Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted integrated speaker technology, and in particular to a subwoofer enclosure structure for a vehicle-mounted integrated speaker. Background Technology

[0002] The subwoofer enclosure structure of a vehicle-mounted integrated speaker mainly includes a head unit, a head unit cover, a pair of symmetrically placed speakers, a main sound chamber, and a subwoofer chamber. The main sound chamber and the subwoofer chamber are interconnected, a well-designed feature that effectively enhances bass performance while saving production costs and increasing production efficiency, thus possessing significant economic value.

[0003] For example, the existing publication number CN206775663U discloses a subwoofer enclosure structure for an integrated vehicle speaker, which specifically includes an audio host, a host cover that cooperates with the audio host, a pair of speakers symmetrically placed on both sides of the audio host, a first sound cavity and a second sound cavity that is a subwoofer cavity, and the subwoofer cavity is connected to the main sound cavity. The present invention provides a subwoofer enclosure structure for an integrated vehicle speaker with a reasonable structural design and good bass effect, which effectively saves production costs, improves production efficiency, and has great economic value.

[0004] Existing integrated car speaker subwoofer enclosures leave the speaker open to the outside environment when not in use. Dust and other impurities can easily enter the speaker and accumulate on the diaphragm. Dust on the diaphragm can cause the sound to be too low and muddy, affecting the damping balance of the subwoofer unit and consequently impacting overall sound quality. Furthermore, dust covering electronic components can hinder heat dissipation, accelerate component aging, and shorten their lifespan. Therefore, we propose a new subwoofer enclosure structure for integrated car speakers. Utility Model Content

Connecting shafts 7 are fixedly mounted at the center positions of both sides of each movable plate 6, and the connecting shafts 7 can be rotatably mounted inside the groove 4. Each movable piece 6 can rotate to be aligned on the same line, at which point multiple movable pieces 6 can seal the groove 4. A protective cover 8 is fixedly installed on the outside of the housing 2. One end of each of multiple connecting shafts 7 extends into the protective cover 8, and a first bevel gear 9 is fixedly installed at the end of each connecting shaft 7. A drive shaft 10 is rotatably installed inside the protective cover 8, and multiple equidistantly distributed second bevel gears 11 are fixedly installed on the drive shaft 10. The second bevel gears 11 mesh with the first bevel gears 9 respectively. A motor 12 is fixedly installed on the outside of the protective cover 8, and the output shaft of the motor 12 is fixedly connected to the drive shaft 10. The corners of the housing 2 are rounded.

When the speaker 5 is working, refer to Figure 4 As shown, multiple movable pieces 6 are in a parallel state, and the groove 4 is in a state of communication with the outside world, allowing the sound from the speaker 5 to propagate to the outside. When the speaker 5 is not working, the motor 12 drives the drive shaft 10 to rotate, the second bevel gear 11 on the drive shaft 10 rotates and drives the first bevel gear 9 to rotate, and the movable pieces 6 rotate around the connecting shaft 7, so that the multiple movable pieces 6 rotate to a collinear state. The multiple movable pieces 6 cooperate and can seal the groove 4, preventing external dust or impurities from entering the groove 4.

[0022] Among them, such as Figure 3 and Figure 4As shown, an adjustment mechanism is provided on the mounting base 1. The adjustment mechanism is connected to the support shaft 3 and is used to adjust the orientation of the housing 2. The adjustment mechanism includes a friction wheel 13, which is fixedly connected to the support shaft 3. A support block 14 is fixedly installed on the mounting base 1.
