Problems solved by technology

Therefore, the 3-30 mm flat-panel speakers cannot further meet the requirements of modern flat-panel televisions, and since most of the magnets in the above-mentioned flat-panel speakers adopt rare earth high magnetic materials, the products are not only expensive, but also consume rare resources.

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] see Figure 1 to Figure 4 , the panel loudspeaker of the present invention includes a diaphragm 1 and a piezoelectric device 2, and also includes an outer frame 3 having at least one open end. In this embodiment, the frame is preferably surrounded by a rectangular ring wall or a circular ring wall. The frame body, that is, the outer frame 3 is a rectangular outer frame, or the outer frame is a circular outer frame, so openings are formed at both ends thereof. The diaphragm 1 is located outside the outer frame and one end of the diaphragm is fixed on the opening end of the outer frame 3, that is, the diaphragm 1 is fixed on one of the opening ends of the outer frame 3, and one end of the piezoelectric device 2 is fixed on the outer frame 3. The membrane 1 is surrounded by the outer frame after being placed on it. Such a structure makes t...

Abstract

The invention relates to a panel loudspeaker. The panel loudspeaker comprises a vibrating diaphragm, a piezoelectric device and an outer frame with at least one opening end. The vibrating diaphragm is arranged on the outer part of the outer frame. One end of the vibrating diaphragm is fixed on the opening ends of the outer frame. One end of the piezoelectric device is fixed on the vibrating film and then is surrounded by the outer frame. A positive electrode conductive area and a negative electrode conductive area are arranged on the piezoelectric device. The positive electrode conductive area and the negative electrode conductive area are respectively connected with conductive electrodes. The panel loudspeaker is characterized in that the panel loudspeaker is ultra-thin and sound quality is high.

Description

technical field [0001] The invention relates to a flat panel loudspeaker. Background technique [0002] In existing flat-panel TVs, most of them use flat-panel speakers, such as figure 1 As shown, the flat-panel speaker is composed of one or more drivers (mainly electromagnetic and piezoelectric attached to a flat-panel speaker diaphragm) at a specific position. When the coil in the driver passes through the audio current, the driver will drive The planar vibrating plate generates wave-like vibrations to spread the sound. [0003] The flat-panel loudspeaker consists of four parts: driver body, vibration plate, suspension system and box body (back cover). [0004] 1) The driver is equivalent to the heart of the panel speaker, requiring small size and strong magnetic force. Magnets are mostly made of rare-earth high-magnetic materials, and sometimes more than two drivers are used to increase the output sound pressure, increase the output sound power and obtain a better freq...
