Description

Technical Field

[0001] The present invention relates to the technical field of speakers, and in particular to shock-absorbing speakers. Background Art

[0002] A speaker is an electroacoustic device that converts electrical signals into sound signals. It mainly consists of parts such as a magnet, a coil (voice coil), and a paper cone (or plastic diaphragm). When an audio current is passed through the voice coil of the speaker, a force will be generated on the voice coil under the action of the magnetic field. This force causes the voice coil to reciprocate in a direction perpendicular to the magnetic field in the magnetic field, thereby driving the paper cone to vibrate and produce sound.

[0003] After retrieval, a Chinese patent with the publication number CN114979855A discloses a heat-dissipating and shock-absorbing speaker, including a speaker body. One end of the outer side of the speaker body is fixedly installed with a support shell. The top surface of the speaker body is provided with a top plate. The top plate is rotatably connected to the outer side of the support shell. With the setting of the top plate, the top plate is located outside the speaker body, which can effectively prevent sunlight from directly irradiating the speaker body, greatly reducing the surface temperature of the speaker body, thereby reducing the problem of the coil being burned out by high temperature. At the same time, with the rotatable connection setting of the top plate, the contact rod contacts the outer side of the speaker body, allowing part of the vibration effect to be transmitted to the contact rod and the top plate, causing the rotatably connected top plate to swing, thereby consuming part of the vibration effect. Through this setting, not only is direct sunlight reduced, and damage to the speaker caused by high temperature is reduced, but also a shock-absorbing effect is provided, enabling the speaker to be stably suspended at a high place. However, when this solution is actually used, there are still the following deficiencies: Using the mechanism of the top plate shaking for shock absorption can absorb and disperse the vibration energy generated by the speaker's own operation to a certain extent. However, the top plate is usually firmly installed on the support shell to ensure the stability and positioning accuracy of the entire structure. But when the top plate shakes during shock absorption, this dynamic movement may generate continuous tiny stresses on the installation interface of the support shell. Over time, these accumulated stresses may cause the installation of the support shell to gradually become loose. The support shell is a key support structure of the speaker system, and its stability is directly related to the fixation of the speaker unit, the maintenance of acoustic performance, and the reliability under long-term use. Once the installation of the support shell becomes loose, it will not only affect the acoustic characteristics such as the directivity and frequency response of the speaker, but also may cause sound distortion and increased noise due to unstable structure.

[0004] Therefore, it is necessary to design a shock-absorbing speaker to solve the above problems. Summary of the Invention

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Referring to Figures 1-11 , a shock-absorbing speaker, comprising a housing unit, a shock-absorbing unit, a linkage unit, a cleaning unit, and a temperature-reducing unit. The housing unit includes two mounting plates 11 and a fixed housing 12 fixedly installed on the inner wall of the mounting plate 11. Two mounting grooves 13 are opened on the side of the fixed housing 12. A speaker housing 21 is fixedly installed on the inner wall of the mounting groove 13. A speaker body 22 is arranged on the inner wall of the speaker housing 21 through a bracket. A mask 23 is arranged at the end of the speaker housing 21. Connecting wires 14 adapted to the speaker body 22 are arranged on both mounting plates 11. One ends of the two connecting wires 14 far away from the mounting plates 11 are provided with plugs 15; The shock-absorbing unit includes an air supply airbag ring 31 fixedly installed on the outer wall of the speaker body 22, a pressing ring 32 fixedly installed on the side of the air supply airbag ring 31, and an elastic airbag ring 33 fixedly installed on the inner wall of the opening end of the speaker housing 21. The air supply airbag ring 31 is communicated with the elastic airbag ring 33 through a conduit 34. A transmission structure is arranged inside the speaker body 22; The transmission structure includes a shaft rod 35 rotatably installed on the inner wall of the speaker housing 21, a rotating plate 36 sleeved on the shaft rod 35, and a torsion spring 37 sleeved on the shaft rod 35. One end of the rotating plate 36 is fixedly installed with an ejector rod 38 corresponding to the folding ring. The end of the rotating plate 36 far away from the ejector rod 38 extends to the position of the pressing ring 32. The distance between the ejector rod 38 and the shaft rod 35 is much smaller than the distance between the pressing ring 32 and the shaft rod 35; During use, the mounting plate 11 can be fixed at the installation position by screws, and the speaker body 22 can be powered on through the plug 15. When working normally, the speaker body 22 can generate sound through vibration. During the vibration process, the surround in the speaker body 22 can vibrate with the sound. Under the action of the torsion spring 37, the ejector rod 38 at the end of the rotating plate 36 can always be in contact with the outer wall of the surround. When the surround vibrates, it can push the ejector rod 38 and drive the shaft rod 35 and the rotating plate 36 to rotate. Since the distance from the ejector rod 38 to the shaft rod 35 is much smaller than the distance from the pressure ring 32 to the shaft rod 35, under the action of the lever principle, when the surround drives the rotating plate 36 to rotate, it can press the pressure ring 32. When the surround vibrates outwards, it can press down the pressure ring 32 through the rotating plate 36, so that the gas in the air supply airbag ring 31 is guided to the elastic airbag ring 33 through the conduit 34. The elastic airbag ring 33 can be inflated and expanded. When the surround vibrates inwards, the rotating plate 36 can be separated from the pressure ring 32, and the elastic airbag ring 33 can reset under its own elastic force and fill the gas into the air supply airbag ring 31. When the speaker body 22 vibrates, its vibration direction is opposite to the air supply and discharge direction of the elastic airbag ring 33. The elastic airbag ring 33 can play a role in damping the speaker body 22, effectively reducing the vibration amplitude of the speaker body 22.

[0021] The linkage unit includes a connecting shell 41 fixedly installed on the inner wall of the speaker housing 21, an energized coil 42 arranged inside the connecting shell 41, and a metal rod 43 arranged inside the energized coil 42. The energized coil 42 is electrically connected to the speaker body 22 through a wire. A guide rod 44 is fixedly installed on the inner wall of the connecting shell 41 at a position opposite to the metal rod 43. A sliding plate 45 is sleeved on the guide rod 44 in a sliding manner. A spring 46 is sleeved on the outer wall of the guide rod 44 between the connecting shell 41 and the sliding plate 45. A connecting rack 47 is fixedly installed on the side of the sliding plate 45. A transmission gear 48 meshing with the connecting rack 47 is rotatably installed on the inner wall of the connecting shell 41 through a mounting rod. A bevel gear one 49 is arranged on the side of the transmission gear 48. The transmission gear 48 and the bevel gear one 49 are connected through a one-way bearing. A support rod 410 is rotatably installed on the inner wall of the connecting shell 41. A bevel gear two 411 meshing with the bevel gear one 49 is fixedly installed at the end of the support rod 410; When the speaker body 22 is working, since the power coil 42 is electrically connected to the speaker body 22 through a wire, and the current passed through the speaker body 22 is of different magnitudes, the power coil 42 can generate a magnetic force as a whole under the action of the metal rod 43 inside it after being energized. Since the magnitude of the current passed through the power coil 42 is changing, the magnitude of the generated magnetic force is also changing. In addition, the connecting shell 41 is made of aluminum material, which effectively isolates the influence of the magnetic force generated by the power coil 42 on the speaker body 22. The slide plate 45 is made of metal material, so that after the power coil 42 generates a magnetic force, it can adsorb the slide plate 45 on the guide rod 44, so that the slide plate 45 Sliding along the guide rod 44, and because the magnitude of the magnetic force is changing, the slide plate 45 can slide back and forth on the guide rod 44 under the action of the spring 46. During the reciprocating sliding of the slide plate 45, the transmission gear 48 can be driven to rotate by connecting the rack 47. When the transmission gear 48 rotates, it is connected to the bevel gear 1 49 through a one-way bearing. Therefore, when the transmission gear 48 rotates forward, it cannot drive the bevel gear 1 49 to rotate. When the transmission gear 48 rotates reversely, it can drive the bevel gear 1 49 to rotate. When the bevel gear 1 49 rotates, it can drive the bevel gear 2 411 meshing with it to rotate, thereby driving the support rod 410 in one direction.

[0022] The cleaning unit includes a rotating seat 51 rotatably mounted on the side of the mask 23, a rotating rod 52 is rotatably mounted on the outer wall of the rotating seat 51, and a cleaning structure is arranged on the rotating rod 52; The cleaning structure includes a cleaning roller 53 mounted on a rotating rod 52, the outer wall of the cleaning roller 53 is provided with flexible bristles, a linkage gear 54 is mounted on one end of the rotating rod 52 away from the rotating seat 51, a fixed gear ring 55 meshing with the linkage gear 54 is fixedly mounted on the side of the mask 23, a protective shell 57 is fixedly mounted on the outer wall of the speaker shell 21, a transmission rod 56 is rotatably mounted on the inner wall of the protective shell 57, and both ends of the transmission rod 56 are respectively connected to the support rod 410 and the rotating seat 51 through a driven wheel and a synchronous belt; The support rod 410 is connected to the transmission rod 56 on the inner side of the protective shell 57 through a driven wheel and a synchronous belt transmission. Therefore, when the support rod 410 rotates, the transmission rod 56 can be driven to rotate. The transmission rod 56 is connected to the rotating seat 51 through the driven wheel and the synchronous belt, so it can drive the rotating seat 51 to rotate. When the rotating seat 51 rotates, it can drive the rotating rod 52 to revolve. The linkage gear 54 at the end of the rotating rod 52 is meshed with the fixed gear ring 55 on the side of the mask 23. Then, when the rotating rod 52 revolves, the linkage gear 54 and the fixed gear ring 55 can drive the rotating rod 52 and the cleaning roller 53 to rotate. When the cleaning roller 53 rotates, the flexible bristles on its outer wall can be used to clean the mask 23 to prevent the mask 23 from being affected by dust, while improving the sound quality of the speaker.

[0023] The temperature reduction unit includes a cooling pipe 61 disposed inside the speaker housing 21. The cooling pipe 61 is arranged in a spiral shape. A liquid storage box 62 is provided on the side of the speaker housing 21. A semiconductor refrigerant plate 63 is installed on the inner wall of the liquid storage box 62. The liquid storage box 62 is communicated with the liquid outlet end of the cooling pipe 61 through a return pipe 64. A liquid supply pipe 65 is provided at the liquid inlet end of the cooling pipe 61. A transmission disk 66 is fixedly installed at the end of the transmission rod 56. A liquid pumping box 67 corresponding to the liquid storage box 62 is fixedly installed on the side of the speaker housing 21, and the liquid supply pipe 65 is communicated with the liquid pumping box 67. A push rod 68 penetrates through the side of the liquid pumping box 67. A sliding plug 69 is fixedly installed at one end of the push rod 68 located inside the liquid pumping box 67. A connecting rod 610 is rotatably installed at the side edge position of the transmission disk 66. One end of the connecting rod 610 away from the transmission disk 66 is rotatably connected to the end of the push rod 68. The liquid storage box 62 is connected to the liquid pumping box 67 through a communicating pipe 611. Check valves with opposite flow directions are installed on the inner walls of the communicating pipe 611 and the liquid supply pipe 65; While the transmission rod 56 rotates, it can drive the transmission disk 66 to rotate. The liquid storage box 62 is filled with a coolant. When the transmission disk 66 rotates, it can reciprocally push the push rod 68 through the connecting rod 610, so that the sliding plug 69 can reciprocally slide in the liquid pumping box 67. During the reciprocal sliding of the sliding plug 69, due to the installation of check valves with opposite flow directions in the communicating pipe 611 and the liquid supply pipe 65, when the sliding plug 69 slides outwards with the push rod 68, it can pump the coolant in the liquid storage box 62 into the liquid pumping box 67 through the communicating pipe 611. When the sliding plug 69 slides in the opposite direction, it can push the coolant in the liquid pumping box 67 into the cooling pipe 61 through the liquid supply pipe 65. The circulating coolant in the cooling pipe 61 can be re-directed to the liquid storage box 62 through the return pipe 64 for cooling circulation. The semiconductor refrigerant plate 63 in the liquid storage box 62 can quickly cool the coolant in the liquid storage box 62 for use. The working principle and connection method of the semiconductor refrigerant plate 63 are existing mature technologies and will not be elaborated here.

[0024] The specific working principle of the present invention is as follows: During use, the mounting plate 11 can be fixed at the mounting position by screws, and the speaker body 22 can be powered on through the plug 15. When working normally, the speaker body 22 can generate sound through vibration. During the vibration process, the surround in the speaker body 22 can vibrate with the sound. Under the action of the torsion spring 37, the ejector rod 38 at the end of the rotating plate 36 can always be in contact with the outer wall of the surround. When the surround vibrates, it can push the ejector rod 38 and drive the shaft rod 35 and the rotating plate 36 to rotate. Since the distance from the ejector rod 38 to the shaft rod 35 is much smaller than the distance from the pressure ring 32 to the shaft rod 35, under the action of the lever principle, when the surround drives the rotating plate 36 to rotate, it can press the pressure ring 32. When the surround vibrates outwards, it can press down the pressure ring 32 through the rotating plate 36, so that the gas in the air supply airbag ring 31 is guided to the elastic airbag ring 33 through the conduit 34. The elastic airbag ring 33 can be inflated and expanded. When the surround vibrates inwards, the rotating plate 36 can be separated from the pressure ring 32, and the elastic airbag ring 33 can reset under its own elastic force and fill the gas into the air supply airbag ring 31. When the speaker body 22 vibrates, its vibration direction is opposite to the inflation and deflation direction of the elastic airbag ring 33. The elastic airbag ring 33 can play a role in damping the speaker body 22, effectively reducing the vibration amplitude of the speaker body 22; When the speaker body 22 works, since the energized coil 42 is electrically connected to the speaker body 22 through a wire, and the current passing through the speaker body 22 varies, after the energized coil 42 is powered on, a magnetic force can be generated as a whole under the action of the inner metal rod 43. Since the magnitude of the current passing through the energized coil 42 is changing, the magnitude of the generated magnetic force is also changing. And the connection shell 41 is made of aluminum material, effectively isolating the influence of the magnetic force generated by the energized coil 42 on the speaker body 22. The sliding plate 45 is made of metal material. Therefore, after the energized coil 42 generates a magnetic force, it can adsorb the sliding plate 45 on the guide rod 44, making the sliding plate 45 slide along the guide rod 44. And because the magnitude of the magnetic force is changing, the sliding plate 45 can slide reciprocally on the guide rod 44 under the action of the spring 46. During the reciprocating sliding process of the sliding plate 45, it can drive the transmission gear 48 to rotate through the connecting rack 47. When the transmission gear 48 rotates, since it is connected to the first bevel gear 49 through a one-way bearing, the transmission gear 48 cannot drive the first bevel gear 49 to rotate when rotating forward, while the transmission gear 48 can drive the first bevel gear 49 to rotate when rotating backward. When the first bevel gear 49 rotates, it can drive the second bevel gear 411 meshing with it to rotate, so as to drive the support rod 410 in one direction; The support rod 410 is drivingly connected to the transmission rod 56 inside the protective housing 57 through a driven wheel and a synchronous belt. Therefore, when the support rod 410 rotates, it can drive the transmission rod 56 to rotate. The transmission rod 56 is drivingly connected to the rotating seat 51 through a driven wheel and a synchronous belt. Therefore, it can drive the rotating seat 51 to rotate. When the rotating seat 51 rotates, it can drive the rotating rod 52 to revolve. The linkage gear 54 at the end of the rotating rod 52 meshes with the fixed gear ring 55 on the side of the face mask 23. Thus, when the rotating rod 52 revolves, it can drive the rotating rod 52 and the cleaning roller 53 to rotate by themselves through the linkage gear 54 and the fixed gear ring 55. When the cleaning roller 53 rotates, it can clean the face mask 23 through the flexible bristles on its outer wall, avoiding the influence of dust on the face mask 23 and improving the sound quality of the speaker at the same time; While the transmission rod 56 is rotating, it can drive the transmission disc 66 to rotate. The liquid storage box 62 is filled with a coolant. When the transmission disc 66 rotates, it can reciprocally push the push rod 68 through the connecting rod 610, so that the sliding plug 69 can reciprocally slide in the liquid pumping box 67. During the reciprocal sliding of the sliding plug 69, due to the installation of check valves with opposite flow directions in the connecting pipe 611 and the liquid supply pipe 65, when the sliding plug 69 slides outwards with the push rod 68, it can pump the coolant in the liquid storage box 62 into the liquid pumping box 67 through the connecting pipe 611. When the sliding plug 69 slides in the opposite direction, it can push the coolant in the liquid pumping box 67 into the cooling pipe 61 through the liquid supply pipe 65. The coolant circulating in the cooling pipe 61 can be re-introduced into the liquid storage box 62 through the liquid return pipe 64 for cooling circulation. The semiconductor refrigerant plate 63 in the liquid storage box 62 can quickly cool the coolant in the liquid storage box 62 for use. The working principle and connection method of the semiconductor refrigerant plate 63 are existing mature technologies and will not be elaborated here.
