Background
The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the quality of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the paper cone or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through electromagnetic, piezoelectric or electrostatic effect to make sound.
The sound emitted by a conventional loudspeaker is transmitted in all directions, and the diameter of the loudspeaker must be very large to achieve directivity. The diameter of the loudspeaker is large, and the phenomenon of disturbing residents is easily generated when the transmitted sound is amplified and emitted into the air.
The existing directional loudspeaker is generally in a fixed direction, if the direction is adjusted, the installation direction needs to be changed, and the projection direction cannot be automatically changed.
