The material of the vibration plate 20 includes, but is not limited to, cardboard, aluminum plate, copper plate, plastic plate, and the like. In the embodiment of the application, the driving loudspeaker 30 drives the vibration plate 20 to vibrate and sound through mechanical vibration, so that the effect of bass (namely low-frequency sound) can be effectively increased compared with the mode of directly sounding by using the loudspeaker in a plate vibration sounding mode.

Here, in addition to the vibration plate 20, other plate members, such as a decorative drawing plate provided on the front surface or a transparent glass or acryl plate, may be optionally installed in the installation groove 11 of the picture frame 10 for internally holding a photograph or drawing. This is not limiting herein.

Referring to fig. 5, a driver horn 30 of one embodiment of the present application is shown. The driving horn 30 comprises a basin frame 38, a magnetic component which is connected with the basin frame 38 in a vibrating way through a spring piece 31 and a vibration component which is connected with the basin frame 38 in a vibrating way through a spring wave 32, wherein the magnetic component and the vibration component jointly vibrate to form a dual driving force.

Wherein the elastic wave 32 is exposed out of the basin stand 38.

Wherein, the vibration assembly may include a voice coil 33 connected to the damper 32 and an adhesive ring 34 disposed on the voice coil 33, the adhesive ring 34 being fixedly connected to the vibration plate 20, and the frame 38 and the vibration plate 20 being not directly connected.

Here, the driving speaker 30 operates on the principle that an audio signal is applied to the voice coil 33, the voice coil 33 generates an alternating magnetic field, the magnetic field generated by the voice coil 33 interacts with the fixed magnetic field of the permanent magnet (i.e., the magnet 26) to vibrate the voice coil 33 and the adhesive ring 34 provided thereon, and the magnetic assembly itself vibrates, and the adhesive ring 34 drives the vibration plate 20 to vibrate, so that the vibration plate 20 restores the audio signal to sound through the self vibration.

Referring to fig. 6, a drive horn 30 of another embodiment of the present application is shown. Fig. 6 is similar to fig. 5, except that:

In the driving horn 30 shown in fig. 6, the height of the basin stand 38 is reduced, and the height of the basin stand 38 is smaller than the height of the U-shaped iron 35, thereby further reducing the thickness of the driving horn 30. In the driving horn 30 shown in fig. 5, the height of the basin stand 38 is equal to or slightly higher than the height of the U-shaped iron 35, so that the vibration amplitude can be increased, and the driving force can be improved.

Referring to fig. 7, a drive horn 30 of yet another embodiment of the present application is shown. Fig. 7 is similar to fig. 5, except that:

In the driving horn 30 shown in fig. 7, the spring plate 31 is removed, and the magnetic assembly is directly connected to the basin frame 38, specifically, the U-iron 35 is directly connected to the basin frame 38.

In the driving horn 30 shown in fig. 7, the height of the basin stand 38 is equal to or slightly higher than the height of the U-iron 35.

In summary, the first embodiment of the application provides a frame loudspeaker box.

The picture frame speaker drives the vibration plate 20 by the driving horn 30 so that the vibration plate 20 sounds in a flat plate vibration manner, which can increase the effect of bass (low frequency sound). Here, the magnetic component and the vibration component in the driving horn 30 vibrate together to form a dual driving force, which is equivalent to the combined action of the two driving forces, and the driving force can be greatly improved, which can be improved by more than about 50% compared with the driving force of the common moving-coil horn, so that the volume and the sound quality can be improved while the light and thin driving horn is realized. In addition, the sensitivity of the driving loudspeaker 30 can be higher than that of a common loudspeaker, and middle-high pitch audio can be played. Therefore, the frame loudspeaker box can play various sounds in the full frequency range, such as various music, and achieves extremely high sound quality effect.

As above, the frame sound box can realize extremely high sound quality and sound effect and simultaneously realize light and thin structure, can replace the traditional sound box, can reduce volume and space occupation, can be hung on a wall to be used as hanging decorations, can be embedded with pictures or photos, can be provided with a Bluetooth module to be used as a Bluetooth sound box, can be used as a household K song, and the like.
