Abstract

The invention provides a multi-voice-coil based loudspeaker system. The multi-voice-coil based loudspeaker system comprises a loudspeaker and a driving portion; the loudspeaker comprises a vibrating diaphragm and a voice coil assembly; the voice coil assembly comprises a detection voice coil and a driving voice coil; the driving voice coil is used for driving the vibrating diaphragm to perform electric-acoustic converting; the detection voice coil is connected to the vibrating diaphragm to be used for detecting working states of the loudspeaker and obtain corresponding detection information; the driving portion is connected to the driving voice coil and the detection voice coil to be used for collecting detection information from the detection voice coil, calculating working state parameters of the loudspeaker and adjusting the working state parameters of the loudspeaker to be safe working parameters when the working state parameters exceed the safe working parameters.

Description

technical field [0001] The present invention relates to a loudspeaker technology, in particular, to a multi-voice coil based loudspeaker system. Background technique [0002] With the development of electronic technology, many portable mobile electronic devices (such as mobile phones, tablet computers, portable multimedia players, etc.) are more and more widely used in consumers' daily life. Generally speaking, in order to satisfy users' needs for audio, mobile electronic devices are generally equipped with speaker systems to convert electrical signals into audio signals, and output the audio signals for users to listen to. [0003] A loudspeaker system related to this application adopts a single voice coil structure, that is, a separate voice coil is set inside the loudspeaker to drive the diaphragm to realize electro-acoustic conversion. circle to work. However, since there is only a single voice coil inside the speaker system, it is difficult to accurately detect and an...
