Motorcycle audio device and motorcycle having the same Related applications

[0001] This application claims priority to Chinese patent application number CN 2024200081370 filed on January 3, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to an audio device adapted for a motorcycle and a motorcycle having the audio device, and in particular to an audio device suitable for being mounted on a front fender of a motorcycle. Background Art

[0003] Cars are commonly equipped with in-car audio systems to facilitate in-car communication, entertainment, and other functions. Currently, some audio devices are also designed for motorcycles. For example, the solution disclosed in patent CN216994684U installs the speakers on the motorcycle's trunk lid. While this solution provides good protection for the speakers, for example, by reducing the impact of rain, it significantly limits installation space. Patent CN206475987U discloses a solution where left and right speakers are installed on the left and right sides of the motorcycle bumper, respectively. Subwoofers, which require large cavities, are not suitable for these left and right speakers, as they would be too large and significantly degrade the vehicle's appearance. Furthermore, existing solutions, such as those disclosed in patents CN216232755U and CN200981601Y, mostly use screws, Velcro, or other methods to mount speakers on motorcycles. However, due to the poor road conditions of motorcycles, the speakers can become loose or even detach from the vehicle after a period of use on bumpy roads, such as in the wild, making the installation insecure.

The cabinet 1 has a panel 11 facing the rear, and the bass sound module 2 is mounted on the panel 11. The cabinet 1 also has a top plate 12 and a bottom plate 13. The top plate 12 is fixed to a part of the front guard of the motorcycle, and the bottom plate 13 is fixed to another part of the front guard of the motorcycle. The length direction of the cabinet 1 is consistent with the front and rear direction of the motorcycle, so that the second cavity 10 is a long and narrow cavity extending in the front and rear direction. Furthermore, the length of the cabinet 1 (the dimension in the front and rear direction) is more than twice its dimension in the up and down direction (height) or the left and right direction (width).

[0045] The bass sound module 2 includes a basin frame 21, a vibration system, and a drive system. The basin frame 21, the vibration system, and the drive system 23 form a first cavity 20. A second cavity 10 is provided within the enclosure 1 for the bass sound module 2, forming the sound chamber of the bass sound module 2. The basin frame 21 is connected to the enclosure 1 and is provided with an airflow channel 210 for connecting the first cavity 20 and the second cavity 10. Specifically, there can be multiple airflow channels 210, which can be hollow portions such as windows provided on the basin frame 21. The vibration system includes a cone 22 and a voice coil, and may also include a dust cap, positioning brackets, etc. The cone 22 has a truncated conical cone portion. The outer edge of the cone 22 is fixed to the basin frame 21 and has a front side facing the outside world and a back side facing the inside (e.g., the drive system 23). The bass sound module 2 is configured to be located in front of the seat of the motorcycle, and the sound radiation surface of the vibration system (ie, the front of the sound cone 22) is configured to face the rear of the motorcycle.

[0046] The driving system 23 is provided with a through hole 230 extending in the front-to-back direction, and the through hole 230 connects the first cavity 20 and the second cavity 10. Furthermore, the driving system 23 includes a T-iron 231 and a magnet and a front plate that cooperate with the T-iron 231 to form a magnetic gap. A portion of the voice coil (the portion wound with the coil) can be inserted into the magnetic gap to vibrate back and forth. The magnet and the front plate are fixed on the T-iron 231, and the front plate is fixed on the basin frame 21. The above-mentioned through hole 230 is opened in the middle of the T-iron 231 and passes through the T-iron 231 in the front-to-back direction. The front end of the through hole 230 is connected to the first cavity 20, and the rear end of the through hole 230 is connected to the second cavity 10. In other words, the first cavity 20 and the second cavity 10 are connected through multiple air flow channels 210 and a single through hole 230, forming a gas circulation circuit. In addition, the through hole 230 is covered with a breathable material layer 24.

[0047] As shown in Figures 1, 2, and 7, the housing 1 is provided with multiple connecting assemblies 3 for connecting to the motorcycle's front fender. Each connecting assembly 3 includes a connecting post 31 and a resilient rubber sleeve 32 that fits over the connecting post 31.

Specifically, multiple first connecting assemblies 3a are provided on the top plate 12, and multiple second connecting assemblies 3b are provided on the bottom plate 13. Correspondingly, mounting holes are provided on the front fender. Inserting the connecting assemblies 3 into the corresponding mounting holes allows the housing 1 and the front fender to be assembled. Furthermore, the rubber sleeve 32 is provided with an annular groove. Once assembled, the wall of the hole in the front fender snaps into the groove, facilitating further positioning and ensuring secure installation. The rubber sleeve 32 has a certain wall thickness, which can buffer the collision between the box body 1 and the front guard plate under bumpy road conditions and ensure effective connection.

[0048] The midrange or tweeter unit 200 is positioned above, to the left, or to the right of the woofer module 2, with its sound radiation surface facing rearward. The midrange or tweeter unit 200 includes a bracket 51, a diaphragm 52 connected to the bracket 51, and a mask 53, which covers the rear side of the diaphragm 52.

[0049] A first mounting hole 111 and a second mounting hole 112 are provided on the panel 11. The woofer sound module 2 is installed in the first mounting hole 111, and the midrange or tweeter unit 200 is installed in the second mounting hole 112. In this embodiment, the panel 11 is a part of the cabinet 1. In other embodiments, the panel 11 is fixedly provided on the cabinet 1, and the panel 11 is not a component of the cabinet 1. The first mounting hole 111 is connected to the second cavity 10, and the midrange or tweeter unit 200 is located outside the cabinet 1, specifically above the cabinet 1. The basin frame 21 of the woofer sound module is inserted into the first mounting hole 111, and the bracket 51 of the midrange or tweeter unit 200 is inserted into the second mounting hole 112.

[0050] It should also be noted that, with the exception of the rear end secured to the panel 11, the rest of the frame 21 of the bass module 2 is free from contact with the inner wall of the cabinet 1, maintaining a constant gap to allow airflow. Furthermore, the gap between the frame 21 and the inner wall of the cabinet 1 gradually widens from back to front, thus preventing interference or weakening of the airflow. This reduces distortion, reduces noise, and improves sensitivity.

[0051] Two groups of connection terminals 4 are also provided on the panel 11, one group of which is connected to the positive and negative leads of the voice coil of the bass sound module 2, and the other group of which is connected to the positive and negative leads of the voice coil of the midrange or tweeter unit 200.
