The application discloses a picture frame sound box comprising a multilayer vibration plate, which comprises a picture frame; a vibration plate and a sub-vibration plate, which are installed in the picture frame and enclosed to form an acoustic cavity; and a drive horn arranged on the vibration plate and configured to drive the vibration plate to vibrate and sound by mechanical vibration, and the drive horn does not directly sound itself. The application realizes a picture frame sound box structure, which sounds by flat plate vibration, and the vibration plate and the sub-vibration plate are used to form an acoustic cavity, so that the sound quality and sound effect can be improved, and thinning can be realized.

The invention provides a bass enhancement device and a sound box, and relates to the technical field of sound quality enhancement. The bass enhancement device comprises a body, at least one sound dividing assembly and an expansion piece. A cavity is formed in the body, a mounting part and at least one sound emitting part are arranged on the body, and the mounting part is communicated with the cavity; the sound dividing assembly is arranged in the cavity and is provided with a propagation channel, the two ends of the propagation channel are communicated with the cavity and the sound output part respectively, and the propagation channel is arranged around the axis of the mounting part; the expansion member is disposed within at least one of the propagation channel and the cavity. Coupling resonance among the propagation channel, the cavity and the generating part is utilized to enhance sound waves radiated to the front side by the vibrating diaphragm of the sound generating part; sound waves on the back of the diaphragm are propagated to the outside through the propagation channel to further enhance bass; and finally, the resonant frequency is reduced through a small number of expansion pieces, and the bass is further enhanced, so that a better bass effect is obtained.

The utility model belongs to the technical field of sound boxes, and particularly relates to a sound box structure, which comprises a sound box main body and an integrated control unit arranged on the surface of the sound box main body, and the surface of the sound box main body is also provided with an audio interface female seat independent of the integrated control unit. According to the utility model, the long audio interface female seat is installed on the surface of the sound box main body and is independent of the integrated control unit, so that the overall thickness of the integrated control unit is reduced, and when the integrated control unit is installed with the sound box main body, the integrated control unit occupies a small space inside the sound box main body, thereby effectively improving the volume ratio inside the sound box main body, and improving the volume ratio of the sound box main body. Therefore, the bass effect of the loudspeaker box is improved.

This utility model discloses a speaker sound outlet cavity structure, including a sound outlet cavity, a speaker, and a pad. The speaker is installed at the upper end of the sound outlet cavity, and the pad is installed at the lower end of the sound outlet cavity. The upper side of the pad has several spaced-apart recesses. One side of the sound outlet cavity has a sound outlet. The speaker and the pad are vertically opposite each other, with the speaker's sound output direction facing the upper side of the pad. The sound emitted by the speaker is reflected by the upper side of the pad and the recesses of the pad before being output from the sound outlet. This utility model can further improve sound loudness and bass effect, and can make the emitted sound have a stereo surround sound effect.
