Problems solved by technology

For the existing loudspeaker unit, the front acoustic cavity only forms a waterproof barrier through the bonding and fixing between the front cover and the coated tape of the diaphragm. In order to improve the reliability of the waterproof barrier, it is usually necessary to increase the coated tape of the diaphragm. width, but blindly increasing the width of the coated tape will affect the area of ​​the diaphragm, which will cause a loss of sensitivity. Therefore, it is very necessary to improve the waterproof structure of the speaker monomer to provide a new waterproof barrier

Abstract

The invention discloses a loudspeaker single body and an assembly method thereof. The loudspeaker single body comprises an outer shell (2), a front cover (1), a finished vibrating diaphragm (3) and an annular sealing body (4), wherein an edge portion (31) of the finished vibrating diaphragm (3) is fixed connected between the front cover (1) and the outer shell (2), so as to form an annular joint region (7) between the edge portion (31) and the front cover (1); the finished vibrating diaphragm (3) is obtained through cutting an original vibrating diaphragm (3') provided with an external supporting ring (31'), and the external supporting ring (31') is arranged on the external part of the front cover (1) and the outer shell (2) and is used for positioning the original vibrating diaphragm (3') in the assembly process; and the annular sealing body (4) surrounds the annular joint region (7), and is configured to perform waterproof sealing on the annular joint region (7).

Description

technical field [0001] The present invention relates to the technical field of electro-acoustic products, and more specifically, the present invention relates to a loudspeaker unit and an assembly method of the loudspeaker unit. Background technique [0002] The speaker unit is an electro-acoustic device that converts electrical signals into sound signals. The loudspeaker unit includes a casing, a front cover, a magnetic circuit assembly and a vibration assembly, and the magnetic circuit assembly and the vibration assembly are accommodated in a space surrounded by the casing and the front cover. The vibration component includes a voice coil and a diaphragm fixedly connected to the voice coil. The edge of the diaphragm is coated with tape. The diaphragm is bonded and fixed to the shell on one side and the front cover on the other side through the tape. In order to divide the above-mentioned space into a front acoustic cavity on the front cover side and a rear acoustic cavity...
