Abstract

The invention discloses a loudspeaker. The loudspeaker comprises a magnet, wherein the magnet is used for generating a magnetic field; at least two coil groups, wherein the at least two coil groups are used for enabling current to flow by so as to move under the action of the magnetic field, and the at least two coil groups are further electrically connected with a controller to accept the control of the controller; a voice diaphragm, wherein the voice diaphragm comprises a middle area and a surrounding area located on the surrounding of the middle area, and the at least two coil groups are connected to different positions on the voice diaphragm; and a piezoelectric sensor, wherein the piezoelectric sensor is arranged on the voice diaphragm to detect the vibration of the middle area of the voice diaphragm and the vibration of the surrounding area of the voice diaphragm, and the piezoelectric sensor is electrically connected with the controller. The invention further discloses a mobile terminal, a control method and a computer readable medium.

Description

technical field [0001] The present invention relates to the technical field of electro-acoustic transduction, in particular to a loudspeaker, a mobile terminal, a control method and a computer-readable medium. Background technique [0002] The loudspeaker, commonly known as the horn, is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. A loudspeaker usually includes a magnet, a coil, and a sound membrane connected to the coil. The sound membrane vibrates under the electromagnetic motion of the coil to produce sound. However, existing speakers cannot detect and balance the diaphragm. Contents of the invention [0003] The main purpose of the present invention is to provide a speaker capable of detecting and balancing a sound film, a mobile terminal, a control method and a computer readable medium. [0004] To achieve the above object, an embodiment of the present invention provides a loudspeaker, including: a...
