[0056] Specifically, the connecting strip 204 is provided with six, and three connecting strips 204 are arranged on each side frame 201. At least three clamping holes 1011 are arranged on each side plate 101. The backrest spring 2 is fixed to the backrest framework assembly 1 by the six connecting strips 204, which is more firm and stable, and ensures the stability of the connection between the backrest framework assembly 1 and the backrest spring 2.

[0057] It can be understood that in other embodiments, the backrest spring 2 and the backrest framework assembly 1 can also be connected together by screws or bolts, and are not limited thereto.

[0058] In this embodiment, the number of vibrator assemblies 3 is two, and the two vibrator assemblies 3 are oppositely arranged on the backrest spring 2.

[0064] In the embodiment, two identical vibrator assemblies 3 are arranged in parallel on the backrest spring 2 and are directly clamped and fixed on the backrest spring 2 through the clamping part 302; after the vibrator assembly 3 is mounted on the backrest spring 2, a backrest spring assembly is formed, the hook part 2041 on the backrest spring assembly is directly hung on the clamping hole 1011 of the side plate 101 of the backrest framework assembly 1, and then a first assembly is formed; after the first assembly is assembled, the foam is directly sleeved on the first assembly, and then the skin is coated, so that the whole seat back structure is assembled; after the assembly is completed, the excitation surface of the vibrator assembly 3 is in surface contact with the surface of the foam facing the excitation surface; the vibrator assembly 3 is provided with a wire harness, which can be connected to the input wire harness interface of the power amplifier on the vehicle, so as to realize communication; after the communication, the vibrator assembly 3 generates excitation vibration, which is transmitted to the human body through the foam and the skin, so that the human body forms an immersive music rhythm vibration atmosphere through hearing and touch.

[0065] In the related art, the massage unit is embedded in the foaming structure, and the massage unit performs a vibration action through micro-processed signal input driving, and the multi-point vibration is similar to a knocking type massage. Although the arrangement structure has the functions of rhythm and massage, the two functions can only be executed when music is played, and single selection cannot be performed. Meanwhile, the knocking type massage has the disadvantages of insufficient ejection feeling and poor massage comfort compared with the traditional air bag massage. Moreover, the massage unit directly contacts the human body through the skin, the excitation feeling is too direct, and the rhythm experience is poor. Meanwhile, a plurality of massage units are added with a microprocessor, and the cost is high.

[0066] In the embodiment, the seat back also comprises an air bag massage structure, which can adopt the structure in the prior art and will not be described in detail here. While realizing the function of the air bag massage, the seat back is provided with two low-frequency vibrators, and the vibrator assembly 3 can directly realize the music rhythm function through the input of the power amplifier of the vehicle. The vibrator assembly 3 is arranged on the backrest spring 2, vibration feeling is transmitted to the human body through the excitation of the foam and the skin, and no microprocessor is involved. The advantages of the embodiment include strong music rhythm experience, simple arrangement structure, low cost and the like.
