spring balance structure includes a single body, a casing 1 is arranged in the single body, a voice coil is arranged in the casing 1, and a The diaphragm, the middle part of the diaphragm is covered with Dome4, and several springs 2 are connected between the casing 1 and the Dome4.

[0030] Such as figure 1 The shown monomer is rectangular, and there are four springs 2, which are respectively arranged at the four corners of the rectangle. That is, it can play a role of vibration balance.

[0031] If the monomer is circular, at least 3 springs 2 are provided, which are evenly distributed between the shell 1 and the Dome 4, which can play a role of vibration balance.

[0032] Such as figure 2 As shown, as an optimized design, two springs 2 can form circuit leads, and then respectively connect wiring 5, and wiring 5 is...

Embodiment 2

[0038] In the second embodiment of the present invention, the Dome is arranged on the lower surface of the diaphragm body, and the spring constitutes the pulling structure of the vibration assembly, which can also play a role of vibration balance (this structure is not shown).

Abstract

The invention discloses a loudspeaker provided with a vibration balance structure. The loudspeaker provided with the vibration balance structure includes a body inside provided with a shell. A sound coil is arranged in the shell. A vibrating diaphragm is arranged above the sound coil. A Dome covers the middle part of the vibrating diaphragm. A plurality of springs are connected between the shell and the Dome. Two of the springs are circuit leads and are connected with wires respectively. The wires are connected with the sound coil and provide alternating current for the sound coil. According to the invention, a spring balance structure is arranged for the vibration assembly in the body, so that the structural stability of the vibration assembly is improved and polarization is reduced. While playing a supporting and fixing role, the two springs lead current into the sound coil, achieving a circuit connection effect, so that quality problems that may easily be caused by suspension leads in large vibration amplitude can be avoided and the acoustic performance of the loudspeaker can be improved.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a monomer in the loudspeaker. Background technique [0002] With the rapid upgrading of micro speakers, the performance requirements are getting higher and higher, and high sensitivity and low distortion have become the mainstream pursuit goals. In the monomer of the speaker, the diaphragm is the sound-generating device. The magnet cooperates with the voice coil to drive the diaphragm to vibrate up and down, and the speaker can only produce sound by vibrating the diaphragm up and down. For example, the Chinese invention patent "A Loudspeaker Structure" (Application No.: 201410670050.0) discloses a loudspeaker unit with a diaphragm above the voice coil, a Dome covering the middle of the diaphragm, and two leads connected to the voice coil. Chinese Utility Model Patent "A Loudspeaker Device" (Application No.: 201420646044.7) discloses a loudspeaker unit with a diaphragm above the voice coil, a com...
