Improved vibrating system for flat-plate loudspeaker

Abstract

The invention provides an improved flat type loudspeaker vibrating system, which includes a flat vibrating plate and a speech coil which is installed under the vibrating plate, and a round via hole is formed on the installation position of the speech coil of the vibration plate, and the speech coil is installed and fixed on the side wall of the via hole. The speech coil with and integrated structure of the sound file on the top of the speech coil and the speech framework, such as an aluminum cylinder with top is used as the framework of the speech coil, and the sound film is directly form on the top surface. The loudspeaker vibrating system not only can be easily assembled, but also has identical firm combination of the sound film and the speech coil, thereby improving the high-end frequency response further and ensuring the consistency of the loudspeaker performance.

Description

technical field [0001] The invention relates to the improvement of the vibration system of a flat-panel electric loudspeaker. Background technique [0002] At present, due to the rise of flat-panel TVs, the demand for matching flat-panel or thin speakers is obviously high. Thin speakers designed with traditional speakers are first of all thick, generally above 6cm, and difficult to match with flat-panel TVs. Second, they are heavy and difficult to install on the wall. For this reason, we propose a new design (patent application number: 200610122444.8) called "vibration system of a flat-panel electric loudspeaker", from which a thin flat-panel loudspeaker that can basically cover all audio frequency bands can be designed, and In this way, a full-band thin flat-panel speaker is manufactured. The invention is to dig a recess or a through hole in the middle of the traditional flat vibration plate, and this recess is just used to install the voice coil. If a through hole is du...

Problems solved by technology

[0006] The problem with the design of the above through hole scheme is that the vibration system needs to be composed of three components: a flat vibration plate with a through hole, and a thin film sound film (there are two methods: the top of the through hole is partially covered with the sound film or the entire vibration plate is covered with the sound film). membrane), voice coil

[0007] This requires three components to be assembled together, especially the combination of the voice coil and the sound film will seriously affect the high-end frequency response and consistency, and the process is difficult to operate
