Description

Technical Field

[0001] The utility model relates to the technical field of seat headrest speaker structures, and particularly relates to a wiring harness structure for a seat headrest speaker. Background Art

[0002] A seat headrest speaker is a sound device built into an automobile seat headrest, designed to provide a personalized audio experience for drivers and passengers. This speaker is exquisitely designed and integrated with the headrest, saving space and reducing in-vehicle sound interference. Users can connect their mobile phones or other audio devices via Bluetooth or the in-vehicle system to enjoy music, podcasts, or phone calls. The sound quality of seat headrest speakers is usually better than that of the vehicle's standard speakers, providing a clearer and more stereo sound effect. Some high-end products also have a noise control function that can automatically adjust the volume according to the in-vehicle noise to ensure clear sound quality. In addition, they usually have a simple and easy-to-use control panel or remote control function, facilitating safe operation by the driver during driving. Seat headrest speakers enhance the in-vehicle audio experience, making driving and riding more enjoyable. However, during driving, passengers or drivers are prone to pulling and displacing the speaker wiring harness during adjustment or touching, resulting in disconnection of the wiring, or even damage. Moreover, the harsh environment such as vibrations generated during vehicle driving will also affect the stability of the contact. Therefore, this application provides a wiring harness structure for a seat headrest speaker. Summary of the Invention
