In order to achieve the purpose, the utility model provides a wireless music U-shaped pillow, which comprises a U-shaped pillow core, a resonance sounding module, a main control board and a power supply; the resonance sounding module comprises an electromagnetic exciter and a vibration sounding board; the electromagnetic exciter is fixedly connected with the vibration sounding board and is jointly arranged in the U-shaped pillow core; the resonance sounding module and the power supply are respectively electrically connected with the main control board; the main control board is integrated with a wireless communication module.

Furthermore, a protective sleeve wrapping the electromagnetic exciter and the vibration sound-producing board is further arranged in the U-shaped pillow core.

Further, the protective sheath is the silica gel protective sheath.

Furthermore, a power amplifier driving circuit is integrated on the main control board, and a power amplifier output interface of the power amplifier driving circuit is connected with an interface of the resonance sounding module.

Furthermore, the wireless communication module is a bluetooth module.

Further, the main control board is still connected the operation panel electrically, be equipped with at least one in wireless connection status display lamp, the interface that charges, speaker, the music broadcast control key on the operation panel.

Further, the music play control key includes at least one of a start key, a pause key, an end key, and a switching key.

Compared with the prior art, the utility model discloses a following beneficial effect has: the resonance sound production module is ingeniously arranged in the U-shaped pillow, wireless communication can be achieved with external equipment such as a mobile phone, the pillow core is used as a sound transmission medium, a user can listen to music by wearing the U-shaped pillow without an earphone, damage to ears caused by the earphone is avoided, and health entertainment is achieved. Meanwhile, the technical limitation that the traditional loudspeaker cannot be implanted into the U-shaped pillow is broken through, and the music function is added on the premise that the function of the U-shaped pillow is not influenced.

Detailed Description

The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand the invention and to implement the invention, and are not intended to limit the scope of the invention in any way.

Referring to fig. 1-5, an embodiment of the present invention provides a wireless music U-shaped pillow, which includes a U-shaped pillow core 1, a resonance sound module 2, a main control board 3 and a power supply. The resonant sound generation module 2 includes an electromagnetic exciter 21 and a vibrating sound generation panel 22. The electromagnetic exciter 21 and the vibration sound generation panel 22 are fixed together by adhesion or the like. The electromagnetic exciter 21 and the vibration sound-producing plate 22 are arranged in the U-shaped pillow core 1, and when the vibration sound-producing plate 22 vibrates, the vibration sound-producing plate serves as a medium for transmitting vibration signals through the U-shaped pillow core 1. The resonance sound production module 2 and the power supply are respectively electrically connected with the main control board 3, specifically, the electromagnetic exciter 21 in the resonance sound production module is electrically connected with the main control board 3, and the electric connection mode can adopt an electronic cable. The main control board 3 is further integrated with a wireless communication module (not shown in the figure). Outside music playback devices such as smart mobile phone, panel computer can realize communication connection through the wireless communication module of self and main control board 3, give main control board 3 with audio signal transmission, and main control board 3 further transmits the signal for resonance sound production module 2, and resonance sound production module 2 converts audio signal into mechanical vibration signal to U type pillow core is the sound production medium, and the sound production of vibration air is played the music, makes the user who wears U type pillow can listen to the music.

Compared with a driving horn, the electromagnetic exciter 21 and the vibration sound-producing plate 22 have small volume, can be smoothly placed in the pillow core, skillfully borrows the pillow core to transmit sound (namely vibration signals), and does not need to wear an earphone additionally. In this embodiment, the electromagnetic exciter has the following types: JM-ET-P190030305-03K4F01-U, and the vibrating plate is 31mm acrylic plate.

When a user uses the U-shaped pillow, the U-shaped pillow may deform under the action of external force such as stretching and squeezing, in order to reduce or avoid the damage of the deformation to the electromagnetic exciter 21 and the vibration sound-emitting plate 22, a protective sleeve 23 wrapping the electromagnetic exciter and the vibration sound-emitting plate is further arranged in the U-shaped pillow core, and the protective sleeve 23 may be a silica gel protective sleeve.
