Abstract

The audio equipment comprises a loudspeaker, two input terminals and a control module, the loudspeaker comprises a magnetic circuit system and a vibration system, one end of a voice coil of the vibration system is connected with a vibrating diaphragm, the other end of the voice coil of the vibration system is inserted into a magnetic gap of the magnetic circuit system, the voice coil comprises two voice coil wires, and the two voice coil wires are arranged in the magnetic circuit system. The two voice coil wires are respectively provided with a first coil section and a second coil section, the first coil sections and the second coil sections are sequentially arranged in the axial direction of the magnetic gap, the current direction in the first coil sections is opposite to the current direction in the second coil sections, and the two input terminals are electrically connected with the two voice coil wires respectively and used for inputting current to the voice coil. The control module is electrically connected with the two input terminals, and the control module is used for controlling the two input terminals to switch the connection state and/or the current magnitude of the two voice coil wires. The invention aims to provide the audio equipment capable of eliminating the reverse electromotive force of the voice coil, and the audio equipment can effectively reduce distortion, improve loudness and improve subjective audition quality.

Description

technical field [0001] The invention relates to the technical field of electro-acoustic conversion, in particular to an audio device. Background technique [0002] With the rapid development of science and technology, people have higher and higher requirements for the sound quality of audio equipment. The sound-emitting device in the audio equipment is affected by the appearance and structure of the electronic equipment, and its volume is getting smaller and smaller. As an important and indispensable functional component of electronic equipment, the sound-emitting device uses a magnetic circuit system to drive the vibration of the voice coil, so that the sound-emitting device radiates more sound outward. However, in the related art, under the same power of the sound-generating device, a back electromotive force will be generated by passing a current into the voice coil, which will cause distortion of the sound-generating device and reduce the loudness and subjective listenin...
