Description

Technical Field

[0001] This utility model relates to the field of vehicle audio technology, specifically to a vehicle speaker. Background Technology

[0002] Car audio refers to the audio system installed in a vehicle. The most basic requirement for a system to be called an audio system is the ability to reproduce sound. Its anti-interference technology uses chokes connected in series between the power supply and the speakers to filter interference from external noise. The speaker, also known as a loudspeaker, is an indispensable component of a car audio system. All music is emitted through the speaker for people to listen to and enjoy. As the only device that converts electrical energy into "sound energy," the quality and characteristics of the speaker play a decisive role in the sound quality of the entire audio system.

[0003] Currently, most car audio equipment on the market uses dust filters to prevent dust from entering the speaker. However, most dust filters are connected by screws or are directly embedded in the speaker housing. As a result, after a long period of use, it is very troublesome to replace the dust filter when the dust accumulates heavily. The speaker needs to be disassembled to replace the dust filter, and disassembly can easily damage internal parts. Therefore, it is very important to design a car audio device that allows for easy replacement of the dust filter. Summary of the Invention

This enables the bracket to be removed along with the dustproof net at any time. During normal use, a gear rack secures the bracket within the frame. When replacement is needed, the gear rack can be loosened to easily remove the dustproof net for cleaning or direct replacement. Furthermore, removing the dustproof net allows for direct maintenance of the speaker's internal components, effectively improving the efficiency and ease of dustproof net replacement and thus enhancing the convenience of speaker maintenance.

[0005] To achieve the above objectives, a vehicle-mounted speaker is provided, comprising a protective shell, a controller fixedly connected to the inner surface of the protective shell, multiple connection ports fixedly connected to the front surface of the controller, a frame fixedly connected to the upper surface of the protective shell, two slide rails fixedly connected to the inner surface of the frame, a dustproof device slidably connected to the inner surface of the slide rails, a sound insulation plate fixedly connected to the inner surface of the protective shell, and a sound generator fixedly connected to the upper surface of the controller.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figures 1 to 4 This utility model discloses a car speaker, comprising a protective shell 1, a controller 2 fixedly connected to the inner surface of the protective shell 1, and multiple connection ports 3 fixedly connected to the front surface of the controller 2. A frame 4 is fixedly connected to the upper surface of the protective shell 1, and two slide rails 5 are fixedly connected to the inner surface of the frame 4. A dustproof device 6 is slidably connected to the inner surface of the slide rails 5. A sound insulation plate 8 is fixedly connected to the inner surface of the protective shell 1. A speaker 9 is fixedly connected to the upper surface of the controller 2. The controller 2 contains an intelligent audio processing module for intelligently adjusting audio signals and improving sound quality. This module automatically adjusts the audio effect according to the in-car environment, and can adjust volume, tone, and sound effects to provide a more personalized audio experience.

[0023] The dustproof device 6 includes a bracket 601, a limiting plate 602, a dustproof net 603, a sliding rod 604, a rotating groove 605, a rotating rod 606, a spur gear 607, a gear rack 608, a sliding plate 609, a connecting rod 610, and a rotating handle 611. The bracket 601 is slidably connected to the inner surface of the slide rail 5. The limiting plate 602 is fixedly connected to the inner surface of the bracket 601 near its center. The dustproof net 603 is movably connected to the upper surface of the limiting plate 602. The sliding rod 604 is fixedly connected to the rear surface of the bracket 601. The rotating groove 605 is fixedly connected to the inner surface of the sliding rod 604. The rotating rod 606 is rotatably connected to the inner annular surface of the rotating groove 605. The spur gear 607 is fixedly connected to the annular surface of the rotating rod 606. The gear rack 608 is meshed with the annular surface of the spur gear 607. The sliding plate 609 is fixedly connected to the inner surface of the sliding rod 604. The connecting rod 610 is fixedly connected to the rear surface of the spur gear 607, and the rotating handle 611 is fixedly connected to the other end of the connecting rod 610. An opening is provided at the connection between the slide rod 604 and the bracket so that the slide rod 604 can pass through it.

[0024] A power cord 7 is fixedly connected to the rear surface of the controller 2, and a pull rod 10 is fixedly connected to the front surface of the bracket 601.

[0025] Working principle: When using, first place the speaker in the desired location inside the car, then connect the power cord 7 to the power supply, and then connect it to the corresponding connector according to the required connection method. After a period of use, dust will accumulate on the dustproof device 6. If replacement is needed, use the rotating handle 611 to rotate the connecting rod 610. The rotation of the connecting rod 610 drives the spur gear 607 to rotate, which retracts the protruding gear rack 608 into the slide rod 604. Then, pull the bracket 601 outwards via the pull rod 10. The bracket 601 will then be removed along the slide rail 5. After removing the dustproof net 603, gently push it from bottom to top to remove it from the limiting plate 602. After removing it, clean the dustproof net 603 and put it back into the bracket 601. After putting it back in, push the bracket 601 back into the frame 4 along the slide rail 5. The slide rod 604 will enter the circular hole on the frame 4. After the bracket 601 enters the deepest part, rotate the connecting rod 601 by rotating the handle 611, which will drive the spur gear 607 to rotate. The rotation of the spur gear 607 will drive the gear rack 608 to move outward, and finally lock it on the outer surface of the frame 4 to prevent the bracket 601 from falling off.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
