[0002] Most of the existing speakers on the market are single-magnet speakers. Single-magnet speakers have only one magnet, so the magnetic field generated is relatively weak, which may result in lower sound output power and fail to achieve the volume and sound pressure level that dual-magnet speakers of the same size can provide. The magnetic field distribution of single-magnet speakers may not be uniform enough, which may cause sound distortion or uneven frequency response, affecting the accuracy and balance of the sound quality. Therefore, those skilled in the art provide a dual-magnet single flat membrane high-frequency speaker to solve the problems raised in the above background technology. Utility Model Content

[0006] The support assembly includes two connecting blocks, a support frame is rotatably connected between the two connecting blocks, a plurality of slots are provided inside the connecting block, and the slots are arranged in a ring shape at the temporal part of the connecting block. Two slide grooves are provided inside the support frame, and two blocks are slidably connected inside the two slide grooves. One end of the block away from the connecting block is fixedly connected to a limiting plate, and a spring is fixedly connected between the two limiting plates.

[0007] As a further description of the above technical solution:

[0008] The auxiliary magnet is arranged opposite to the main magnet with the same polarity.

[0009] As a further description of the above technical solution:

[0010] The coil is located in the middle of the washer and outside the T-shaped iron and is not in contact with the T-shaped iron, the main magnet and the washer.

[0011] As a further description of the above technical solution:

[0017] The utility model has the following beneficial effects:

[0018] 1. In the present invention, the double magnetic design is used to improve the sound output power, thereby increasing the volume and sound pressure level. In addition, the double magnetic speaker makes the magnetic field distribution more uniform, thereby improving the accuracy and balance of the sound quality.

[0019] 2. In the utility model, through the design of the flat membrane, the diaphragm of the flat membrane speaker is relatively light and thin, with lower inertia, and therefore can respond to changes in electrical signals more quickly, which means that the flat membrane speaker can more accurately restore the details and dynamic range of the audio signal, making the music clearer and more realistic. In addition, since the flat membrane has a stronger restraining force, the frequency of its vibration in the tightened state is higher, thereby achieving its high-frequency effect.

[0020] 3. In the utility model, the spring pushes the card block to engage with the card slot to adjust the rotation angle of the support frame inside the connecting block and then adjust the tilt angle of the box body. On the one hand, it can support the box body, and on the other hand, it can adjust the propagation direction of the sound source. BRIEF DESCRIPTION OF THE DRAWINGS
