[0094] In other embodiments, the sound cavity 11A and the sound cavity 11B are respectively provided with modulators, the excitation diaphragm 1, the excitation diaphragm 2 and the excitation diaphragm 3 in the sound cavity 11A have different areas, and the excitation diaphragm 4, the excitation diaphragm 3 in the sound cavity 11B have different areas. The diaphragm 5 and the excitation diaphragm 6 have different areas, and the audio signals of the excitation diaphragms in the two sound chambers can be adjusted by the modulator to achieve balance. Of course, the number of excitation diaphragms in the two sound chambers can also be different, and the two sound chambers and the excitation diaphragms can also not be symmetrical with the support body, as long as the sound quality of each sound chamber can be guaranteed, and the overall stereo sound and sound quality can be realized. That is, we will not list them all here.

Abstract

The invention discloses a vibration sounding device and electronic equipment. The electronic equipment provided by the embodiment of the invention comprises a main body, a display screen arranged on the main body, and a sound production assembly, the sound production assembly comprises a sound cavity and an excitation diaphragm located in the sound cavity; the sound cavity is arranged in the mainbody, or is formed by the main body and the display screen; the main body is provided with a sound outlet hole corresponding to the sound cavity. The excitation diaphragm is fixed in the sound cavityand divides the sound cavity into two sub-cavities. The sound outlet hole is communicated with one of the sub-cavities, the excitation diaphragm generates vibration after receiving audio signals, andthe excitation diaphragm drives air in the two sub-cavities to vibrate through the vibration of the excitation diaphragm so as to achieve sound production and diffuse the sound through the sound outlet hole.

Description

technical field [0001] The invention relates to the technical field of sound generation, in particular to a vibration sound generation device and electronic equipment. Background technique [0002] With the development of technology and consumer demand, the external size of electronic equipment such as mobile terminals and displays is getting larger and larger, and its industrial design is getting thinner, especially for existing mobile phones. Higher and higher. The common sounding device in electronic equipment uses a micro-magnetic speaker and a micro-vibration motor to realize the horn function to produce sound, but this structure is complex, consumes a lot of energy, and takes up a lot of internal space, which limits the thin and light design of the product. Contents of the invention [0003] The application provides an electronic device and a vibration and sound device, which uses the vibration of the excitation diaphragm itself to drive the air in the sound cavity ...
