DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Please refer to Figure 1-4 ;

[0021] The speaker described in the present invention adopts a dual-sound disc design, which can provide good sound quality at a low cost. It specifically includes a frame 1, and a magnetic circuit assembly 2 is provided in the middle of the frame 1. The magnetic circuit assembly 2 in this embodiment contains a magnet 22 and a washer 21, or can refer to the relevant design in the prior art. A voice coil 3 is provided on the outer periphery of the magnetic circuit assembly 2, and the voice coil 3 is connected to a damper 4. The outer edge of the damper 4 is fixed to the frame 1, and the damper 4 plays a role in centering the voice coil 3. The difference between the present invention and the prior art is that an aluminum pot sound disc 5 is fixed to the frame 1, and a paper sound disc 6 is provided at the bottom of the aluminum pot sound disc 5. One end of the paper sound disc 6 is connected to the aluminum pot sound disc 5, and the other end extends to the voice coil 3. The voice coil 3 passes through the paper sound disc 6 and is connected to the aluminum pot sound disc 5. There is a gap between the paper sound disc 6 and the voice coil 3 to prevent touching the voice coil 3 and generating sound, and affecting the output effect.

[0022] When playing music, a changing electrical signal is input into the voice coil 3, causing it to move up and down relative to the magnetic circuit assembly 2, pushing the aluminum pot sound plate 5 to move synchronously, causing the air to vibrate and produce sound. The aluminum pot sound plate 5 has high rigidity and instantaneous explosive power, which can respond quickly during performance and produce a strong sound effect, suitable for playing dynamic and powerful music. In addition, when the aluminum pot sound plate 5 moves, it also drives the paper sound plate 6 to move and vibrate. The design of the paper sound plate 6 makes the sound propagation more uniform, reduces sound distortion, and thus provides clearer and purer sound quality. The unique material and design of the paper sound plate 6 give the sound a unique timbre, making the music sound more natural and realistic. It can also simulate the effect of real music performance to a certain extent, bringing an immersive listening experience.

[0023] In the prior art, an aluminum pot sound disc 5 or a paper sound disc 6 is usually provided separately. Even if there is a combination of the aluminum pot sound disc 5 and the paper sound disc 6, only the outer periphery of the aluminum pot sound disc 5 is sealed with paper, and the proportion of paper is very small. Moreover, since the inner ring of the paper disc is connected to the aluminum pot sound disc 5 and the outer ring is connected to the bracket, the amplitude of the paper disc is very small, and it cannot produce a good effect.

[0024] In this embodiment, one end of the paper sound disk 6 is connected to the aluminum pot sound disk 5, and the other end has no constraints. When playing music, the paper sound disk 6 can have a larger amplitude, which can fully release the characteristics of the paper sound disk 6, so that the speaker has better sound quality effects. In addition, the production cost is low, which can meet the needs of most people.

[0025] Furthermore, the paper sound disc 6 is in the shape of an inverted cone, and the inner side of the upper end of the paper sound disc 6 is an arc surface, which not only allows the paper sound disc 6 to be better fixed to the aluminum pot sound disc 5, but also allows the paper sound disc 6 to have a larger area of ​​contact with the aluminum pot sound disc 5, which is more conducive to the transmission of vibration.

[0026] In one embodiment of the frame 1 of the present invention, the frame 1 includes an integrally formed mounting panel 11 and a fixing frame 12. The mounting panel 11 is square and is used to connect with parts such as an audio housing. A mounting position 13 adapted to the shape of the aluminum pot sound disc 5 is provided in the middle thereof. The fixing frame 12 is provided with a mounting hole 14 for mounting the magnetic circuit assembly 2 at a position corresponding to the mounting position 13. In this embodiment, the magnetic circuit assembly 2 has, in addition to the magnet 22 and the washer 21, a supporting member 23 fixed in the mounting hole 14. The supporting member 23 is initially separated from the fixing frame 12. During assembly, the magnet 22, the washer 21 and the supporting member 23 can be assembled together in advance, and then the supporting part can be connected and fixed to the fixing frame 12 using glue or other materials. At the same time, the aluminum pot sound disc 5, the voice coil 3 and the paper sound disc 6 are assembled together. Finally, the aluminum pot sound disc 5 is placed in the mounting position 13 and fixed to the mounting panel 11. Such a modular installation method is more convenient and efficient.

[0027] Furthermore, the fixing frame 12 is connected to the mounting panel 11 through a plurality of columns 15. The plurality of columns 15 are evenly spaced, and a slot 16 is installed on each of the plurality of columns 15 for connecting to a wire connector 17. With such a design, the wire connector 17 can be installed on any of the columns 15. During assembly, the wire connector 17 can be installed first, and the specific position of the voice coil 3 can be adjusted later. This makes assembly more flexible.

[0028] Furthermore, the damper 4 is mounted on the mounting bracket 12, creating a relatively enclosed space. The vibration of the damper 4 causes the air within this space to vibrate, preventing it from being dissipated, resulting in noise. To address this, a number of through-holes 18 are provided in a circular array on the sidewall of the mounting bracket 12. These through-holes 18 are located below the damper 4, allowing air exchange within this space through these through-holes 18 to reduce noise generation.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
