Abstract
Description
Technical Field
[0001] This invention relates to the field of audio equipment, and more specifically, to a shockproof audio system and its usage method. Background Technology
[0002] As a commonly used audio playback device, speakers are widely used in various scenarios such as homes, cars, and outdoors. In actual use, speakers are inevitably affected by external vibrations, such as road bumps in a car, collisions when used outdoors, and accidental touches in a home environment.
[0003] Most existing audio systems have relatively simple shock-absorbing structures, typically using only a single elastic pad or spring for vibration damping. This provides limited damping and lacks the ability to adaptively adjust to different vibration levels. When subjected to significant vibrations, the internal speakers are prone to displacement and damage, affecting not only audio playback quality but also shortening the system's lifespan.
[0004] To address the shortcomings of the existing technology, this invention proposes a shockproof speaker that combines active buffering with passive vibration reduction through multiple shockproof structures and a vibration sensing and early warning mechanism. This effectively improves the speaker's shockproof performance, protects the internal speakers, and extends the device's lifespan. Summary of the Invention
[0005] To overcome the above shortcomings, the present invention provides a shockproof speaker and its usage method, aiming to improve the problems of poor shockproof effect, lack of vibration warning and inability to adaptively adjust in the prior art.
[0006] This invention is implemented as follows: The present invention provides a shockproof speaker, comprising a speaker body with a speaker base, the speaker base comprising a magnetic ball receiving base, a magnetic sleeve and an elastic part; the speaker body is further provided with a sensing part, and the outer wall of the magnetic sleeve is provided with a magnetizing strip.
[0007] The specific structure is as follows: Magnetic ball holder: It has a spherical structure with a radially arranged storage groove. The speaker slides along the storage groove through the magnetic shielding base. The magnetic ball holder has two sets of buffer air chambers, which are respectively located at both ends of the magnetic shielding base. When vibrating along the extension direction of the storage groove, the magnetic shielding base compresses the gas in the buffer air chambers to achieve a buffering and shock absorption effect. The magnetic ball holder is connected to the inner wall of the speaker body through an elastic part. When vibrating, the elastic part first absorbs the vibration force through its own deformation and then transmits it to the magnetic ball holder.
[0008] Magnetic sleeve: A cylindrical structure with magnetic force, used to house the magnetic ball holder. The inner wall of the magnetic sleeve has the same magnetism as the outer wall of the magnetic ball holder. Through the repulsive force of the magnetism, the magnetic ball holder and the inner wall of the magnetic sleeve do not come into contact, and the magnetic ball holder is cushioned based on this magnetic effect.
[0009] Magnetic shielding base: It is a cylindrical structure formed by magnetic shielding sheets, with one end open and the other end closed. The loudspeaker is housed inside the magnetic shielding base and fixed to the open end of the magnetic shielding base. Its outer end is provided with a sliding protrusion. The sliding protrusion slides in the buffer air cavity in a sealed manner. When vibrating, the sliding protrusion achieves buffering by compressing the gas in the buffer air cavity.
[0010] Buffer air chamber: A buffer port is provided at the end away from the sliding protrusion. The inner diameter of the buffer port is smaller than the area of the sliding protrusion. When vibration occurs, the sliding protrusion squeezes the gas inside the buffer air chamber and discharges it through the buffer port, further reducing the buffering force. The sliding protrusion is restored to its initial state by a reset component, which is a spring or a magnetic component that attracts each other. An electrically controlled sealing component is provided on the inner wall of the buffer port. The sealing component is a solenoid valve or a cover plate structure controlled by a drive component.
[0011] Elastic part: includes a connecting ring and elastic rods; the connecting ring is fixedly installed on the inner wall of the speaker body; the elastic rods are in multiple sets, arranged in a ring at one end of the connecting ring, and the other end of the elastic rods is fixed to the end of the magnetic isolation base, and the speaker sound output position is coaxial with the connecting ring.
[0012] The sensing unit includes a sensing ball and a magnetic touch ball. The sensing ball has a spherical inner cavity, and its inner wall is composed of multiple sets of arc-shaped magnetic sheets, on which a pressure sensing part is provided. The external magnetic field of the magnetic touch ball and the internal magnetic field of the sensing ball are magnetically identical. In the initial state, the magnetic touch ball is suspended at the center of the sensing ball. In the vibration state, after the magnetic touch ball collides with the corresponding arc-shaped magnetic sheet, the pressure sensing part on the arc-shaped magnetic sheet senses the pressure and controls the sealing component to open the buffer port through the controller. In the initial state, the distance between the magnetic touch ball and the sensing ball is less than the distance between the magnetic ball storage base and the magnetic sleeve. When vibration occurs, the sensing part is triggered first and then feedback is given to the sealing component to prevent vibration in advance.
[0013] Magnetizing strips: Two sets are configured, symmetrically distributed at the outer end of the magnetic sleeve, and the magnetizing strips rotate circumferentially along the outer end of the magnetic sleeve; by changing the position of the magnetizing strips, the magnetic force in the radial direction of the magnetic sleeve is increased. That is, when the sensing part is triggered and the next vibration position is sensed, the magnetizing strips move to the radial position of the magnetic sleeve in advance, thereby enhancing the radial magnetic force of the magnetic sleeve on the magnetic ball receiving seat and further buffering the vibration of the magnetic ball receiving seat; the magnetizing strips are driven to rotate by an electric rotating component, and the controller and the electric rotating component are electrically connected.
[0014] This invention also discloses a method for using a shockproof sound system, comprising the following steps: S1. In the initial state, the solenoid valve closes the buffer port, the gas in the buffer air chamber cannot be discharged, the sliding protrusion is in the middle position under the action of the spring, the air pressure in the buffer air chambers at both ends is equal, and the speaker works stably; the magnetic touch ball is suspended in the center of the induction ball, the magnetizing strip is in the initial position, and a stable repulsive distance is maintained between the magnetic sleeve and the magnetic ball storage seat.
[0015] S2. When the speaker is subjected to external vibration, the vibration is first transmitted to the sensing part. The magnetic contact ball deviates from the center position under the action of vibration and collides with the corresponding arc-shaped magnetic sheet. The pressure sensor on the arc-shaped magnetic sheet senses the pressure signal and transmits the signal to the controller. After receiving the signal, the controller immediately controls the solenoid valve to open the buffer port. At the same time, it determines the vibration direction based on the signal from the pressure sensor and controls the electric rotating part to drive the magnetizing strip to rotate to the corresponding radial position to enhance the magnetic repulsion in that direction.
[0016] S3. The vibration continues to be transmitted to the speaker mount, causing the spring rod in the elastic part to bend and deform, absorbing part of the vibration force. The remaining vibration force is transmitted to the magnetic ball receiving seat, which undergoes a slight displacement under the repulsive force of the magnetic sleeve, achieving a second layer of buffering. At the same time, the speaker drives the magnetic isolation seat to slide along the receiving groove. The sliding protrusion on the magnetic isolation seat compresses the buffer air chamber at the corresponding end, and the gas in the buffer air chamber is slowly discharged through the buffer port. During the gas discharge process, the vibration force is continuously consumed, achieving a third layer of buffering and also buffering the vibration force along the direction of the receiving groove. After the vibration disappears, the spring drives the sliding protrusion to reset, the solenoid valve closes the buffer port, the magnetizing strip returns to the initial position, and the equipment returns to its initial state. The beneficial effects of this invention are: 1. Multiple shock absorption and excellent buffering effect: This invention adopts a triple shock absorption structure of elastic buffering, magnetic repulsion buffering and air pressure buffering. The elastic part first absorbs part of the vibration force, the repulsion between the magnetic sleeve and the magnetic ball storage base avoids the transmission of vibration caused by direct contact, and the buffer air chamber further consumes the vibration force through gas compression. The triple combination effectively improves the shock absorption effect and avoids damage to the speaker due to vibration.
[0017] 2. Early warning and active buffering: The sensor unit is set up, and the magnetic touch ball and the levitation ball work together to quickly trigger the initial vibration, control the sealing part to open the buffer port in advance, prepare for buffering, and achieve active shock absorption. Compared with the existing passive shock absorption method, the reliability of shock absorption is greatly improved.
[0018] 3. Adaptive adjustment to fit different vibration scenarios: The magnetic strip can adjust its position by rotating according to the vibration direction predicted by the sensing unit, thereby enhancing the magnetic repulsion in the corresponding direction and achieving targeted buffering; the gas discharge speed of the buffer air chamber can be controlled by the buffer port to adapt to vibrations of different intensities and improve the versatility of the equipment.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example Example 1, referring to Figures 1-5 This embodiment provides a shockproof speaker, including a speaker body and a speaker base 1 and a sensing part 2 disposed in the speaker body (which is prior art and its shape is not limited in this embodiment), and a magnetizing strip 3 disposed on the speaker base 1.
[0024] The specific structure of the speaker base 1 is as follows: The speaker base 1 includes a magnetic ball storage base 10, a magnetic isolation base 11, a magnetic sleeve 12, and an elastic part 13.
[0025] Reference Figure 3 and Figure 4 The magnetic ball storage base 10 adopts a spherical structure and is made of permanent magnet material. A non-penetrating storage groove is formed radially within the groove, the size of which is adapted to the magnetic shielding base 11, allowing the magnetic shielding base 11 to slide along the groove. Furthermore, inside the magnetic ball storage base 10, a set of buffer air chambers 100 are respectively provided at both ends of the storage groove. The buffer air chambers 100 are cylindrical cavities located within the magnetic ball storage base 10, and their inner walls are made of a sealing material to ensure no gas leakage.
[0026] Reference Figure 3 and Figure 4 The magnetic shielding base 11 is formed by stamping a magnetic shielding alloy sheet. It effectively isolates magnetic interference from the speaker, ensuring optimal audio playback. Its structure is a cylindrical shape with one open end and one closed end. The open end is used to fix the speaker, which is bolted to the open end of the magnetic shielding base 11. The closed end faces the inside of the receiving groove. An integrally formed sliding protrusion 110 is formed on the outer side of the closed end of the magnetic shielding base 11. The sliding protrusion 110 has an L-shaped structure, and its horizontal outer diameter matches the inner diameter of the buffer air cavity 100. A sealing ring is fitted onto the outer wall of the sliding protrusion 110 to achieve a sealed sliding fit with the buffer air cavity 100.
[0027] In some embodiments, a reset member is connected to the end of the sliding protrusion 110 away from the magnetic isolation base 11. In this embodiment, the reset member is a spring. One end of the spring is fixed to the end of the sliding protrusion 110, and the other end is fixed to the bottom of the buffer air chamber 100. When the sliding protrusion 110 squeezes the gas in the buffer air chamber 100, the vibration disappears after the gas is compressed and the vibration is buffered. The spring resets and drives the sliding protrusion 110 back to the initial position.
[0028] Reference Figure 3 and Figure 4 The buffer air chamber 100 is provided with a buffer port 1000 at the end away from the sliding protrusion 110. The buffer port 1000 is a circular through hole with an inner diameter smaller than the cross-sectional area of the sliding protrusion 110. This ensures that when the sliding protrusion 110 compresses the gas, the gas can only be slowly discharged through the buffer port 1000, achieving continuous small-amplitude buffering. Compared with the method without a buffer port 1000, the buffer path is longer and the gas is slowly discharged after compression, which reduces the buffer gradient and provides smooth buffering.
[0029] In some embodiments, an electrically controlled sealing component is installed on the inner wall of the buffer port 1000. In this embodiment, the sealing component is a solenoid valve, which is electrically connected to a controller, and its opening and closing state is controlled by the controller. Initially, the solenoid valve is closed, preventing the gas in the buffer chamber 100 from escaping. At this time, the air pressure in the buffer chambers 100 at both ends of the sliding protrusion 110 is equal, stabilizing the position of the sliding protrusion 110 and preventing the speaker from shaking during normal operation, thus ensuring playback stability. When vibration occurs, it can provide small-scale buffering. When the vibration intensity increases, the buffer port 1000 opens to accommodate strong vibrations.
[0030] In other embodiments, the sealing element may also employ a cover plate structure controlled by a motor. For example, the output end of the motor (drive unit) is provided with a mounting base, the motor and controller are electrically connected, and the cover plate is disposed at the bottom of both ends of the mounting base. By rotating the motor, the mounting base is rotated, thereby removing the cover plate from the buffer port 1000. Preferably, to ensure sealing, a sealing layer is provided at the bottom of the cover plate.
[0031] Reference Figure 3 and Figure 4 The magnetic sleeve 12 is a cylindrical structure made of permanent magnet material. The magnetism of its inner wall is the same as that of the outer wall of the magnetic ball holder 10, both being N poles (or both being S poles). Through the combined action of magnetic repulsion and elastic part 13, the magnetic ball holder 10 is suspended inside the magnetic sleeve 12, and the two do not come into contact, thereby preventing vibration from being directly transmitted to the magnetic ball holder 10 through the magnetic sleeve 12.
[0032] Furthermore, refer to Figures 2-4 Two sets of magnetizing strips 3 are installed on the outer wall of the magnetic sleeve 12. The two sets of magnetizing strips 3 are symmetrically distributed at both ends of the magnetic sleeve 12. The magnetizing strips 3 are made of high magnetic material or electromagnets (the magnetic force can be flexibly adjusted, and the buffer force can be adjusted according to the vibration intensity, and the electromagnets are electrically connected to the controller). An electric rotating component (a micro stepper motor is used in this embodiment) is connected to its bottom. The electric rotating component is fixed to the outer wall of the magnetic sleeve 12 and is electrically connected to the controller. The controller can control the electric rotating component to drive the magnetizing strips 3 to rotate around the circumference of the magnetic sleeve 12, thereby changing the position of the magnetizing strips 3 and enhancing the magnetic repulsion force of the magnetic sleeve 12 in the corresponding radial direction.
[0033] Reference Figures 2-4The elastic part 13 includes a connecting ring 130 and an elastic rod 131. The connecting ring 130 is a metal ring, which is fixed to the inner wall of the speaker body by bolts and is coaxially arranged with the sound output direction of the speaker. The elastic rod 131 is an elastic metal rod, with multiple rods evenly distributed in a ring at the end of the connecting ring 130 near the speaker. One end of the elastic rod 131 is welded to the connecting ring 130 and the other end is welded to the open end of the magnetic shielding base 11. When the speaker is vibrated, the elastic rod 131 absorbs part of the vibration force through its own bending deformation and then transmits the remaining vibration force to the magnetic ball receiving base 10, thus achieving the first layer of buffering.
[0034] In other embodiments, reference is made to... Figure 5 The specific structure of the sensing unit 2 is as follows: The sensing unit 2 is located inside the speaker body, preferably in a corner position, away from the speaker mount 1, to avoid the vibration of the speaker during operation from accidentally triggering the sensing unit 2. The sensing unit 2 includes a sensing ball 20 and a magnetic touch ball 21.
[0035] Reference Figure 5 The sensing ball 20 is a spherical shell with a spherical inner cavity inside. Multiple sets of arc-shaped magnetic sheets 200, such as six sets, are fixed to the inner wall of the inner cavity. The six sets of arc-shaped magnetic sheets 200 are evenly distributed on the inner wall of the sensing ball 20, specifically arranged as follows: one in each of the six directions (front, back, left, right, up, and down). Each arc-shaped magnetic sheet 200 has a pressure sensor (i.e., a pressure sensing part) on its inner surface. The pressure sensor is electrically connected to the controller and can transmit the sensed pressure signal to the controller.
[0036] Furthermore, the magnetic touch ball 21 has a spherical structure and is made of permanent magnet material. Its external magnetic field is the same as the magnetic field of the arc-shaped magnetic sheet 200 on the inner wall of the induction ball 20. Through the magnetic repulsion, the magnetic touch ball 21 is suspended in the center of the inner cavity of the induction ball 20 (the magnetic force of the arc-shaped magnetic sheet 200 at the bottom is greater than that of the other arc-shaped magnetic sheets 200 because it needs to overcome the gravity of the magnetic touch ball 21). In the initial state, the distance between the magnetic touch ball 21 and the arc-shaped magnetic sheet 200 on the inner wall of the sensing ball 20 is smaller than the distance between the magnetic ball receiving base 10 and the inner wall of the magnetic sleeve 12. For example, the distance between the magnetic touch ball 21 and the arc-shaped magnetic sheet 200 on the inner wall of the sensing ball 20 is 5mm, while the distance between the magnetic ball receiving base 10 and the inner wall of the magnetic sleeve 12 is 10mm. This ensures that when a strong vibration occurs, the magnetic touch ball 21 is first affected by the strong vibration, deviates from the center position, and collides with the corresponding arc-shaped magnetic sheet 200. After receiving the signal, the controller adjusts the position of the magnetizing strip 3 based on the feedback vibration orientation information, so that after the magnetizing strip 3 moves, the magnetic orientation of the magnetizing strip 3 is the same as the vibration orientation, which can be adjusted in real time.
[0037] When there is a slight vibration, the magnetic ball 21 will not collide with the arc-shaped magnetic sheet 200. The magnetic ball receiving seat 10 achieves the buffering of the slight vibration under the action of the elastic part 13, the magnetic sleeve 12 and the gas in the compression buffer air chamber 100.
[0038] When there is strong vibration, the buffering effect is further enhanced by opening the buffer port 1000 and moving the magnetizing strip 3 (when it is an electromagnet, it is adjusted by magnetic force) on the basis of the weak vibration buffer.
[0039] The working process is as follows: In the initial state, the solenoid valve closes the buffer port 1000, the gas in the buffer air chamber 100 cannot be discharged, the sliding protrusion 110 is in the middle position under the action of the spring, the air pressure in the two buffer air chambers 100 is equal, and the speaker works stably; the magnetic touch ball 21 is suspended in the center of the induction ball 20, the magnetizing strip 3 is in the initial position, and the magnetic sleeve 12 and the magnetic ball storage seat 10 maintain a stable repulsive distance.
[0040] When the speaker is subjected to external vibration, the vibration is first transmitted to the sensing unit 2. The magnetic contact ball 21 deviates from the center position under the action of vibration and collides with the corresponding arc-shaped magnetic sheet 200. The pressure sensor on the arc-shaped magnetic sheet 200 senses the pressure signal and transmits the signal to the controller. After receiving the signal, the controller immediately controls the solenoid valve to open the buffer port 1000. At the same time, it determines the vibration direction based on the signal from the pressure sensor and controls the electric rotating component to drive the magnetizing strip 3 to rotate to the corresponding radial position to enhance the magnetic repulsion in that direction.
[0041] The vibration continues to be transmitted to the speaker base 1, and the elastic rod 131 of the elastic part 13 bends and deforms, absorbing part of the vibration force; the remaining vibration force is transmitted to the magnetic ball receiving base 10, and the magnetic ball receiving base 10 produces a small displacement under the repulsive force of the magnetic sleeve 12, realizing the second layer of buffering; at the same time, the speaker drives the magnetic isolation base 11 to slide along the receiving groove, and the sliding protrusion 110 on the magnetic isolation base 11 squeezes the corresponding end of the buffer air chamber 100. The gas in the buffer air chamber 100 is slowly discharged through the buffer port 1000. During the gas discharge process, the vibration force is continuously consumed, realizing the third layer of buffering and also buffering the vibration force along the direction of the receiving groove; after the vibration disappears, the spring drives the sliding protrusion 110 to reset, the solenoid valve closes the buffer port 1000, the magnetizing strip 3 returns to the initial position, and the equipment returns to the initial state.
[0042] Example 2 differs from Example 1 in that the reset component uses a magnetically attracted component. Specifically, a permanent magnet is fixed at the end of the sliding protrusion 110, and a permanent magnet that is magnetically attracted to the permanent magnet is fixed at the bottom of the buffer air cavity 100. The sliding protrusion 110 is reset by the attraction between the two permanent magnets. The elastic rod 131 is made of rubber and absorbs vibration force through the elastic deformation of the rubber. The rest of the structure is the same as in Example 1, and its working process is also basically the same as in Example 1, which can also achieve excellent shock absorption effect.
[0043] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
