Embodiment Construction

[0044] Specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0045] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0046] Such as Figure 1 to Figure 9 As shown, an ultrasonic sounder disclosed by the present invention includes a vibrating body 1, a supporting body 2, and a sounding driver 3 located between the vibrating body 1 and the supporting body 2, and the sounding driver 3 drives the vibrating body 1 to vibrate by loading an ultrasonic signal, In addition, the ultrasonic signal is self-demodulated in the air to generate audible sound, thereby realizing directional sound emission by...

Abstract

The invention discloses an ultrasonic sound generator, a display and an electronic device, the ultrasonic sound generator comprises a vibrating body and a sound production driver, the sound production driver comprises a plurality of vibrating units arranged on the vibrating body, the plurality of vibrating units are arranged on the vibrating body in an array, an air gap is arranged between each vibrating unit and the vibrating body, and the air gap is arranged between each vibrating unit and the vibrating body. The distance between every two adjacent vibration units ranges from 2 mm to 100 mm, and the size of each vibration unit ranges from 1 mm to 100 mm. The sound production driver loads an ultrasonic signal, generates vibration perpendicular to the direction of the vibration body, and drives the vibrator to vibrate and produce sound. By adjusting the arrangement mode of the vibration units of the sound production driver, the size of the vibration units, the distance between the vibration units, the frequency of the ultrasonic signal and the like, sound distortion caused by segmentation vibration is avoided, the overall vibration amplitude of the sound production device can be reduced, the reliability of the whole sound production device is improved, and the sound production device is not prone to being broken or stripped.

Description

technical field [0001] The invention relates to the technical field of ultrasonic sound generation, in particular to an ultrasonic sounder, a display and electronic equipment. Background technique [0002] With the development of the portable consumer electronics market, screen sounders have gradually entered the sight of more and more people due to their larger screen ratio, such as mobile phones, computers, TVs, photo frames, and multimedia players. Wait. [0003] The traditional screen sound is to use a vibrator to directly drive the entire electronic device screen, and then achieve the sound effect through the screen vibration. However, this method will inevitably have a high amplitude, which requires high reliability of the entire screen sounder, and is prone to failures such as breakage or peeling. Therefore, the present invention proposes a new solution to solve this problem. Invention content: [0004] The purpose of the present invention is to provide an ultras...
