The inner side of the second diaphragm is provided with a second voice coil, and the second voice coil is suspended in the second accommodating cavity.

As a preferred solution, the thickness of the second membrane is greater than that of the first membrane, and the softness of the second membrane is greater than that of the first membrane.

As a preferred solution, the mass of the second voice coil is greater than that of the first voice coil.

As a preferred solution, the body includes a bracket, U-iron, magnet, washer, tuning paper and PC board, the U-iron is fixed in the middle of the bracket, the magnet is arranged on the front of the U-iron, and the Huasi The company is set on the magnet, the tuning paper is set on the back of the bracket, and the PC board is set on the tuning paper.

As a preferred solution, the peripheral edge of the first diaphragm is pressed and fixed to the front peripheral edge of the bracket through the first copper ring.

As a preferred solution, the peripheral edge of the second diaphragm is pressed against and fixed to the rear peripheral edge of the bracket through the second copper ring.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions:

By setting the first diaphragm and the first voice coil on the front of the body, and setting the second diaphragm and the second voice coil on the back of the body, this product can make the low frequency of the speaker dive deeper functionally, and the sound is powerful. The sound quality is beautiful and pleasing to the ear, and there is no need to increase the speaker unit and frequency divider to improve the sound quality, which effectively reduces the cost of use.

In order to illustrate the structural features and functions of the utility model more clearly, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
