[0026] See also Figures 1 to 7 The present embodiment provides a vehicle-mounted subwoofer audio device, including a housing 1, which includes an upper housing 101 and a lower housing 102. The upper housing 101 and the lower housing 102 enclose a cavity 103 and a sound guide tube 104. The sound guide tube 104 is arranged at one side edge of the cavity 103. The sound guide tube 104 is curved, and the inner end of the sound guide tube 104 is connected to the cavity 103. The outer end of the sound guide tube 104 is provided with an opening 105. A speaker 2 is provided on the upper housing 101. When the speaker 2 vibrates, the gas in the cavity 103 is connected to the external atmosphere through the sound guide tube 104. Function: The shell includes an upper shell and a lower shell, and the upper shell and the lower shell enclose a cavity and a sound guide tube. The sound guide tube is arranged at one side edge of the cavity, and the sound guide tube is curved (i.e., forming a spiral shell shape). The inner end of the sound guide tube is connected with the cavity, and the outer end of the sound guide tube is provided with an opening. A speaker is provided on the upper shell; therefore, when the speaker vibrates, the gas in the cavity is connected with the external atmosphere through the sound guide tube (similar to the sound conduction principle of the spiral shell), and the acoustic characteristics are excellent, the bass dives deep enough, the sound quality is full and deep, and the expected effect is achieved very well. Therefore, after being made into an open shell, the cavity volume of the subwoofer is greatly reduced, thereby greatly reducing the volume of the subwoofer.

[0027] Specifically, the internal width of the sound guide tube 104 gradually increases from the inner end to the outer end, forming a spiral shell-like gradient. Purpose: The subwoofer's use of this spiral shell-like gradient opening structure further enriches the sound layering, making the sound more three-dimensional and full-bodied, creating an immersive experience. Because the spiral shell-like gradient opening structure of the long sound guide tube is smaller inside and larger outside, forming an overall spiral shell shape, it facilitates the flow of air inside and outside the cavity when the speaker vibrates.

[0028] Specifically, the inner width of the sound guide tube 104 is 48.5536 mm ± 5 mm, and the outer width of the sound guide tube 104 is 54.1732 mm ± 5 mm. Purpose: Such a width distribution better meets the requirements of heavy bass speakers.

[0029] Specifically, the path length of the sound guide tube 104 is 426.649 mm ± 5 mm. Function: Such a length distribution is more in line with the requirements of heavy bass sound.

[0030] Specifically, the sound guide tube 104 is protruding from the front outer wall of the cavity 103. Function: The protruding configuration facilitates the sound guide tube and the cavity to function separately.

[0031] Specifically, the inner end of the sound guide tube 104 is connected to the left front end of the cavity 103, and the outer end of the sound guide tube 104 extends rightward to the right front of the cavity 103. Function: This arrangement can achieve the connection between the sound guide tube 104 and the outer wall of the cavity.

[0032] Specifically, the outer wall of the sound guide tube 104 and the outer wall of the cavity 103 are connected by a plurality of connecting arms 106, which are sequentially distributed along the extension direction of the sound guide tube 104. Function: The setting of the connecting arms can achieve support for the sound guide tube.

[0033] Specifically, the edges of the upper shell 101 and the lower shell 102 are detachably and hermetically connected. Function: The detachability facilitates processing, while the hermetically connected connection ensures accurate air flow and better bass effect.

[0034] Specifically, the housing 1 is triangular in shape with a gradually increasing volume from the back to the front, and the axial direction of the speaker 2 is perpendicular to the upper housing 101. This facilitates the flow of gas in the sound guide tube 104 when the speaker 2 vibrates.

[0035] Specifically, speaker 2 is a 6.5-inch ± 0.5-inch speaker, and the sum of the volumes of the cavity 103 and the sound guide tube 104 is 9.22L ± 1L. Function: In conventional subwoofer solutions, in order to meet the vibration requirements of the speaker, a 6.5-inch speaker generally requires a cavity with a volume exceeding 17L. If the cavity capacity is insufficient, the low-frequency resonance frequency of the speaker will increase, the speaker will not dive deep enough, the bass effect will be greatly reduced, and the user experience will be reduced. However, the vehicle-mounted subwoofer speaker of this embodiment uses an open shell design. When the speaker vibrates, the gas in the cavity is connected to the external atmosphere through the sound guide tube, thereby greatly reducing the cavity volume of the subwoofer. In this example, the actual cavity volume of the subwoofer + the volume of the sound guide tube 104 is 9.22L. That is, the cavity volume of the 6.5-inch speaker (loudspeaker) in this example is 17L. After being made into an open shell, the total cavity volume is 9.2L, which is a volume reduction of about 45%, greatly reducing the volume of the subwoofer speaker.

[0036] Technical effect:

[0037] 1. After reducing the volume of parts, the available space of the car is increased, and the weight of the whole vehicle can also be reduced, which is in line with the development trend of the modern automotive parts industry, integration, miniaturization and lightweight.

[0038] 2. As the size and weight of parts decrease, the cost will also decrease, which will help to be more competitive in the increasingly competitive automotive industry.

[0039] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
