Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a controller for a plane wave loudspeaker. Background Art

[0002] Speakers are commonly known as "horns". They are a very commonly used electroacoustic transducer. Speakers are transducers that convert electrical signals into acoustic signals. The performance of speakers has a great impact on the sound quality. Speakers are the weakest component in audio equipment, but they are also the most important component for sound effects. There are many types of speakers, and their prices vary greatly. Audio electrical energy vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects, and resonates (resonates) with the surrounding air to produce sound;

[0003] Traditional speakers use crossovers to divide the speakers into tweeters, mid-range and bass, but the sound itself is mixed, and playing it after dividing it will cause distortion and affect the speaker effect. Utility Model Content
