It cannot be understood as a limitation of the present application.

[0040] The technical solutions of the present application will be further described below in combination with the specific embodiments. Figures 1-6 The technical solutions of the present application will be further described below in combination with the specific embodiments.

[0041] Please refer to Figure 1 The present application provides an intelligent headrest sound system (which can be a vehicle-mounted intelligent headrest sound system), which comprises a headrest body 1 (such as a waist rest, a headrest, an armrest, a leg rest, etc.) and a sound system (not marked in the figure). The headrest body 1 is used to provide flexible support for the head and neck of the user, and mainly comprises a flexible support layer and a surface layer wrapped outside the flexible support layer; optionally, the flexible support layer can be a sponge layer, and the surface layer can be a soft cloth layer. The specific material of the headrest body 1 is not limited, and the scheme should be included in the interpretation range of the headrest body 1 regardless of the specific material of the headrest body 1.

[0042] On this basis, the headrest body 1 has a contact surface in contact with the user. Correspondingly, the contact surface is divided into a vibration area 11, at this time, the sound system is arranged on the headrest body 1, and the sound system comprises a vibration speaker 21 and a moving coil speaker 28.

[0043] It can be understood that the vibration speaker 21 is composed of an electromagnetic coil and a vibration module, the vibration speaker 21 has sound emitting and vibration functions, and the moving coil speaker 28 is composed of a magnet, a yoke, a diaphragm and a voice coil, and mainly has a sound emitting function, and the sound emitting frequency of the vibration speaker 21 is higher than that of the moving coil speaker 28, so that the vibration speaker 21 can emit sound and vibration, achieve a massage effect, and the moving coil speaker 28 is used to play audio, supplement the sound field, and provide excellent sound quality experience.

[0044] The vibration speaker 21 is located on the vibration area 11. Generally, the vibration speaker 21 realizes vibration sound emission through magnetic vibration principle, and based on the above structure, when the vibration speaker 21 emits sound, the vibration force generated by the vibration speaker 21 can be transmitted to the surface layer of the body of the headrest 1, and then drive the vibration area 11 to vibrate. Since the vibration area 11 is located on the contact surface, the vibration area 11 can contact the user, so that the user can be vibrated and massaged during vibration.

[0045] It can be understood that in the process of arranging the vibration speaker 21 on the vibration area 11, there are various installation methods. In one embodiment, the vibration speaker 21 can be directly adhered and fixed to the inner wall of the surface layer; in another embodiment, the vibration speaker 21 can also be installed on the inner wall of the surface layer by sewing, so as to realize the mutual connection between the vibration area 11 and the vibration speaker 21, and then the vibration force can be stably transmitted to the head and neck. The specific arrangement of the vibration speaker 21 is not limited here.

[0046] The moving coil speaker 28 is located at the remaining position of the body of the headrest 1 except the contact surface, and the specific installation method of the moving coil speaker 28 is not described here. In this way, when the moving coil speaker 28 emits sound, the sound transmission channel can be avoided to be blocked, and better sound emitting feeling can be obtained.

[0047] In the above embodiment, on the one hand, by arranging the vibration speaker 21 on the body of the headrest 1, the user can be massaged by using the magnetic vibration principle, blood circulation is promoted, and the fatigue of the user is relieved. On the other hand, by arranging the moving coil speaker 28 on the body of the headrest 1, the effect of playing audio is achieved, and in the vehicle condition, the acoustic effect in the vehicle can be improved, and the sound system of the vehicle is supplemented. The use experience of the headrest or even the vehicle headrest is significantly optimized.

[0048] Further, with reference to Figure 2To optimize the experience effect of the backrest body 1, the backrest body 1 in the embodiment includes a backrest part 12 and a side pillow part 13. The side pillow part 13 extends in a strip shape, and one end of the side pillow part 13 is connected to the backrest part 12. Specifically, the number of the side pillow part 13 is two, and the two side pillow parts 13 are arranged on opposite sides of the backrest part 12. At this time, the backrest part 12 and the two side pillow parts 13 form a U-shaped backrest structure, and a supporting recess is formed between the backrest part 12 and the side pillow part 13.

[0049] In some embodiments, the backrest body 1 can be hung on the neck of the user through the supporting recess when in use. At this time, the backrest part 12 can provide support for the head, the back of the waist, and other parts of the human body, and the side pillow part 13 can firmly hold the backrest body 1 on the neck side, the waist side, and other parts of the human body, and at the same time provide stable support for the neck. At this time, the backrest body 1 can be closely attached to the user and is not easy to fall off. It can be understood that the surface area of the backrest body 1 towards the supporting recess constitutes a contact surface. It can also be understood that the contact surface is located at the inner edge of the supporting recess.

[0050] Optionally, the vibration horn 21 has multiple distribution modes. In one embodiment, the vibration area 11 can be divided and arranged at the contact surface of the backrest part 12, so as to massage the cervical vertebrae, lumbar vertebrae, and other parts of the user. In another embodiment, the vibration area 11 can also be divided and arranged at the contact surface of the side pillow part 13, so as to massage the trapezius muscle on the side of the neck of the user or the waist muscle. Alternatively, multiple groups of vibration horns 21 can be arranged in the backrest part 12 and the side pillow part 13, so as to provide all-around massage for the action part.

[0051] Here, the specific arrangement position of the vibration area 11 can be adjusted according to the actual needs of the product, which is not limited here. As long as the vibration massage effect can be achieved, the position of the vibration horn 21 should be included in the interpretation range of the vibration area 11, regardless of where the vibration horn 21 is arranged.

[0052] In the embodiment, the vibration horn 21 is located at the bending connection between the backrest part 12 and the side pillow part 13, so as to achieve accurate and comprehensive massage effect.

[0053] In addition, in order to reduce the blocking sound, the moving coil horn 28 in the embodiment is arranged at one end of the side pillow part 13 away from the backrest part 12, so as to realize sound externalization. At this time, the moving coil horn 28 can face the front of the user and externalize in the wide space, which is beneficial to fully disperse the sound to the surrounding or the vehicle, and the sound effect is better.

[0054] Further, with reference to Figure 3In order to control the sound of the vibration speaker 21 and the moving coil speaker 28, the sound system further comprises a master control chip 22, which is electrically connected with the vibration speaker 21 and the moving coil speaker 28, and is used for controlling the sound of the vibration speaker 21 and the moving coil speaker 28. It can be understood that the master control chip 22 usually comprises a digital-to-analog converter and an amplifier and the like, which is used for converting a digital signal into an analog signal for the vibration speaker 21 and the moving coil speaker 28 to sound, and has the functions of processing an audio signal and controlling an audio output, and the specific principle of the master control chip 22 will not be described here.

[0055] It needs to be explained that the master control chip 22 needs to be connected to a power supply to work. Based on this, the master control chip 22 is arranged on a circuit board, and the vibration speaker 21 is electrically connected with the circuit on the circuit board; at the same time, the embodiment further comprises a power module 3, and a power-on interface 4 is arranged on the outer side of the body 1 of the headrest, and the power module 3 is connected with the power-on interface 4 and the sound system respectively; specifically, the power module 3 can be a battery module, and the battery module can be connected with the power-on interface 4 and the circuit board of the sound system through a cable respectively, the power-on interface 4 is used for connecting with an external power supply, and the power module 3 can supply power to the master control chip 22, the vibration speaker 21 and the moving coil speaker 28 and the like through the circuit board, so as to ensure that each component in the sound system can operate normally.

[0056] On this basis, in order to control the sound action, it is also necessary to input the sound source, and optionally, the sound system can be selectively inputted with a sound source in a wireless connection mode or a wired connection mode.

[0057] Among them, in one of the embodiments provided in the present application, the sound system is controlled to start and stop in a wireless connection mode, and the sound system further comprises a Bluetooth module 23. Specifically, the Bluetooth module 23 is installed on the circuit board and is powered through the circuit board, and the Bluetooth module 23 is electrically connected with the master control chip 22, and the Bluetooth module 23 is used for wireless connection with a mobile terminal device or a vehicle-mounted system; it can be understood that the common Bluetooth module 23 supports A2DP protocol, and can realize wireless connection with a mobile terminal device or a vehicle-mounted system under 2.4GHz frequency band, at this time, the mobile terminal device includes but is not limited to a smart phone, a tablet computer, a portable computer and the like, and the vehicle-mounted system can be an Android system.

[0058] Based on the above setting, the sound system is controlled to sound and vibrate by interacting with the mobile terminal device or the vehicle-mounted system, and wireless sound source input is realized, and the use convenience of the headrest sound system is optimized and improved.

[0059] Further, the Bluetooth module 23 can be configured as a TWS Bluetooth module 23. It can be understood that the TWS Bluetooth module 23 refers to a Bluetooth module 23 supporting TWS function, and it can be understood that TWS (True Wireless Stereo) refers to a truly wireless stereo technology, allowing multiple audio devices to be connected through wireless signals, realizing stereo effect, and common TWS Bluetooth module 23 models include TICC256x series, CSR8670, etc. The specific model of the TWS Bluetooth module 23 can be selected according to actual needs, which is not limited here, and the implementation principle is not described here.

[0060] At the same time, the vehicle is usually equipped with a car audio, and the car audio is in communication connection with the vehicle system or the mobile terminal device. The car audio on the vehicle and the mobile terminal device are usually also equipped with a TWS Bluetooth module 23, and at this time, the TWS Bluetooth modules 23 on different devices can be interconnected. Specifically, the TWS Bluetooth module 23 at the mobile terminal device can be wirelessly connected to the TWS Bluetooth modules 23 in the vehicle system and the audio system. On this basis, by configuring an application software on the mobile terminal device and operating the application software, the device can be controlled to turn on / off, switch songs, play / pause, and the like, and the audio systems on the vehicle and the backrest body 1 can be controlled to sound synchronously.

[0061] Based on the above structure, by configuring the Bluetooth module 23 as a TWS Bluetooth module 23, on the one hand, the car audio can be made to sound synchronously through interconnection, improving the acoustic effect of the car audio system and supplementing the sound in the vehicle; on the other hand, the application software on the mobile terminal device can be used to control the audio system of the present embodiment, and the use convenience of the backrest audio is optimized and improved.

[0062] Optionally, referring to Figure 4 The backrest audio can also have a call function. Specifically, the Bluetooth module 23 can be a voice Bluetooth module 23, and at this time, the audio system further includes a voice collection module 24 for collecting voice information. The voice collection module 24 is usually a microphone element, and the voice collection module 24 is electrically connected to the voice Bluetooth module 23.

[0063] It can be understood that the voice Bluetooth module 23 is a Bluetooth module 23 specially designed for audio transmission and voice call function, which can support two-way transmission of voice (i.e., listening and speaking), and usually includes a microphone interface and a speaker output function, and supports HFP and HSP protocols.

[0064] Based on the above structure, by adopting the voice Bluetooth module 23, the call function of the headrest sound box can be realized, avoiding manual operation while driving, improving driving safety. It can be understood that the TWS interconnection function and the call function of the Bluetooth module 23 do not conflict with each other. In one embodiment, a Bluetooth module 23 that simultaneously considers the above two functions can be used. The specific model and structure of the Bluetooth module 23 are not limited here.

[0065] Further, the vehicle-mounted intelligent headrest sound box in the embodiment can also realize the start and stop of the sound system by voice control.

[0066] Specifically, referring to Figure 5 , the sound system further comprises a voice collection module 24 and a voice control module 25. The voice collection module 24 is arranged on the headrest body 1 and is usually a microphone element for collecting voice information. At the same time, the voice collection module 24 is arranged on the circuit board and is powered through the circuit board. At the same time, the voice control module 25 is electrically connected with the voice collection module 24 and the main control chip 22. It can be understood that the core component of the voice control module 25 is a voice control chip, which is a chip that can realize digital signal processing technology, also known as a DSP (Digital Signal Processing) chip, for acquiring, recognizing and processing voice information.

[0067] Based on the above structure, when the user issues a voice instruction, the voice collection module 24 can collect the instruction and generate voice information. The voice information is sent from the transmitting end of the voice collection module 24 to the receiving end of the voice control module 25. The voice control module 25 generates a processing result based on the voice information. Then the processing result is sent from the transmitting end of the voice control module 25 to the receiving end of the main control chip 22. The main control chip 22 then controls the vibration speaker 21 and the moving coil speaker 28 to sound based on the processing result. In the above process, the vibration speaker 21 and the moving coil speaker 28 can perform sound operations including but not limited to turning on and off, switching songs, playing and pausing, etc. under the action of voice control. Here, the voice control greatly improves the convenience of the headrest sound box during use.

[0068] Referring to Figure 6 , in another embodiment provided in the present application, the sound system can also obtain audio input through wired connection. Specifically, the sound system further comprises an AUX module 26, which is installed on the circuit board. The AUX module 26 is electrically connected with the main control chip 22.
