Embodiment Construction

[0017] The sound generating device of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] see figure 1 , The first embodiment of the present invention provides a sound generating device 100, which includes a fixing frame 11 and a sound generating module 12, and the fixing frame 11 clamps and fixes the sound generating module 12 therebetween.

[0019] see figure 2 , the fixed frame 11 includes two frame bodies 110 located on both sides of the sound module 12, and the two frame bodies 110 are interlocked to sandwich the sound module 12 therebetween. The two frame bodies 110 can also be connected by means of screwing, bonding, riveting and the like.

[0020] The two frames 110 have the same structure and are arranged symmetrically with respect to the sound module 12. Each frame 110 is surrounded by four frames connected end to end, and the four frames are surrounded by an opening 111, and the opening 1...

Abstract

The invention relates to a sounding module which comprises a base plate and a cover plate, wherein the base plate and the cover plate are opposite to each other; at least one first electrode and at least one second electrode area arranged on the base plate; and a thermal sounding film is laid on and electrically connected to the at least one first electrode and the at least one second electrode. The thermal sounding film of the thermal sounding module is sealed and fixed by the base plate and the cover plate, and thus, a complete module structure with the thermal sounding film is formed. Both opposite sides of the thermal sounding film in the thermal sounding module are respectively protected by the base plate and the cover plate, and the thermal sounding film works in a space formed by the base plate and the cover plate and reduces the damage to the external environment, thereby prolonging the service life of the thermal sounding film.

Description

technical field [0001] The invention relates to a sounding module and a sounding device using the sounding module. Background technique [0002] Traditional sounding modules, such as electric, electromagnetic, electrostatic, piezoelectric, ionizing, and pneumatic sounding devices, mostly use a diaphragm as the sounding element. In order to enable the diaphragm to vibrate and produce sound, the sound emitting module not only needs to be provided with a space for the diaphragm to vibrate, but also needs to be provided with a vibration driver with a complex structure to drive the diaphragm to vibrate. Therefore, the packaging structure of the sound generating module is relatively complicated and not compact enough. [0003] Fan Shoushan and others disclosed a new sounding element on October 29, 2008, which is a thermal sounding membrane. Please refer to the literature "Flexible, Stretchable, Transparent Carbon Nanotube Thin Film Loudspeakers", Fan et al., Nano Letters, Vol.8(...
