[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] As Figures 1 to 5 shown, this is the first embodiment of the present invention, providing a low-frequency vibration type in-vehicle audio. The device includes a housing assembly 1, an abutting assembly 2 provided on the outer surface of the housing assembly 1. The housing assembly 1 is provided with an outer shell 101. A speaker 102 is installed on the inner wall of the outer shell 101. Positioning blocks 103 are installed on both sides of the outer wall of the outer shell 101, and the positioning blocks 103 are used to position the installation position of the housing assembly 1 to prevent the position from rotating during use and improve the stability of use;

[0035] The abutting component 2 is provided with four arc-shaped members 202 located outside the outer shell 101. An arc-shaped groove 201 is formed inside the outer shell 101. The inner wall of the arc-shaped groove 201 is movably connected to the four arc-shaped members 202. A connecting column 203 is installed at the bottom of the arc-shaped member 202. The bottom of the connecting column 203 extends into the arc-shaped groove 201 and the outer shell 101 and is installed with a disc 204. An installation block 205 is connected to the outside of the disc 204. The outer surface of the installation block 205 is sleeved with the inner wall of the outer shell 101. A limiting ring 206 is sleeved inside the installation block 205. The outside of the limiting ring 206 is connected to the inner wall of the outer shell 101. A first spring 207 is sleeved on the outer surface of the limiting ring 206. The installation block 205 is elastically connected to the outer shell 101 through the first spring 207. An inclined groove 208 is formed inside the disc 204;

[0036] When the fixing of the disc 204 is released, at this time, since the first spring 207 is in a stretched state, a backward pulling force will be applied to the installation block 205, driving the installation block 205 to move on the outer surface of the limiting ring 206 to move it to a suitable position. At the same time, the installation block 205 will drive the disc 204, the connecting column 203 and the arc-shaped member 202 to move. And as the arc-shaped member 202 moves, it drives the arc-shaped member 202 to present an arched shape, and then the outer walls of the four arc-shaped members 202 are used to support the installation groove of the car audio, so as to prevent it from moving in position;

[0037] The stabilizing component 5 is arranged on the back of the abutting component 2. The stabilizing component 5 realizes the support of the housing component 1 through four groups of support frames 502 arranged at equal intervals. The stabilizing component 5 includes an inclined plate 501. The outer wall of the inclined plate 501 is sleeved with the inner wall of the outer shell 101. The outer surface of the inclined plate 501 is connected to the outer wall of the disc 204. The inner wall of the support frame 502 is sleeved with the outer surface of the inclined plate 501. The support frame 502 extends to the outside of the outer shell 101. The end of the support frame 502 is a rubber block. The support frame 502 is elastically connected to the outer shell 101 through a spring;

[0038] As the disc 204 rotates, the inclined plate 501 is driven to move through the disc 204, so that the support frame 502 is extruded to move outward. When the housing component 1 is installed into the audio installation groove, at this time, the support frame 502 will expand from the inside of the door frame, so that the rubber block at its end is closely attached to the inner wall of the frame cavity, and the housing component 1 is clamped inside the door frame, preventing it from moving out of the frame interior. At the same time, the rubber block installed at the end makes a buffering effect when the housing component 1 moves back and forth, so as to improve its service life;

[0039] Thus, when the operator installs, the deformation generated by the four arc-shaped members 202 is used to perform snap-in installation on installation grooves of different sizes, so as to improve the installation stability of the housing component 1;

[0040] Embodiment 2

[0041] like Figures 5 to 9 As shown, this embodiment includes all the features of the embodiment 1, and the distinguishing technical feature is that the trigger mechanism 3 is arranged on the inner side of the abutment assembly 2, and the trigger mechanism 3 is provided with a movable disk 301, the outer surface of the movable disk 301 is sleeved with the inner wall of the housing 101, and the inner cavity of the movable disk 301 is sleeved with a pressing block 302, the outer side of the pressing block 302 extends into the inner cavity of the mounting block 205, and the inner side of the pressing block 302 is connected to a pressing rod 303, and the inner side of the pressing rod 303 extends to the outside of the movable disk 301, and the pressing rod 303 is connected to the inner side of the movable disk 301. The outer surface of the rod 303 is sleeved with a second spring 304, and the second spring 304 is elastically connected to the movable disk 301 through the pressure block 302. The inner wall of the housing 101 is connected to a fixed column 305, and the outer surface of the fixed column 305 is sleeved with a connecting plate 306. The outer surface of the connecting plate 306 contacts the end of the pressure rod 303. The interior of the housing 101 is provided with a card slot 308 located on both sides of the movable disk 301, and both sides of the movable disk 301 are provided with a ratchet 307 located inside the card slot 308;

[0042] The elastic force of the spring 1 207 drives the disc 204 and the mounting block 205 to move, and then the mounting block 205 drives the pressing block 302 and the movable disc 301 to move, and the inclined slot 208 is moved to the outside of the positive inclined block 403;

[0043] By setting the housing assembly 1, the vibration generated by its own low frequency, the shaking of the car when driving and the violent collision when closing the door are continuously damped by the arc-shaped member 202 and the spring 1 207.

[0044] Since the spring 1 207 will become fatigued after long-term use, the connection between the arc-shaped member 202 and the speaker will be unstable. After a period of use, the spring 1 207 will become elastically fatigued, and the deformed arc-shaped member 202 will gradually return to its original position, thereby driving the mounting block 205 to move back, so as to squeeze the pressing block 302. Due to the design of the pawl 307 and the slot 308, the movable disk 301 cannot be driven to return to its original position, so that the pressing block 302 is squeezed into the movable disk 301, and then the pressing block 302 drives the pressure rod 303 to move downward, squeezing the connecting plate 306, thereby triggering the impact structure 4 through the connecting plate 306. The impact of the impact structure 4 strengthens the deformation amplitude and elastic strength of the arc-shaped member 202.

[0045] The impact structure 4 is provided with a chute 401 which is opened inside the outer shell 101 and located outside the trigger mechanism 3. An installation rod 402 is connected inside the chute 401. An inclined block 403 is sleeved on the outer surface of the installation rod 402. The end of the inclined block 403 is in contact with the back surface of the disc 204. A spherical ball 405 is arranged in the inner cavity of the chute 401. The chute 401 is movably connected with an installation plate 406 located below the connecting plate 306. The bottom of the installation plate 406 is sleeved with the bottom of the connecting plate 306. An electromagnet 407 is installed on the top of the installation plate 406. The top of the electromagnet 407 extends to the bottom of the spherical ball 405 for magnetic connection. An inclined opening 409 is opened inside the outer shell 101 and located outside the installation block 205. A clamping block 408 is sleeved inside the inclined opening 409. The outside of the clamping block 408 is connected with the outside of the installation block 205;

[0046] When the first spring 207 shows elastic fatigue, it drives the arc-shaped part 202 to reset at this time, and at the same time drives the installation block 205 to squeeze the pressing block 302. Through the pressing rod 303 and the connecting plate 306, it drives the installation plate 406 and the electromagnet 407 to move downward. As the electromagnet 407 moves, the adsorption of the spherical ball 405 will be released, resulting in its active state. As the car door is opened, the spherical ball 405 inside the housing assembly 1 moves to the farthest position of the inclined block 403 due to inertia. Then when the door is closed, the inertial movement of the spherical ball 405 at this time causes the spherical ball 405 to impact the inclined block 403, driving the inclined block 403 to squeeze the disc 204. Then the inclined groove 208 drives the disc 204 to move. At this time, the arch amplitude of the arc-shaped part 202 increases, and then it re-squeezes the inner wall of the sound installation groove. Through the impact on the inclined block 403, it drives the pressing block 302 to move back into the inner cavity of the installation block 205, resetting the trigger mechanism 3, and driving the whole movable disc 301 and the disc 204 to move through the impact force, so that the clamping block 408 on the installation block 205 is moved to the next inclined opening 409, strengthening the clamping effect between the arc-shaped part 202 and the sound installation groove. Thus, by strengthening the deformation degree of the arc-shaped part 202, the elastic fatigue caused by the long-term use of the arc-shaped part 202 and the first spring 207 is avoided, which affects the shock absorption effect of the housing assembly 1, preventing the sound quality of the low-frequency vibration in-vehicle audio from being affected due to shaking. At the same time, the arc-shaped part 202 continuously shocks the housing assembly 1 to prevent the internal components from being damaged due to long-term vibration;

[0047] Embodiment 3

[0048] As Figure 10 and Figure 11As shown in the figure, this embodiment includes all the technical features of Embodiment 1. The distinguishing technical feature is that a sealing structure 6 is provided on the front of the housing assembly 1. The sealing structure 6 realizes the fitting to the vehicle frame through the installation of the housing assembly 1. The sealing structure 6 includes a movable block 601. The outer surface of the movable block 601 is sleeved with the inner wall of the outer shell 101. A moving plate 602 located in the inner cavity of the housing assembly 1 is installed inside the movable block 601. An air cushion 603 is connected to the bottom of the moving plate 602. A sealing ring 604 located on the top of the movable block 601 is installed on the outer surface of the air cushion 603. The inner side of the sealing ring 604 extends outside the outer shell 101;

[0049] When installing the housing assembly 1 in the door frame, at this time, the housing assembly 1 is buckled into the internal sound installation groove of the vehicle frame, so that the movable block 601 is extruded by the outer wall of the vehicle frame, driving the movable block 601 to move into the inner part of the outer shell 101. Furthermore, the movable block 601 drives the moving plate 602 to extrude the air cushion 603, pushing the sealing ring 604 on the air cushion 603 inwards, making the sealing ring 604 fit with the outer wall of the vehicle frame, so as to achieve a sealing effect, avoiding water leakage in the inner cavity of the vehicle frame due to the sound. At the same time, because the sealing ring 604 has good elasticity, the housing assembly 1 has a good limiting effect and a good buffering effect, improving the service life of the sound;

[0050] A positioning rod 605 is installed on the inner wall of the moving plate 602. The inner side of the positioning rod 605 penetrates through the outer shell 101 and extends to the hinge center of the arc-shaped member 202 and extends into the inside of the disc 204.

[0051] When installing the housing assembly 1, the housing assembly 1 is clamped into the installation groove. The outer wall of the vehicle frame will extrude the movable block 601. Furthermore, the moving plate 602 drives the positioning rod 605 to move backward, and the positioning rod 605 moves out of the inside of the disc 204, releasing the fixation of the disc 204. Through the elastic force of the first spring 207, the arc-shaped member 202 is driven to install speakers of different sizes;

[0052] Thus, it is convenient for the operator to drive the sealing ring 604 to perform sealing treatment by extruding the housing assembly 1. At the same time, releasing the fixation of the disc 204 facilitates its quick installation. At the same time, the installation operation is simple and time-consuming.

[0053] The working principle and usage process of the present invention:

[0054] First, when the operator installs speakers of different specifications, the housing assembly 1 is snapped into the installation groove on the vehicle frame, and the position of the housing assembly 1 is positioned through the positioning block 103 and the installation groove. Then, the housing assembly 1 is snapped into the inner cavity of the door frame. The outer wall of the door frame abuts against the movable block 601, causing the driving moving plate 602 to squeeze the air cushion 603. At the same time, the deformation of the air cushion 603 drives the sealing ring 604 to move inward, making it closely fit with the vehicle frame. As the moving plate 602 moves, the positioning rod 605 is driven to move out of the inside of the disc 204, releasing the fixation of the disc 204.

[0055] Under the elastic force of the first spring 207, the mounting block 205 moves on the outer surface of the limiting ring 206 to limit the disc 204. At the same time, the disc 204 drives the connecting column 203 and one end of the arc-shaped member 202 to move inside the arc-shaped groove 201, making the arc-shaped member 202 present an arch shape, which presses against the inner wall of the vehicle frame installation groove for clamping low-frequency vibration speakers of different sizes. And as the mounting block 205 moves, it drives the pressing block 302 in the inner cavity to move, causing the pressing block 302 to drive the movable disc 301, and the pawl 307 will not block it. Since the movement of the mounting block 205 drives the clamping block 408 to gradually move into another inclined opening 409, it provides resistance for the first spring 207, preventing the arch amplitude of the arc-shaped member 202 from being too large. At the same time, the rotation of the disc 204 drives the inclined groove 208 to move to the outside of the inclined block 403. Then, due to the elastic force of the third spring 404, the inclined block 403 is driven to fit with the inner wall of the inclined groove 208. Then, the rotation of the disc 204 can also drive the inclined plate 501 to move, causing the support frame 502 installed inside the outer shell 101 to be extruded from the inside, and the rubber block at the end of the support frame 502 is closely fitted with the inner wall of the door frame to support the entire housing assembly 1. Thus, it is convenient for the operator to quickly install the housing assembly 1 through the clamping and support of the arc-shaped member 202 and the support frame 502. And through the design of the arch shape of the arc-shaped member 202, the sealing ring 604 and the rubber block at the end of the support frame 502, the vibration generated by the vehicle driving and the low frequency of the speaker is buffered, making it have a good buffering effect after installation and improving the service life of the equipment;

[0056] Subsequently, after the housing assembly 1 is installed, after a long time of use, due to the driving of the vehicle, the low-frequency vibration of the speaker, and the closing of the car door, the spring 207 undergoes elastic fatigue, which in turn causes the arch amplitude of the arc-shaped member 202 to decrease, making it impossible to fit closely with the inner wall of the frame installation groove, easily leading to unstable installation. Since the decrease in the arch amplitude of the arc-shaped member 202 due to elastic fatigue will drive the connecting column 203 to move in a reset manner, in this solution, the connecting column 203 drives the disc 204 and the mounting block 205 to rotate, causing the latch 408 on the mounting block 205 to move out of the inclined opening 409 and then move backward in a reset manner. At the same time, during the reset rotation of the mounting block 205, due to the design of the pawl 307 and the card slot 308, the movable disc 301 cannot move in a reset manner, and by squeezing the pressure block 302 through the mounting block 205, the pressure rod 303 will be driven to squeeze the connecting plate 306, and then the connecting plate 306 will drive the mounting plate 406 and the electromagnet 407 downward. As the electromagnet 407 moves, it will drive the electromagnet 407 to release the adsorption of the spherical ball 405, releasing the fixation of the spherical ball 405. Subsequently, when the car door is opened, the internal spherical ball 405 will move away from the inclined block 403 due to inertia. Then, when the door is closed, due to the excessive inertial force, the spherical ball 405 will be driven to impact the back of the inclined block 403. Through the extrusion force generated by the impact, the disc 204 will be driven to move, thereby driving the latch 408 on the mounting block 205 to move forward and snap into the inclined opening 409 of the front grid. Through the setting of the inclined opening 409, the latch 408 is snapped into the interior to maintain the limitation of the arc-shaped member 202. At the same time, the movement of the mounting block 205 will drive the latch 408 to move into the inner cavity and drive the movable disc 301 to move forward a little, strengthening the arch amplitude of the arc-shaped member 202, enabling it to re-engage with the inner wall of the installation groove. And through the reset of the latch 408, the electromagnet 407 is driven to move, enabling it to adsorb the spherical ball 405. Thus, when the spring 207 inside the housing assembly 1 undergoes elastic fatigue, the clamping effect of the arc-shaped member 202 is strengthened through the impact generated when closing the door, improving the stability.
