[0043] Here, in addition to the vibrating plate 20, other plate members can also be selected to be installed in the mounting groove 11 of the picture frame 10, for example, a decorative picture plate is arranged on the front, or a transparent glass or acrylic plate is arranged for holding photos or pictures inside. This is not limited herein.

[0044] Reference Figure 5Figure 1 shows a driving horn 30 according to an embodiment of the present application. The driving horn 30 includes a basket 38, a magnetic assembly 31 connected to the basket 38 by a resilient piece 32, and a vibrating assembly 33 connected to the basket 38 by a resilient wave 32; the magnetic assembly 31 and the vibrating assembly 33 vibrate together to form a double driving force.

[0045] In some embodiments, the resilient wave 32 is exposed to the basket 38.

[0046] In some embodiments, the vibrating assembly 33 can include a voice coil 33 connected to the resilient wave 32, and an adhesive ring 34 disposed on the voice coil 33, the adhesive ring 34 being used to fixedly connect to the vibrating plate 20, and the basket 38 and the vibrating plate 20 are not directly connected.

[0047] In some embodiments, the magnetic assembly 31 can include a U-shaped iron 35 connected to the resilient piece 32, a magnet 36 disposed in the U-shaped iron 35, and a dust cap 37 disposed above the magnet 36.

[0048] In some embodiments, the magnet 36 and the dust cap 37 have the same diameter, and the side surfaces of the magnet 36 and the dust cap 37 and the inner side wall of the U-shaped iron 35 form a gap for accommodating the voice coil 33, and the voice coil 33 can vibrate up and down in the gap.

[0049] In some alternative embodiments, the driving horn 30 can have a substantially flat disc shape when viewed from the top.

[0050] In some alternative embodiments, the outer edge of the resilient wave 32 is connected to the upper surface of the basket 38, and the inner edge of the resilient wave 32 is connected to the voice coil 33.

[0051] In some alternative embodiments, the resilient wave 32 has a wave shape and includes a plurality of wave portions.

[0055] Here, the driving horn 30 can achieve an ultra-thin structure, for example, can be made within 10 mm.

[0056] The working principle of the driving loudspeaker 30 includes that the 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), so that the voice coil 33 and the adhesive ring 34 arranged thereon generate vibration, and the magnetic assembly itself also generates vibration, the adhesive ring 34 drives the vibration plate 20 to generate vibration, and the vibration plate 20 restores the audio signal to sound through the vibration.

[0057] Reference is made to Fig. 1, which shows a driving loudspeaker 30 according to an embodiment of the present application. Figure 6 Similar to Fig. 1, the difference lies in that: Figure 6 Figure 5 In the driving loudspeaker 30 shown in Fig. 2, the height of the yoke 38 is reduced, and the height of the yoke 38 is less than the height of the U-shaped iron 35, so as to further reduce the thickness of the driving loudspeaker 30.

In this case, the magnetic assembly and the yoke 38 are integrated, and only the vibration assembly can vibrate relative to the yoke 38.

[0061] Reference is made to Fig. 6, which shows a driving loudspeaker 30 according to still another embodiment of the present application. Figure 8 Similar to Fig. 1, the difference lies in that: Figure 8 Figure 7

[0062] Figure 8 In the driving loudspeaker 30 shown in Fig. 7, the height of the yoke 38 is reduced, and the height of the yoke 38 is less than the height of the U-shaped iron 35, so as to further reduce the thickness of the driving loudspeaker 30. Figure 7 In the driving loudspeaker 30 shown in Fig. 8, the height of the yoke 38 is equal to or slightly higher than the height of the U-shaped iron 35.

[0063] In summary, the embodiment one of the present application proposes a picture frame sound box.

[0064] ​​​​​​The picture frame speaker utilizes a driving speaker 30 to drive the vibration plate 20, so that the vibration plate 20 makes sound 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 speaker 30 vibrate together to form a dual driving force, which is equivalent to two drives working together, which can greatly increase the driving force. Compared with ordinary dynamic speakers, the driving force can be increased by about 50%, thereby increasing the volume and improving the sound quality while achieving lightness and thinness. In addition, the sensitivity of this type of driving speaker 30 can be higher, much higher than that of ordinary speakers, and can play mid- and high-frequency audio. In this way, the picture frame speaker of the present application can play a variety of sounds in the full frequency band, such as various music, to achieve extremely high sound quality effects.

[0065] As mentioned above, the picture frame speaker of the present application can achieve extremely high sound quality and sound effects while being lightweight and thin; the picture frame speaker can replace traditional speakers, reduce the volume, and reduce space occupied; it can be hung on the wall as a hanging ornament; it can be embedded in paintings or photos; a Bluetooth module can be set up to be used as a Bluetooth speaker; it can be used for home karaoke; and so on.
