Embodiment Construction

[0037] 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.

[0038] 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.

[0039] like Figure 1 to Figure 7 As shown, the ultrasonic sounder of the present invention includes a vibrating body 1 and a sounding driver 2. The sounding driver 2 drives the vibrating body 1 to vibrate by loading an ultrasonic signal, and the ultrasonic signal is self-demodulated in the air to generate audible sound, thereby realizing the vibration of the vibrating body. 1 directional sound. Since the directivity of the ultrasonic signal is obviously due to the audible s...

Abstract

The invention discloses an ultrasonic sound generator, a display and electronic equipment, the ultrasonic sound generator comprises a vibrating body and a sound production driver, the sound production driver comprises a conductive circuit and a magnetic circuit unit, and the magnetic circuit unit comprises a plurality of magnetic steels which are distributed at certain intervals and arranged in multiple rows. Magnetic poles of two corresponding ends of two adjacent pieces of magnetic steel are opposite, the conductive circuit is attached to the vibrating body, a vibrating space is arranged between the vibrating body and the magnetic circuit unit, the conductive circuit is wired in a gap formed between the magnetic steel, and the wiring mode of the conductive circuit in the gap enables the conductive circuit to pass through the vibrating space after an audio modulated ultrasonic signal is loaded on the conductive circuit. And the sounding driver is driven to generate vibration perpendicular to the plane where the vibrator is located, so that the vibrator is driven to vibrate and sound. According to the invention, by adjusting the wiring structure of the conductive circuit, the size of the gap between the magnetic steels, the driving frequency and the like, segmentation vibration can be reduced while high directivity of screen sound production is realized.

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 object of the present invention is to provide an ultraso...
