[0015] The utility model vibration suppression loudspeaker is used to produce sound, can be embedded in the audio frequency equipment such as TV set, car and use as sound equipment. Referring to Figures 1 to 3 , the vibration suppression loudspeaker includes basket 2, magnetic circuit part 3, sound emitting part 4, mounting bracket 5, vibration damping member 6, spring wave 7 and folded ring 8. Basket 2 is the main external structure of the utility model vibration suppression loudspeaker, is used to install each part, and provides supporting force. Basket 2 includes upper basket 21, lower basket 22 and middle basket 23, and middle basket 23 is located between upper basket 21 and lower basket 22 and connects upper basket 21 and lower basket 22. Upper basket 21, lower basket 22 and middle basket 23 can be integrally injection molded. Magnetic circuit part 3 is mainly used to form magnetic circuit and is installed at the lower end of lower basket 22. Referring to Figure 4The magnetic circuit part 3 comprises a magnetic steel 31, a lower clamping plate 32 and an upper clamping plate 33. The magnetic field is provided by the magnetic steel 31. The magnetic steel 31, together with the upper clamping plate 32 and the lower clamping plate 31, forms a magnetic circuit, which determines the magnetic field strength of the loudspeaker. The sound generating part 4 is installed on the basket 2 and above the magnetic circuit part 3. The sound generating part 4 comprises a voice coil 41 and a cone 42. The upper part of the voice coil 41 is connected to the lower part of the cone 42. A part of the voice coil 41 is inserted into the gap G of the magnetic circuit part 3 and does not contact the magnetic circuit part 3. The rubber bump 7 is connected to the voice coil 41 and the lower basket 22 respectively. The rubber bump 7 can buffer the vibration generated by the voice coil 41, so as to reduce the vibration transmitted to the lower basket 22. The folding ring 8 is connected to the upper part of the cone 42 and the upper basket 21 respectively. The folding ring 8 can buffer the vibration generated by the cone 42, so as to reduce the vibration transmitted to the upper basket 21. The sound generating part 4 is installed on the basket 2 through the rubber bump 7 and the folding ring 8. The rubber bump 7 and the folding ring 8 can also buffer the vibration transmitted by the sound generating part 4 to the basket 2. The dust cover 2a is arranged on the upper side of the through hole in the center of the cone 42, so as to prevent foreign matters from entering the inside of the loudspeaker. Other components of the loudspeaker are arranged in the inside of the basket 2. After the voice coil 41 is connected to the power supply, the voice coil 41 interacts with the magnetic field and vibrates up and down along the axis A, so as to drive the cone 42 to vibrate and generate sound. Figure 4 The voice coil 41 interacts with the magnetic field and vibrates up and down along the axis A, so as to drive the cone 42 to vibrate and generate sound.

[0016] Referring to Figure 3 The lower part of the upper basket 21 of the basket 2 is provided with the vibration buffer 6 and the mounting bracket 5. The vibration buffer 6 is arranged between the upper basket 21 and the mounting bracket 5 and is connected to the upper basket 21 and the mounting bracket 5. The whole vibration suppression loudspeaker is installed on the external device through the mounting bracket 5, such as being installed on the door panel of a vehicle through the mounting bracket 5, so as to be installed on the vehicle.

[0017] The vibration buffer 6 is used to buffer the vibration of the basket 2 before transmitting the vibration to the mounting bracket 5. The vibration buffer 6 is a component for buffering the vibration generated by the sound generating part 4 and is made of rubber or other elastic materials. In the embodiment, the vibration buffer 6 is made of rubber. Referring to Figures 5 to 7The vibration buffer 6 is generally annular, including a buffer body 60, an upper fixing protrusion 631, and a lower fixing protrusion 632. The buffer body 60 connects the upper fixing protrusion 631 and the lower fixing protrusion 632, which are located above and below the buffer body 60, respectively. The buffer body 60, the upper fixing protrusion 631, and the lower fixing protrusion 632 are all annular and coaxial. The upper basin frame 21 is provided with an annular upper fixing groove 24. The opening of the upper fixing groove 24 faces downward, and its shape is adapted to the upper fixing protrusion 631. Its size can be slightly smaller than that of the upper fixing protrusion 631. The upper fixing protrusion 631 is inserted into and tightly locked in the upper fixing groove 24 through elastic deformation, thereby installing the vibration buffer 6 onto the basin frame 2. The installation is secure and convenient. The mounting bracket 5 has a circular lower fixing groove 51 with its opening facing upwards. The groove's shape matches the lower fixing protrusion 632, but its size can be slightly smaller. The lower fixing protrusion 632 is elastically inserted into and tightly locked into the lower fixing groove 51, thus installing the vibration buffer 6 onto the mounting bracket 5. The installation is secure and convenient. The upper basin frame 21 is placed on the upper side of the vibration buffer 6. Figure 7 The mounting bracket 5 is placed below the vibration buffer 6 (in the Z-axis direction), and both the upper basin frame 21 and the mounting bracket 5 provide fixing force for the vibration buffer 6. The lower part of the mounting bracket 5 is approximately at the same height as the lower basin frame 22 (in the Z-axis direction). This structure prevents the vibration buffer 6 from detaching from the basin frame 21 or the mounting bracket 5. This utility model uses a single component, the vibration buffer 6, to connect the basin frame 2 and the mounting bracket 5. The vibration of the basin frame is transmitted to the vibration buffer, which first buffers and reduces the transmitted vibration before transmitting it to the mounting bracket, greatly reducing the vibration of the mounting bracket.

[0018] The buffer body 60 is used to buffer the vibration transmitted from the basin frame 2, and is located on the outer sides of the upper fixed protrusion 631 and the lower fixed protrusion 632. The middle part of the buffer body 60 protrudes outward in an arc shape, forming a buffer groove 61 located on the inner side. The curvature of the buffer body 60 is determined by the size of the buffer groove 61. The outer surface 60a is the outer curved surface of the buffer body 60, and the inner surface 60b is the inner wall surface of the buffer body 60. When the buffer body 60 receives the vibration transmitted from the basin frame 2, it absorbs the vibration energy through the expansion and contraction of the buffer groove 61, thereby achieving a buffering effect. Moreover, the buffer body 60 has a ring-shaped structure, and only... Figure 3The direction of the middle A-axis vibration forms a buffer. This form of change of curvature of the buffer body 60 has higher buffering performance than the form of straight line of the buffer body 60. A plurality of support ribs 62 are arranged on the inner side 60b of the buffer body 60, and the plurality of support ribs 62 are distributed at equal intervals along the circumferential direction of the buffer body 60, so as to provide uniform support force for the buffer body 60, and make the buffer body 60 have certain rigidity performance. The support ribs 62 can provide strong and stable uniform support force while transmitting the vibration of the buffer pot frame 2.

[0019] The vibration buffer piece of the vibration suppression loudspeaker directly connects the pot frame and the mounting frame, has a very simple structure, reduces the assembly work number of the loudspeaker, reduces the production cost, and improves the production efficiency; the vibration of the loudspeaker pot frame is transmitted to the vibration buffer piece, the buffer body absorbs vibration energy through expansion, reduction and other actions of the buffer groove, so as to achieve the buffering effect; the vibration buffer piece transmits the vibration after buffering and reducing to the mounting frame, so that the vibration of the mounting frame is greatly reduced. For the vibration suppression loudspeaker, the vibration of the pot frame is transmitted to the vibration buffer piece, the vibration buffer piece transmits the vibration after buffering and reducing to the mounting frame, so that the vibration of the mounting frame is greatly reduced, and the vibration suppression effect is remarkable.
