Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] Example 1: As Figures 1-6 ,include

[0030] The car speaker body 100 is circular, and the surface of the car speaker body 100 is a sound-bearing surface 120.

[0031] The mounting components include a spindle 200 and a rectangular clamping plate 210.

[0032] The card slot 300 has a rectangular insertion hole 320 on its inner wall. An L-shaped limiting card seat 330 is fixedly installed on the bottom inner wall of the card slot 300. The L-shaped limiting card seat 330 cooperates with the rectangular card plate 210 to lock.

[0033] The specific application scenario of this embodiment is as follows: The car speaker body 100 serves as the sound output component. Its circular design conforms to acoustic principles and helps to achieve uniform sound diffusion. The sound-emitting surface 120 can convert audio signals into sound and propagate them to the surrounding environment. The mounting component's insert shaft 200 and rectangular clamping plate 210 are key components for speaker installation. The insert shaft 200 plays a role in positioning and initial support, while the rectangular clamping plate 210 is used to lock into the clamping compartment 300. The clamping compartment 300 serves as the basic structure for installation. The rectangular insertion hole 320 on its inner wall provides a channel for the insertion of the rectangular clamping plate 210. The L-shaped limiting bracket 330 on the bottom inner wall can cooperate with the rectangular clamping plate 210. When the rectangular clamping plate 210 is inserted and rotated 90°, the L-shaped limiting bracket 330 can restrict the movement of the rectangular clamping plate 210, thereby firmly installing the car speaker body 100 on the clamping compartment 300, ensuring that the speaker will not loosen or shake during car operation, and guaranteeing the stability of sound playback.

[0034] Example 2: Figure 1 A signal cable connector 110 is fixedly installed on one side of the outer wall of the speaker body 100. The outer wall of the connector 110 extends to the outside of the speaker body 100. Rotation indicator arrows 130 are provided around the top outer wall of the speaker body 100.

[0035] The specific application scenario of this embodiment is as follows: The signal cable connector 110 is fixed to one side of the outer wall of the speaker body 100 and extends to the outside. Its function is to connect the audio signal cable and transmit the audio signal output by the car audio head unit to the inside of the speaker body 100, so that the speaker can convert the electrical signal into a sound signal for playback. The rotation indicator arrows 130 around the top outer wall of the speaker body 100 are for the convenience of the user to install the speaker correctly. During the installation process, after the rectangular card plate 210 is inserted into the rectangular socket 320, the user needs to rotate the speaker body 100 by 90° so that the rectangular card plate 210 is engaged with the L-shaped limiting card seat 330. The rotation indicator arrows 130 clearly indicate the direction of rotation, avoiding installation failure or insecure installation due to incorrect rotation direction, thus improving the accuracy and efficiency of installation.

[0036] Example 3: Figures 4-6The insert shaft 200 is fixedly installed in the middle of the bottom outer wall of the car speaker body 100. A rectangular clamping plate 210 is vertically fixedly installed on the bottom outer wall of the insert shaft 200. The width of the rectangular clamping plate 210 is greater than the diameter of the insert shaft 200. Circular through holes 211 are opened on the bottom inner walls of both ends of the rectangular clamping plate 210. Springs 220 are fixedly installed on the inner walls of the circular through holes 211. A limiting ball 230 is fixedly connected to the outer wall of the end of the spring 220 away from the car speaker body 100. The outer wall of the snap-fit ​​compartment 300 is fixedly installed with... The first vibration damping pad 310 is installed, and the rectangular insertion hole 320 extends through the first vibration damping pad 310 to the opening of the L-shaped limiting bracket 330. There are two L-shaped limiting brackets 330 symmetrically distributed on the left and right sides. The rectangular card plate 210 and the rectangular insertion hole 320 are connected by insertion. The two ends of the rectangular card plate 210 are rotated 90° to engage with the inner walls of the two L-shaped limiting brackets 330. The inner wall of the L-shaped limiting bracket 330 is provided with a spherical limiting groove, which engages with the outer wall of the limiting ball 230 for limiting.

[0037] The specific application scenario of this embodiment is as follows: A spring 220 and a limiting ball 230 are installed in the circular through holes 211 on the bottom inner walls of both ends of the rectangular card plate 210. When the rectangular card plate 210 is inserted into the rectangular insertion hole 320 and rotated 90° to engage with the inner wall of the L-shaped limiting card seat 330, the spring 220 will be compressed and the limiting ball 230 will be squeezed. When rotated to the 90° position, the limiting ball 230 will be engaged in the spherical limiting groove on the inner wall of the L-shaped limiting card seat 330 under the elastic force of the spring 220, thereby achieving further locking. This locking method not only enhances the stability of the installation, but also prevents the rectangular card plate 210 from coming out of the L-shaped limiting card seat 330 due to vibration during vehicle operation. The first vibration damping pad 310 on the outer wall of the engaging compartment 300 can reduce the transmission of vibration generated by the speaker during operation to the surrounding structure, reduce noise and resonance caused by vibration, and improve the sound quality.

[0038] Example 4: Figure 4 The bottom outer wall of the snap-fit ​​compartment 300 is provided with a support plate 430. The top of the support plate 430 is provided with a protrusion, which is connected to the bottom inner wall of the snap-fit ​​compartment 300 by insertion. The top four outer walls of the support plate 430 are fixedly installed with a second vibration damping pad 431. The bottom of the support plate 430 is provided with a mounting plate 400. The top of the mounting plate 400 is fixedly installed with a third vibration damping pad 410. The mounting plate 400, the third vibration damping pad 410, the support plate 430 and the inner wall of the snap-fit ​​compartment 300 are fixedly connected by a first bolt 420. The mounting plate 400 is fixedly connected to the car mounting plate by a second bolt.

[0039] The specific application scenario of this embodiment is as follows: The support plate 430 on the bottom outer wall of the snap-fit ​​compartment 300 is connected to the bottom inner wall of the snap-fit ​​compartment 300 through the top protrusion, providing additional support for the snap-fit ​​compartment 300. The second damping pad 431 on the top four outer walls of the support plate 430 and the third damping pad 410 on the top of the mounting plate 400 work together to dampen vibration. When the speaker is working, it will generate a certain amount of vibration. These vibrations are transmitted to the support plate 430 and the mounting plate 400 through the snap-fit ​​compartment 300. The damping pads can absorb and buffer these vibrations, reducing the vibration transmitted to the car mounting plate, thereby reducing the noise caused by vibration and the impact on the car structure. The mounting plate 400, the third damping pad 410, the support plate 430 and the inner wall of the snap-fit ​​compartment 300 are fixedly connected by the first bolt 420. This connection method ensures the stability of the entire installation structure. At the same time, the mounting plate 400 is fixedly connected to the car mounting plate by the second bolt, firmly installing the entire speaker system on the car and ensuring the normal operation of the speaker during the car's driving process.

[0040] The working principle of this utility model is as follows: When used by those skilled in the art, during the installation process, the insert shaft 200 guides the speaker body 100 to be initially positioned, the rectangular card plate 210 is inserted into the rectangular insertion hole 320 of the card receiving compartment 300, and rotated 90° as indicated by the rotation indicator arrow 130, and locked in place with the L-shaped limiting card seat 330. During installation, the signal cable connector 110 connects to the car audio head unit to transmit audio signals. To ensure stable installation and optimized sound quality, the limiting ball 230 of the rectangular card plate 210, under the action of the spring 220, is engaged in the spherical limiting groove of the L-shaped limiting card seat 330 to further prevent loosening. The first damping pad 310 on the outer wall of the card slot 300, the second damping pad 431 on the top of the support plate 430, and the third damping pad 410 on the top of the mounting plate 400 can absorb and buffer the vibration generated when the speaker is working, reducing noise and resonance. The support plate 430 provides additional support for the card slot 300. The mounting plate 400 is connected by two levels of bolts to securely install the entire speaker system on the car, ensuring that the speaker works stably during vehicle operation and outputs high-quality sound.
