Description

Technical Field

[0001] The present invention belongs to the technical field of loudspeakers, and more specifically, particularly relates to a self-adjusting loudspeaker basin frame structure. Background Art

[0002] A loudspeaker, also known as a "horn", is a very commonly used electroacoustic transducer device. It can be found in all sound-generating electronic and electrical equipment. With the continuous development of audio technology today, loudspeakers are key devices for sound playback. Loudspeakers are transducers that convert electrical signals into acoustic signals. The performance of the speaker has a great impact on the sound quality.

[0003] At present, most speaker basin structures reduce the vibration of the device by setting a buffer mechanism, but the buffer mechanism in most devices is installed relatively fixedly and cannot be adaptively adjusted according to different usage environments and audio signals. In actual applications, speakers often face various complex working conditions, such as different volume levels, frequency ranges, and the influence of external vibration factors. When the audio signal intensity varies greatly, the traditional basin frame structure may not be able to effectively adjust the vibration state of the sound basin in a timely manner, resulting in sound distortion, unstable volume and other problems.

[0004] In addition, the existing sound basin is usually installed on the bracket by screwing bolts. During installation and removal, since the speakers are usually small in size and require tools to screw, the installation and removal process is relatively cumbersome and time-consuming, which is not conducive to subsequent maintenance and repair.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a self-adjusting speaker basin frame structure is provided, in order to achieve a purpose with greater practical value. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a self-adjusting speaker basket structure to solve the above problems.

[0007] A self-adjusting loudspeaker basin structure comprises a basin frame body, wherein a magnet is fixedly connected inside the basin frame body, a spring is sleeved on one end of the basin frame body close to the magnet, a sound basin body is clamped on one end of the basin frame body close to the magnet, the magnet is sleeved on the outer surface of the sound basin body, three groups of damping rods are fixedly connected to the lower end of the sound basin body, the outer surfaces of the three groups of damping rods are all sleeved with sleeves, three groups of rectangular blocks are fixedly connected to the lower end of the basin frame body, the three groups of rectangular blocks are rotatably connected with spur gears inside, the three groups of spur gears are threadedly connected with threaded rods inside, the upper ends of the three groups of threaded rods are fixedly connected with connecting seats, the three groups of connecting seats are respectively sleeved inside the three groups of sleeves, the basin frame body is rotatably connected with a driving mechanism, the driving mechanism comprises an internal gear, and the internal gear is rotatably connected to the basin frame body.

[0008] Preferably, the internal gears are meshed with three sets of spur gears, and the lower ends of the internal gears are fixedly connected with pull rods.

[0009] Preferably, one end of the lower end of the basin frame body close to the three groups of damping rods is fixedly connected to two connecting blocks, and a first slot is provided inside the two connecting blocks.

[0010] Preferably, the lower ends of the two connecting blocks are fixedly connected with a first spring, and the interior of the basin frame body is fixedly connected with two second springs.

[0011] Preferably, one side of the two second springs close to the connecting block is fixedly connected with a sliding block, and the two sliding blocks are respectively engaged in the two first slots.

[0012] Preferably, two inclined plane blocks are slidably connected inside the basin frame body, and rubber pads are sleeved on the outer surfaces of the two inclined plane blocks.

[0013] Preferably, inclined sliding grooves are provided inside the two sliding blocks, and the two inclined plane blocks are respectively fitted with the two inclined sliding grooves.

[0014] Preferably, two rectangular seats are fixedly connected to the inner surface of the basin frame body, and the two first springs are respectively sleeved inside the two rectangular seats.

[0015] Preferably, two positioning blocks are fixedly connected to one end of the lower end of the basin frame body close to the three groups of damping rods, two positioning grooves are provided inside the basin frame body, and the two positioning blocks are respectively sleeved inside the two positioning grooves.

[0016] Preferably, the sound basin body is provided with two second card slots, elastic card blocks are clamped inside the two second card slots, dust covers are fixedly connected to the upper ends of the two elastic card blocks, and support blocks are fixedly connected inside the dust covers.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, an internal gear is provided, and when the device is used, the internal gear can be screwed by holding the pull rod. During the rotation of the internal gear, the meshing drives the spur gear to rotate, and during the rotation of the spur gear, the threaded rod connected with the thread is driven to rotate. The threaded rod drives the connecting seat to adjust the placement height, and the connecting seat is connected to the sleeve by a pin. When the position of the threaded rod is adjusted, the sleeve is pulled by the connecting seat to slide and adjust the extension length of the damping rod, which is beneficial to improving the flexibility of the buffer rod when used, and the buffering effect of the buffer rod can be changed according to specific application requirements, which is beneficial to improving the applicability of the device and realizing personalized settings of users.

[0019] In the present invention, by providing a positioning block, when the sound basin body is snap-fitted and installed, the positioning block is aligned and inserted into the positioning groove, and the installation position of the sound basin body is conveniently and quickly positioned before the sound basin body and the damping rod come into contact, which helps to simplify the installation and positioning process. Preliminary positioning can be achieved by simply inserting the positioning block into the positioning groove, and there is no need to spend a lot of time to adjust the position of the sound basin body, which greatly shortens the time required for installation and positioning.

[0020] In the present invention, a sliding block is provided and a first slot is installed under the sound basin body. When the sound basin body is extended into the basin frame body, the first slot squeezes the sliding block to slide outward. When the first slot and the sliding block are on the same horizontal line, the sliding block is driven to slide out and be connected in the first slot under the action of the second spring, so as to clamp and fix the sound basin body. When the sound basin body needs to be disassembled and taken out, the inclined block is pressed downward. When the inclined block is pressed and slides, the inclined surface of the inclined block and the inclined slot fit together. When the inclined block slides downward, the sliding block is pushed to slide toward the side away from the connecting block, and the sliding block is pushed out of the first slot. At this time, the sound basin body can be pulled to be disassembled and taken out. The operation is simple and convenient, which is conducive to improving the convenience of disassembly and assembly of the sound basin body, and there is no need to perform complicated disassembly operations, thus saving the time required for maintenance.

[0021] In the present invention, by providing a first spring and a rubber pad connected to the outer outer surface of the inclined surface block, an anti-slip effect can be achieved during the pressing operation. When the inclined surface block is pressed down, the sliding block extends out of the first slot, and the connecting block loses its clamping limit. The sound basin body is pressed downward, and the sound basin body squeezes the first spring downward to contract. When the sound basin body is released, the first spring releases the force to push the sound basin body upward to bounce up, thereby avoiding the situation where the sound basin body and the surface of the basin frame body fit together, making it difficult to take, which is beneficial to improving the practicability of the device.

[0022] In the present invention, a dust cover is provided and installed in the sound basin body to prevent dust. The accumulation of dust may affect the vibration characteristics of the sound basin body and cause sound distortion. The dust cover can reduce the influence of dust on the sound basin and keep the dust cover clean, thereby making the sound quality clearer. An installation support block is added in the dust cover to enhance its own stability and avoid deformation that is difficult to recover when squeezed. The dust cover is clamped in the second slot by an elastic clamp block. When the dust cover becomes old or damaged, a tool can be used to remove it, thereby avoiding the need to replace the entire sound basin body due to the fixed installation method, thereby saving maintenance costs.

DETAILED DESCRIPTION

[0032] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] See also Figure 1-Figure 8The present invention provides a self-adjusting speaker basin structure, including a basin frame body 11, a magnet 12 is fixedly connected inside the basin frame body 11, an end of the basin frame body 11 close to the magnet 12 is sleeved with a spring 13, an end of the basin frame body 11 close to the magnet 12 is clamped with a sound basin body 14, the magnet 12 is sleeved on the outer surface of the sound basin body 14, three groups of damping rods 15 are fixedly connected to the lower end of the sound basin body 14, the outer surfaces of the three groups of damping rods 15 are all sleeved with sleeves 16, three groups of rectangular blocks 17 are fixedly connected to the lower end of the basin frame body 11, the three groups of rectangular blocks 17 are all rotatably connected with spur gears 18, the three groups of spur gears 18 are all threadedly connected with threaded rods 19, the upper ends of the three groups of threaded rods 19 are all fixedly connected with connecting seats 21, and the three groups of connecting rods 19 are fixedly connected to the upper ends of the three groups of connecting rods 19. The sockets 21 are respectively sleeved inside the three groups of sleeves 16, and the basin frame body 11 is rotatably connected to a driving mechanism. The driving mechanism includes an internal gear 22, which is rotatably connected to the inside of the basin frame body 11. The internal gear 22 is meshed with the three groups of spur gears 18. The lower end of the internal gear 22 is fixedly connected to a pull rod 23. The magnet 12 and the elastic wave 13 are installed in the basin frame body 11 by gluing, and the sound basin body 14 is clamped in the basin frame body 11. The magnet 12 in the basin frame body 11 is usually a permanent magnet (such as a neodymium iron boron magnet), which generates a fixed magnetic field inside the speaker. When the audio current passes through the speaker, the voice coil will be affected by the Ampere force in the magnetic field, causing the voice coil to move. The elastic wave 13 is connected to the sound basin body 14. The sound cone body 14 is the main sound-generating component of the speaker (made of metal material). When the voice coil moves under the action of the magnetic field force, the voice coil will drive the sound cone body 14 to vibrate together. The vibration of the sound cone body 14 will push the surrounding air molecules to generate sound waves. The vibration amplitude and frequency of the sound cone body 14 correspond to the size and frequency of the audio signal, and can convert the input electrical energy into sound energy of different intensities and frequencies, thereby playing a role in raising the sound. Before installing the sound cone body 14, a damping rod 15 is provided on the damping rod 15. Glue is applied to the end, and the sound basin body 14 is aligned and clamped in the basin frame body 11. At this time, the damping rod 15 is glued to the lower end of the sound basin body 14 by glue, and the damping rod 15 is sleeved and slid inside the sleeve 16 to form a buffer rod. By installing three groups of damping rods 15 at the lower end of the sound basin body 14, the respective extension and contraction degrees can be automatically adjusted according to the force changes of the sound basin body 14, so that the force of the sound basin in all directions is more balanced (for example, when one side of the sound basin body 14 is subjected to a larger impact force, the buffer rod close to that side will be compressed more, and the other buffer rods will be adjusted accordingly to maintain the overall balance of the sound basin body 14). It automatically adjusts its own state in real time to make the vibration of the sound basin body 14 more stable, thereby improving the quality of the sound after the speaker is raised.The damping rod 15 slides and contracts in the sleeve 16 to play a buffering role. (As the damping rod 15 is compressed, the rubber structure molecules inside the sleeve 16 become tighter, and the friction and viscosity between the rubber molecules increase with the increase in the degree of compression, so that the extrusion force required for the damping rod 15 in the later stage of being squeezed gradually increases). When the device is used, the inner gear 22 can be screwed by holding the pull rod 23. During the rotation of the inner gear 22, the meshing drives the spur gear 18 to rotate (the spur gear 18 rotates inside the rectangular block 17, and is installed at the bottom of the basin frame body 11 through the rectangular block 17). During the rotation of the spur gear 18, the threaded connection 22 is driven The connected threaded rod 19 rotates, and the threaded rod 19 drives the connection seat 21 to adjust the placement height. The connection seat 21 is sleeved in the sleeve 16 through a pin. When the position of the threaded rod 19 is adjusted, the sleeve 16 is pulled by the connection seat 21 to slide and adjust the extension length of the damping rod 15, which is conducive to improving the flexibility of the buffer rod when using it, and the buffering effect of the buffer rod can be changed according to specific application requirements (for example, in situations where a larger buffering force is required, the extension length of the damping rod 15 can be shortened to make it more compact, thereby increasing the elastic coefficient and providing a stronger buffering effect). It is conducive to improving the applicability of the device and realizing the personalized settings of the user.

[0034] The lower end of the basin frame body 11 is fixedly connected to one end close to the three groups of damping rods 15 with two connecting blocks 24, and the two connecting blocks 24 are both provided with first card slots 25. The lower ends of the two connecting blocks 24 are both fixedly connected with first springs 26. The basin frame body 11 is internally fixedly connected with two second springs 27, and the two second springs 27 are fixedly connected with sliding card blocks 28 on one side close to the connecting block 24. The two sliding card blocks 28 are respectively clamped in the two first card slots 25. The basin frame body 11 is internally slidably connected with two inclined blocks 29, and the outer surfaces of the two inclined blocks 29 are sleeved with rubber pads 31. The two sliding card blocks 28 are both provided with inclined slide grooves 32, and the two inclined blocks 29 are respectively fitted with the two inclined slide grooves 32. The inner surface of the basin frame body 11 is fixedly connected with two second springs 27. There are two rectangular seats 33 fixedly connected, and the two first springs 26 are respectively sleeved inside the two rectangular seats 33. The lower end of the basin frame body 11 is close to one end of the three groups of damping rods 15 and is fixedly connected with two positioning blocks 34. Two positioning grooves 35 are provided inside the basin frame body 11. The two positioning blocks 34 are respectively sleeved inside the two positioning grooves 35. When the sound basin body 14 is clamped and installed, the positioning blocks 34 are aligned and inserted into the positioning grooves 35. Before the sound basin body 14 and the damping rods 15 contact, the installation position of the sound basin body 14 is conveniently and quickly positioned, which is conducive to simplifying the installation positioning process. The positioning blocks 34 only need to be inserted into the positioning grooves 35 to achieve preliminary positioning, and there is no need to spend a lot of time to adjust the position of the sound basin body 14, which greatly shortens the time required for installation and positioning. A first card slot 25 is installed under the sound basin body 14. When the sound basin body 14 extends into the basin frame body 11, the first card slot 25 squeezes the sliding card block 28 to slide outward. When the first card slot 25 and the sliding card block 28 are on the same horizontal line, the sliding card block 28 is driven to slide out and be connected in the first card slot 25 under the action of the second spring 27, so as to clamp and fix the sound basin body 14. When the sound basin body 14 needs to be disassembled and taken out, the inclined block 29 is pressed downward. When the inclined block 29 is pressed to slide, the inclined surface of the inclined block 29 and the inclined slide groove 32 are fitted. When the inclined block 29 slides downward, it pushes the sliding card block 28 to slide to the side away from the connecting block 24, and pushes the sliding card block 28 out of the first card slot 25. At this time, the speaker 10 can be pulled out. The movable sound basin body 14 can be disassembled and taken out, and the operation is simple and convenient, which is conducive to improving the convenience of disassembly and assembly of the sound basin body 14, and there is no need to perform complicated disassembly operations, saving the time required for maintenance. The outer sleeve of the inclined block 29 is connected to a rubber pad 31, which can play an anti-slip role during the pressing operation. When the inclined block 29 is pressed down, the sliding block 28 extends from the first slot 25. At this time, the connecting block 24 loses the clamping limit, and the sound basin body 14 is pressed downward. The sound basin body 14 squeezes the first spring 26 downward to contract. When the sound basin body 14 is released, the first spring 26 releases the force to push the sound basin body 14 upward to bounce up, avoiding the situation where the sound basin body 14 and the basin frame body 11 are in contact with the surface, making it difficult to take, which is conducive to improving the practicability of the device.

[0035] The sound basin body 14 is provided with two second slots 36, and elastic blocks 37 are clamped inside the two second slots 36. The upper ends of the two elastic blocks 37 are fixedly connected with dust covers 38, and the dust covers 38 are fixedly connected with support blocks 39. The dust covers 38 are installed in the sound basin body 14 to prevent dust. The accumulation of dust may affect the vibration characteristics of the sound basin body 14 and cause sound distortion. The dust covers 38 can reduce the impact of dust on the sound basin and keep the dust covers 38 clean, thereby making the sound quality clearer. The support blocks 39 are added to the dust covers 38 to enhance their own stability and avoid deformation that is difficult to recover when squeezed. The dust covers 38 are clamped in the second slots 36 by the elastic blocks 37. When the dust covers 38 are old or damaged, tools can be used to remove them, thereby avoiding the need to replace the entire sound basin body 14 due to the fixed installation method, thereby saving maintenance costs.

[0036] Working principle:

[0037] The first step is to install the magnet 12 and the elastic wave 13 in the basin frame body 11 by gluing, and clamp the sound basin body 14 in the basin frame body 11. The magnet 12 in the basin frame body 11 is usually a permanent magnet (such as a neodymium iron boron magnet), which generates a fixed magnetic field inside the speaker. When the audio current passes through the speaker, the voice coil will be affected by the Ampere force in the magnetic field, causing the voice coil to move. The elastic wave 13 is connected between the sound basin body 14 and the basin frame body 11 of the speaker, and plays a role in keeping the voice coil in the center position of the magnetic field, ensuring that the voice coil will not shift or tilt during the movement, which helps to improve the performance and reliability of the speaker and reduce distortion and noise. The sound basin body 14 is the main sound-generating component of the speaker (made of metal material When the voice coil moves under the action of the magnetic field force, the voice coil will drive the sound basin body 14 to vibrate together. The vibration of the sound basin body 14 will push the surrounding air molecules to generate sound waves. The vibration amplitude and frequency of the sound basin body 14 correspond to the size and frequency of the audio signal, and can convert the input electrical energy into sound energy of different intensities and frequencies, thereby playing a role in raising the sound. Before installing the sound basin body 14, glue is applied to the upper end of the damping rod 15, and the sound basin body 14 is aligned and clamped in the basin frame body 11. At this time, the damping rod 15 is adhered to the lower end of the sound basin body 14 by glue, and the damping rod 15 is sleeved and slid inside the sleeve 16 to form a buffer rod. By installing three groups of damping rods 15 at the lower end of the sound basin body 14, the damping rod 15 can be adjusted according to the sound basin body 1 4, automatically adjusts the respective extension and contraction degrees, so that the force on the sound basin in all directions is more balanced (for example, when one side of the sound basin body 14 is subjected to a large impact force, the buffer rod close to this side will be compressed more, and other buffer rods will be adjusted accordingly to maintain the overall balance of the sound basin body 14) automatically adjusts its own state in real time to make the vibration of the sound basin body 14 more stable, thereby improving the quality of the sound after the sound is raised. The damping rod 15 slides and contracts in the sleeve 16 to play a buffering role. (As the damping rod 15 is compressed, the rubber structure molecules inside the sleeve 16 will become more compact, and the friction and viscosity between the rubber molecules will increase with the increase in the degree of compression, so that the extrusion force required for the damping rod 15 in the later stage of being squeezed gradually increases. ), when the device is in use, the inner gear 22 can be screwed by holding the pull rod 23. During the rotation of the inner gear 22, the meshing drives the spur gear 18 to rotate (the spur gear 18 rotates inside the rectangular block 17, and is installed at the bottom of the basin frame body 11 through the rectangular block 17). During the rotation of the spur gear 18, the threaded rod 19 connected by the thread is driven to rotate, and the connection seat 21 is driven by the threaded rod 19 to adjust the placement height. The connection seat 21 is sleeved in the sleeve 16 through a pin. When the position of the threaded rod 19 is adjusted, the sleeve 16 is pulled by the connection seat 21 to slide and adjust the extension length of the damping rod 15, which is beneficial to improve the flexibility of the buffer rod when used, and the buffering effect of the buffer rod can be changed according to specific application requirements (for example, in occasions where a larger buffering force is required,The extension length of the damping rod 15 can be shortened to make it more compact, thereby increasing the elastic coefficient and providing a stronger buffering effect, which is beneficial to improving the applicability of the device and realizing the personalized setting of the user.

[0038] In the second step, when the sound basin body 14 is snap-fitted and installed, the positioning block 34 is aligned and inserted into the positioning groove 35. Before the sound basin body 14 and the damping rod 15 contact, the installation position of the sound basin body 14 is conveniently and quickly positioned, which is conducive to simplifying the installation and positioning process. The positioning block 34 only needs to be inserted into the positioning groove 35 to achieve preliminary positioning, and there is no need to spend a lot of time to adjust the position of the sound basin body 14, which greatly shortens the time required for installation and positioning. A first slot 25 is installed under the sound basin body 14. When the sound basin body 14 extends into the basin frame body 11, the first slot 25 squeezes the sliding block 28 to slide outward. When the first slot 25 and the sliding block 28 are on the same horizontal line, the sliding block 28 is driven to slide out and snap into the first slot 25 under the action of the second spring 27, so as to clamp and fix the sound basin body 14. When the sound basin body 14 needs to be disassembled and taken out, the inclined block 29 is pressed downward. When the inclined block 29 is pressed to slide, the inclined block The inclined surface of 29 fits with the inclined slide groove 32. When the inclined block 29 slides downward, it pushes the sliding block 28 to slide toward the side away from the connecting block 24, and pushes the sliding block 28 out of the first slot 25. At this time, the sound basin body 14 can be pulled to disassemble and take it out. The operation is simple and convenient, which is conducive to improving the convenience of disassembly and assembly of the sound basin body 14, and there is no need to perform complicated disassembly operations, saving the time required for maintenance. The outer sleeve of the inclined block 29 is connected with a rubber pad 31, which can play an anti-slip role during the pressing operation. When the inclined block 29 is pressed down, the sliding block 28 extends out of the first slot 25. At this time, the connecting block 24 loses the clamping limit, and the sound basin body 14 is pressed downward. The sound basin body 14 squeezes the first spring 26 downward to contract. When the sound basin body 14 is released, the first spring 26 releases the force to push the sound basin body 14 upward to bounce up, avoiding the situation where the sound basin body 14 and the basin frame body 11 are fitted together to make it difficult to take, which is conducive to improving the practicality of the device.

[0039] The third step is to install a dust cover 38 in the sound basin body 14 to prevent dust. The accumulation of dust may affect the vibration characteristics of the sound basin body 14 and cause sound distortion. The dust cover 38 can reduce the impact of dust on the sound basin and keep the dust cover 38 clean, thereby making the sound quality clearer. By adding an installation support block 39 in the dust cover 38, its own stability is enhanced to avoid deformation and difficulty in recovery when squeezed. The dust cover 38 is clamped in the second clamping slot 36 by an elastic clamping block 37. When the dust cover 38 becomes old or damaged, a tool can be used to remove it to avoid the need to replace the entire sound basin body 14 due to the fixed installation method, thereby saving maintenance costs.
