Preferably, but not limited to, in this embodiment, the height of the fixing structure 110 is at most equal to the adjustable step height of the connecting rod. In this embodiment, the height of the fixing structure 110 matches the height of the headrest speaker 100, so that the headrest speaker 100 can be engaged in the groove of the car seat headrest connecting rod, reducing the space occupied by the headrest speaker 100.

[0049] Preferably, in this embodiment, the front end face of the speaker body 120 has a plurality of speaker holes 121 evenly distributed.

[0050] In this embodiment, by setting the headrest speaker 100, an in-vehicle audio playback device can be added, improving the surround sound effect of in-vehicle audio playback. At the same time, the headrest speaker 100 has a relatively simple structure, is easy to assemble, and can be adapted to most types of vehicle seat structures.

[0051] More specifically, the fixing structure 110 includes a kit 111 and a fastener 112; the kit 111 is U-shaped and is fitted over the connecting rod; the fastener 112 is detachably connected to the open end of the kit 111 and forms a closed structure with the kit 111.

[0052] Preferably, in this embodiment, the back of the speaker body 120 is provided with a fixing structure 110 fixed to one end of the kit 111, so that the speaker body 120 and the kit 111 are kept in a fixed position.

[0053] Preferably, in this embodiment, the kit 111 is arranged horizontally, and the connecting rod should enter the kit 111 along the open end of the kit 111.

[0054] Preferably, in this embodiment, after the kit 111 is fitted and fixed to the speaker body 120, the speaker body 120 should be positioned towards the front of the car seat.

[0055] In this embodiment, the combination of fastener 112 and kit 111 enables the fixed structure 110 and connector to be detachably connected, while the speaker body 120 is bound to kit 111 to achieve the structural assembly of headrest speaker 100.

[0068] Preferably, the mobile device 300 is a mobile phone that is connected to the host 200 via Bluetooth.

[0069] In this embodiment, the mobile phone sends audio data to the host 200 via wireless transmission means such as Bluetooth. The host 200 sends audio data to the first speaker via wireless transmission means such as FM transmitter module / Bluetooth transmitter module or audio cable AUX, and the first speaker plays the audio. The host 200 can also send audio data to the second speaker 100 via wireless transmission means such as FM transmitter module / Bluetooth transmitter module or audio cable AUX, and the second speaker 100 plays the audio.

[0070] In this embodiment, if audio is played simultaneously through the headrest speaker 100 and the vehicle speaker, the in-vehicle audio surround effect can be improved, and either playback device can be selected according to the user's actual needs.

[0071] In summary, this embodiment proposes an audio playback system that enhances the in-vehicle surround sound effect by adding headrest speakers as players. At the same time, the headrest speakers have a relatively simple structure, can be quickly assembled, and are compatible with different vehicles, allowing for simple modifications to the vehicle interior.

[0072] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
