Directional Plasma Speakers

Abstract

The invention provides a directional plasma loudspeaker, which comprises a sound pipe made of a rigid sound-insulating material with a smooth inner surface, one end of the sound pipe is open, and the other end is blocked by an electrical box; The two output ends of the plasma speaker module are electrically connected to the two discharge electrodes opposite to the central axis of the sound tube. The loudspeaker can not only output relatively high-power music in a directional manner, but also has a small volume and is easy to carry.

Description

technical field [0001] The invention relates to the field of electric appliances, in particular, to a loudspeaker. Background technique [0002] With the increasing spiritual and cultural needs of people, square dancing has become a common form of entertainment among middle-aged and elderly people; however, serious noise is often produced during people's square dancing activities and playing music, which affects the relationship between neighbors; in order to deal with In this case, people sometimes use directional speakers to avoid disturbing people by controlling the direction of sound waves. [0003] The current directional speakers usually add sound-gathering covers to gather sound waves on the basis of ordinary speakers to achieve directional propagation effects. Therefore, when they provide output power that meets the needs of square dancing activities, they are relatively bulky and difficult to carry. Contents of the invention [0004] In view of the above problems...
