[0031] like Figure 1 、 Figure 2 FIG2 is a schematic diagram of a bone conduction music pillow according to an embodiment of the present invention, which can be used as a pillow during sleep and also plays music. The bone conduction music pillow according to this embodiment includes a pillow body 10, a first bone conduction speaker 31, a second bone conduction speaker 32, a pressure sensor, and a main control circuit board. The first bone conduction speaker 31, the second bone conduction speaker 32, and the pressure sensor are each mounted within the pillow body 10, and are each electrically connected to the main control circuit board.

[0032] The pillow body 10 can be made of a soft elastic material such as memory foam or latex, and the upper surface of the pillow body 10 has a neck pillow area 11, a headrest area 12, a left sleeping area 13 and a right sleeping area 14, wherein the left sleeping area 13 and the right sleeping area 14 are respectively arranged in the first direction of the headrest area 12 (i.e. Figure 1 The neck pillow area 11 is located on both sides of the headrest area 11 in the second direction (i.e. Figure 1 The headrest area 12, the left sleeping area 13 and the right sleeping area 14 can be respectively formed by grooves on the upper surface of the pillow body 10, wherein the shape of the headrest area 12 is adapted to the shape of the back of the human head, and the edges of the headrest area 12 are respectively connected to the left sleeping area 13, the right sleeping area 14 and the neck pillow area 11 (the connection is an arc or a slope). The width of the left sleeping area 13 and the right sleeping area 14 is 10 to 20 cm (such as Figure 1 The width of the neck pillow area 11, headrest area 12, left sleeping area 13, and right sleeping area 14 is approximately 1:2. Of course, in actual use, the dimensions of the neck pillow area 11, headrest area 12, left sleeping area 13, and right sleeping area 14 can be adjusted based on the user population of the bone conduction music pillow, and will not be further elaborated here.

[0033] The first bone conduction speaker 31 is located below the left sleeping area 13, and the second bone conduction speaker 32 is located below the right sleeping area 14. The first bone conduction speaker 31 and the second bone conduction speaker 32 are independent of each other and each include a bone conduction vibrator which enables a user to perceive sound by transmitting vibration to the human head and then to the auditory ossicles. In actual applications, the first bone conduction speaker 31 and the second bone conduction speaker 32 can adopt conventional structures in the art, which will not be described herein.

[0034] A pressure sensor (not shown in the figure) is installed in the pillow body 10 and generates a corresponding output signal according to the pressure on the upper surface of the pillow body 10. That is, when the user's head is located at different positions of the pillow body 10, the output signal of the pressure sensor is different. Through the pressure sensor, the position of the user's head on the pillow body 10 and the head posture, etc. can be confirmed. The pressure sensor can adopt conventional devices in the art, which will not be described herein.

[0035] The main control circuit board is used to control the first bone conduction speaker 31 and the second bone conduction speaker 32 to sound. The main control circuit board can determine the position and posture of the user's head on the pillow body 10 according to the output signal of the pressure sensor, and output corresponding control signals (i.e. the current driving the vibration of the vibrator in the bone conduction speaker) to the first bone conduction speaker 31 and the second bone conduction speaker 32 according to the position and posture of the user's head on the pillow body 10. Specifically, when the main control circuit board confirms that the head is not located on the pillow body 10, it does not output any control signal to the first bone conduction speaker 31 and the second bone conduction speaker 32; when the main control circuit board confirms that the head is located in the left sleeping area and is side sleeping, it only sends a control signal to the first bone conduction speaker 31 below the left sleeping area 13, so that the first bone conduction speaker 31 plays music, while the second bone conduction speaker 32 does not play music; when the main control circuit board confirms that the head is located in the headrest area, it simultaneously outputs control signals to the first bone conduction speaker 31 and the second bone conduction speaker 32, so that the first bone conduction speaker 31 and the second bone conduction speaker 32 play music at the same time. In addition, when the main control circuit board confirms that the head is located in the headrest area of the pillow body 10 and is supine sleeping, the control signals output to the first bone conduction speaker 31 and the second bone conduction speaker 32 can be adjusted according to the distance between the head and the left sleeping area 13 and the right sleeping area 14, so that the first bone conduction speaker 31 and the second bone conduction speaker 32 play music at different volumes.

[0036] The bone conduction music pillow features a first bone conduction speaker 31 and a second bone conduction speaker 32 located below the left and right sleeping areas 13 and 14 of the pillow body 10, respectively. A main control circuit board controls the first and second bone conduction speakers based on pressure sensors built into the pillow body 10 to play music. This allows for music playback tailored to the user's sleeping position without disturbing others. Compared to placing two bone conduction speakers directly below the headrest area 12, this significantly increases the area over which the user can hear music. Even when resting their head on the edge of the pillow body, the user can still hear the music, resulting in a significantly better experience.

[0037] To ensure that the first and second bone conduction speakers 31, 32 maintain their positions within the pillow body 10, in one embodiment of the present invention, the pillow body 10 includes first and second positioning members (not shown). These members are harder than the pillow body 10, with the first positioning member positioned below the left sleeping area 13 and the second positioning member positioned below the right sleeping area 14. The first bone conduction speaker 31 is mounted on the first positioning member, with its vibrating surface protruding from or flush with the upper surface of the first positioning member. The second bone conduction speaker 32 is mounted on the second positioning member, with its vibrating surface protruding from or flush with the upper surface of the second positioning member. The relatively large size of the first and second positioning members (larger than the first and second bone conduction speakers 31, 32) prevents displacement of the first and second bone conduction speakers 31, 32 when subjected to external forces.

[0038] In one embodiment of the present invention, the upper surfaces of the left and right sleeping areas 13 and 14 each have a receiving groove. A first positioning member and a second positioning member are positioned within the receiving grooves in the left and right sleeping areas, respectively. The shapes and dimensions of the receiving grooves match those of the first and second positioning members. Accordingly, the bone conduction music pillow also includes a surface layer that covers at least the neck support area 11, head support area 12, left and right sleeping areas 13, and 14 on the upper surface of the pillow body 10. This structure allows the first and second bone conduction speakers 31, 32 to be closer to the user, facilitating their enjoyment of music.

[0039] Furthermore, to enhance comfort, the vibration surfaces of the first and second bone conduction speakers 31, 32 are each coated with a conductive member made of a flexible material. For example, the conductive member can be made of a material such as silicone. This ensures that the timbre and resonance intensity of the first and second bone conduction speakers 31, 32 are not significantly altered.

[0040] In one embodiment of the present invention, the bone conduction music pillow further includes a main unit 20, independent of the pillow body 10, with a main control circuit board located within the main unit 20. Accordingly, the main control circuit board is provided with a first interface and a second interface. The main control circuit board is electrically connected to the pressure sensor within the pillow body 10 via a cable connected to the first interface, and is electrically connected to the first bone conduction speaker 31 and the second bone conduction speaker 32 within the pillow body 10 via cables connected to the second interface, respectively. In this embodiment, both the control unit and the power supply are located within the main unit 20, thereby minimizing the impact of the electronic components on the user of the bone conduction music pillow.

[0041] Specifically, if Figure 3 、 Figure 4 As shown, the above-mentioned main control circuit board includes an audio decoding circuit and an audio output circuit; the audio decoding circuit includes a chip U3, which is electrically connected to the first interface J14 and receives a feedback signal from the pressure sensor through the first interface J14, and then generates an audio signal corresponding to the feedback signal of the pressure sensor (specifically including signals about the audio, amplitude, etc. of the first bone conduction speaker 31 and the second bone conduction speaker 32); the audio output circuit includes a chip U1, which is electrically connected to the audio decoding circuit and the second interface J2 and J3 respectively, and converts the audio signal from the audio decoding circuit into an analog voltage signal and outputs it through the second interface J2 and J3, so that the first bone conduction speaker 31 and the second bone conduction speaker 32 vibrate and sound respectively.

[0042] In particular, the pressure sensor may be located below the neck pillow area 11 , thereby helping the audio decoding circuit to determine the position and posture of the head.

[0043] like Figure 2 As shown, in one embodiment of the present invention, a main control circuit board 33 is housed within the pillow body 10 and includes an audio input interface exposed on the pillow body surface. This interface electrically connects the main circuit board to an audio playback device. In this embodiment, the main control circuit board also controls the first and second bone conduction speakers 31 and 32 to produce sound based on feedback signals from the pressure sensor. Unlike a main control circuit board built into the main unit 20, this embodiment allows the main circuit board to connect to any music playback device, such as an MP3 player or mobile phone, via the audio input interface, providing greater scalability.

[0044] In order to further improve the accuracy of sleeping posture judgment, the above-mentioned bone conduction music pillow includes multiple pressure sensors, which are respectively arranged below the headrest area, the left sleeping area and the right sleeping area, and the multiple pressure sensors are electrically connected to the main control circuit board through cables passing through the pillow body.

[0045] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
