Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a super linear loudspeaker. Background Art

[0002] In conventional speakers, the volume (or amplitude) of the output sound typically increases linearly with increasing input signals, but this can cause distortion due to the speaker's physical limitations (such as the mechanical properties of the diaphragm and magnetic circuit saturation). Superlinear speakers reduce this distortion through a series of design optimizations, such as using special diaphragm materials, optimizing magnetic circuit structures, and adjusting voice coil parameters. This allows the output sound volume to maintain a closer linear relationship with the input signal over a wider input signal range. This design helps provide clearer and more accurate sound reproduction, especially at high volumes, by reducing sound distortion.

[0003] Therefore, compared to conventional speakers, the vibration system of superlinear speakers has greater up-and-down vibrations, and the overall structure of superlinear speakers needs to meet high-power and large-amplitude requirements. Currently, the diaphragm and bracket in superlinear speakers are not positioned, resulting in poor diaphragm consistency. Without positioning, the diaphragm may shift during vibration, resulting in a deviation from the expected vibration trajectory and affecting the sound reproduction quality. The shift of the diaphragm may also cause interference with the voice coil, magnets, etc., further exacerbating distortion and performance degradation. Utility Model Content

It should be noted that the following examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Similarly, the following examples are merely partial embodiments of the present invention and are not intended to be exhaustive.

[0024] like Figures 1 to 6 As shown, this solution provides a super linear loudspeaker.

[0025] See Figure 1 、 Figure 5 and Figure 6 , from top to bottom, it includes: a vibration system 2, a bracket 1 and a magnetic circuit system 4. The bracket 1 is used to support the vibration system 2 and the magnetic circuit system 4. The magnetic circuit system 4 includes a magnetic core 43, a magnet 42 and a U cup 41 from top to bottom. The U cup 41 is fixedly mounted on the inner side of the bracket 1. A receiving cavity is formed between the U cup 41 and the bracket 1. The magnetic core 43 and the magnet 42 are both fixed in the receiving cavity. The vibration system 2 includes a diaphragm 22. The vibration system 2 also includes a voice coil 21, which is mounted on the magnet 42. It also includes an FPC board 3, which is arranged between the U cup 41 and the bracket 1. In this embodiment, the bracket 1 is a square structure, and the U cup 41 is also a square structure that matches the bracket 1. The structures of the voice coil 21, the magnetic circuit system 4 and the FPC board 3 in the vibration system 2 are direct applications of the existing technology and will not be elaborated on here.

[0026] See Figures 1 to 5The diaphragm 22 is buckled with the bracket 1, and the diaphragm 22 is also a square structure that matches the bracket 1. The diaphragm 22 is provided with a sealing rib 221 extending toward the bracket 1, and the bracket 1 is correspondingly provided with a positioning groove 11, and the sealing rib 221 is fixedly embedded in the positioning groove 11. Preferably, the sealing rib 221 is provided around the edge of the diaphragm 22, and the sealing rib 221 is a closed structure; preferably, the sealing rib 221 is a closed square structure. The sealing rib 221 fits in with the positioning groove 11; of course, the shape of the sealing rib 221 and the positioning groove 11 can be adjusted accordingly according to the shape of the diaphragm 2 and the bracket 1. The sealing rib 221 is glued to the positioning groove 11. The cooperation between the sealing rib 221 and the positioning groove 11 can prevent moisture from penetrating into the interior of the speaker, thereby avoiding damage to the electronic components and mechanical structures inside the speaker. Furthermore, the sealing rib 221 can limit the relative position of the diaphragm 22 and the bracket 1, ensuring that the diaphragm 22 maintains a stable position during vibration, reducing displacement and distortion of the diaphragm 22 during vibration, thereby improving the sound quality and performance of the speaker.
