[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The present invention is further described below in conjunction with specific embodiments:

[0027] Example 1

[0028] like Figure 1-2As shown, a resonance-eliminating tweeter comprises a tweeter main body 1, a mounting panel 2 and a vibration-damping connector 3. The tweeter main body 1 is arranged in the middle of the mounting panel 2. The tweeter main body 1 and the mounting panel 2 are connected by the vibration-damping connector 3. The tweeter main body 1 is the core part of the speaker system and is responsible for emitting high-frequency sound. The mounting panel 2 provides a stable mounting plane for the tweeter main body 1 and can be connected to other structures (such as vehicle interiors, building walls, etc.). The vibration-damping connector 3 is used to connect the tweeter main body 1 and the mounting panel 2, and has a vibration-damping function to reduce the transmission of vibration generated by the speaker during operation to the mounting panel 2, thereby reducing noise and improving sound quality. The vibration-damping connector 3 and the mounting panel 2 are connected by fixing bolts 4. The fixing bolts 4 fix the vibration-damping connector 3 on the mounting panel 2 to ensure the stability and safety of the speaker. A decorative ring 5 is arranged above the fixing bolts 4. The decorative ring 5 can cover the fixing bolts 4 to make the appearance of the speaker more beautiful.

[0029] The tweeter speaker body 1 includes an outer shell 11 and a connecting seat 14. The bottom of the outer shell 11 is an open structure. The outer shell 11 serves as a cavity for sound radiation and protects internal components. A sound diaphragm 12 is arranged inside the outer shell 11. The sound diaphragm 12 vibrates to generate sound. It vibrates as the magnetic field generated by the voice coil 13 changes, pushing the air to generate sound waves. The bottom of the sound diaphragm 12 is clamped with the top of the voice coil 13. After the audio signal is passed through the voice coil 13, a changing magnetic field is generated, which interacts with the magnetic steel ring 16 to drive the sound diaphragm 12 to vibrate. An adhesive layer is arranged at the connection between the sound diaphragm 12 and the voice coil 13. The adhesive layer is used to firmly bond the sound diaphragm 12 to the connecting seat 14 to ensure effective transmission of vibration. The connecting seat 14 is arranged below the sound membrane 12, and the connecting seat 14 is bonded to the outer shell 11 and the sound membrane 12. The connecting seat 14 connects the sound membrane 12 and the outer shell 11 to provide support for the sound membrane and serve as a bridge for sound transmission. A T-shaped iron 17 is sleeved on the bottom of the voice coil 13. The T-shaped iron 17 serves as a bracket of the voice coil 13 and also as a component of the magnetic circuit to enhance the concentration of the magnetic field. A magnetic steel ring 16 and a clip 15 are sleeved on the top of the T-shaped iron 17. The clip 15 is arranged above the magnetic steel ring 16. The magnetic steel ring 16 generates a constant magnetic field, interacts with the voice coil 13, and drives the sound membrane 12 to vibrate. The clip 15 fixes the position of the magnetic steel ring 16 and the T-shaped iron 17 to ensure the stability of the magnetic circuit.

[0030] Bolt holes are provided at the edges of the outer shell 11, and the outer shell 11 is connected to the vibration-damping connector 3 by bolts passing through the bolt holes. The vibration-damping connector 3 effectively reduces the resonance of the speaker during operation, and improves the clarity and sound quality of the sound. The use of fixing bolts 4 and decorative rings 5 ​​ensures the stability and safety of the speaker on the mounting panel. The cooperation of the sound membrane 12, voice coil 13, magnetic steel ring 16 and T-iron 17 realizes the efficient conversion of electrical energy to sound energy. The design of the decorative ring 5 not only covers the fixing bolts, but also enhances the aesthetic appearance of the speaker.

[0031] Example 2

[0032] When a traditional speaker is playing, vibration is easily transmitted to the mounting panel through the fixed structure, causing noise and resonance. The vibration transmission will cause the sound quality of the speaker to be damaged, especially the treble part, affecting the sound quality. In order to further solve the problems of vibration transmission, sound quality damage, structural stability and installation flexibility in the existing speaker technology, reference Figure 1 and Figure 3 As shown, this embodiment is provided with a connection structure for reducing the resonance effect of the health-care machine.

[0033] A connecting ring 31 is provided on one side of the vibration-damping connector 3, and a slot matching the size of the vibration-damping washer 6 is provided below the connecting ring 31. The vibration-damping washer 6 is arranged inside the slot. The connecting ring 31 is connected to the mounting panel 2 by a fixing bolt 4. The vibration-damping washer 6 can absorb and buffer the vibration generated by the speaker, thereby reducing the vibration transmitted to the mounting panel 2.

[0034] A circular frame 32 and a vibration reduction ring 37 are provided on the side of the vibration-damping connecting member 3 away from the connecting ring 31. The circular frame 32 is provided above the vibration reduction ring 37. A connecting block 35 is slidably provided between the circular frame 32 and the vibration reduction ring 37. The bottom of the connecting block 35 is in sliding contact with the top surface of the vibration reduction ring 37. A guide column 33 is horizontally provided inside the circular frame 32. Both ends of the guide column 33 are fixedly connected to the inner wall of the circular frame 32. The bottom of the connecting block 35 is in sliding contact with the top surface of the vibration reduction ring 37, and the top is slidably provided on the guide column 33 through a slide 36. This sliding structure allows the connecting block 35 to slide on the vibration reduction ring 37 when the speaker vibrates, thereby reducing the direct transmission of vibration.

[0035] A slide 36 is provided on the top of the connecting block 35, and the slide 36 is slidably set on the guide column 33. A vibration reduction spring 34 is arranged around the guide column 33. The two ends of the vibration reduction spring 34 are respectively abutted against the slide 36 and the circular frame 32. A connecting hole is opened on the top surface of the connecting block 35 away from the slide 36. The connecting block 35 is connected to the outer shell 11 by bolts through the connecting hole. When the speaker vibrates, the vibration reduction spring 34 can be compressed and stretched to absorb vibration energy and reduce the vibration transmitted to the installation panel 2. The guide column 33 is horizontally arranged inside the circular frame 32 to provide a stable sliding path for the connecting block 35 to ensure effective absorption of vibration energy and reduce transmission.

[0036] When the speaker starts working, the vibration-damping gasket 6 first absorbs and buffers the initial vibration generated by the speaker. The connecting block 35 slides on the vibration-reducing ring 37, allowing the speaker body to have a certain amount of movement space when vibrating, instead of directly transmitting the vibration to the fixed structure. The vibration-reducing spring 34 works between the connecting block 35 and the circular frame 32 to absorb the energy generated by the vibration of the speaker and reduce the transmission of vibration. The guide column 33 ensures that the sliding of the connecting block 35 is smooth and controllable, avoiding additional vibration caused by improper sliding. The connecting block 35 is connected to the outer shell 11 by bolts. This connection method not only ensures the stability of the structure, but also does not directly transmit vibration due to the presence of the vibration-reducing spring 34.

[0037] A vibration-damping gasket 7 is provided between the circular frame 32 and the outer shell 11 , and the vibration-damping gasket 7 is made of rubber material.

[0038] The vibration reduction ring 37 is provided with a mounting plate and a spring column 38 inside. The lower surface of the mounting plate is fixedly connected to one end of the spring column 38 by a bolt, and the other end of the spring column 38 is movably connected to one side of the inner wall of the vibration reduction ring 37 by a pin shaft. The spring column 38 is covered with a spring. The mounting plate cooperates with the spring column 38 to effectively ensure that the vibration reduction ring 37 vibrates during the vibration of the tweeter main body 1, thereby avoiding the separation of the vibration reduction ring 37 from the tweeter main body 1. The spring covered with the spring column 38 constitutes a suspension system, which can provide elastic support when the tweeter main body 1 vibrates. The spring can absorb and isolate vibration and reduce the transmission of vibration. One end of the spring column 38 is movably connected to the inner wall of the vibration reduction ring 37 by a pin shaft. This movable connection allows the vibration reduction ring 37 to move freely when the speaker vibrates, thereby reducing the vibration transmission at the fixed point. The spring not only provides elastic support, but also has a damping effect. Selecting the damping coefficient of the spring according to the tweeter main body 1 can more effectively absorb vibration energy and reduce the vibration transmitted to the mounting panel 2.

[0039] Example 3

[0040] In order to further reduce echo and resonance, improve the stability of the speaker system, and make the sound of the speaker clearer and more natural, refer to Figure 1 and Figure 4 As shown, on the basis of the above embodiment, a vibration-damping gasket 6 is provided between the vibration-damping connector 3 and the mounting panel 2. The vibration-damping gasket 6 includes a sound-absorbing pad 61 and a buffer pad 62. The sound-absorbing pad 61 is arranged on a side close to the mounting panel 2. The sound-absorbing pad 61 absorbs excess sound generated when the speaker is working, reduces echo and resonance, and the buffer pad 62 is arranged on a side close to the vibration-damping connector 3. The buffer pad 62 buffers and absorbs vibrations, further reducing resonance. A reinforcing gasket 63 is provided inside the buffer pad 62. The reinforcing gasket 63 is located inside the buffer pad 62, which can enhance the mechanical strength and durability of the vibration-damping gasket.

[0041] Specifically in this embodiment, the sound absorbing pad 61 is made of polyurethane foam material, and the buffer pad 62 is made of NR rubber material.

[0042] The sound-absorbing pad 61 is made of polyurethane foam material, and its porous structure can effectively absorb the excess sound generated when the speaker is working. The polyurethane foam material has excellent sound-absorbing performance, which can reduce the reflection of sound waves between the speaker and the installation panel, reduce echo and resonance, and thus improve the clarity and purity of the sound.

[0043] Secondly, the buffer pad 62 is made of NR rubber material, which has good elasticity and damping properties. When the speaker vibrates, the buffer pad 62 can effectively absorb and buffer the vibration energy, preventing these vibrations from being transmitted to the mounting panel 2, thereby reducing the resonance of the entire system. The natural elasticity of NR rubber ensures that the vibration reduction effect can remain stable even during long-term use, and the performance will not be reduced due to material fatigue.

[0044] In addition, the provision of the reinforcing washer 63 further enhances the mechanical strength and durability of the vibration-damping washer 6. The reinforcing washer 63 located inside the buffer pad 62 not only improves the overall structural stability of the vibration-damping washer, but also ensures that the vibration-damping washer will not be deformed or damaged during the vibration of the speaker, thereby extending its service life.

[0045] Specifically, the vibration-damping gasket 6 reduces echoes and resonances, making the sound emitted by the speaker clearer and more natural, and the sound quality is significantly improved. The vibration-damping design reduces vibration transmission, making the speaker more stable during playback and less susceptible to external vibrations. The material selection and structural design of the vibration-damping gasket 6 enable it to withstand long-term vibrations without damage, thereby extending the service life of the speaker. The high-quality sound quality and stable performance provide users with a more comfortable and pleasant listening experience. The design of the vibration-damping gasket 6 makes it suitable for a variety of environments and installation conditions, whether in a car or indoors, and can effectively reduce resonance.
