The invention relates to the technical field of acoustic components. The invention discloses a loudspeaker and a sound production device. The loudspeaker comprises: a basin frame; a magnet fixedly arranged at the bottom of the basin frame; a voice coil arranged in the basin frame and surrounding the periphery of the magnet and capable of moving relative to the magnet in the direction perpendicularto the bottom of the basin frame; a vibrating diaphragm connected to one end of the voice coil away from the magnet, having an edge connected with the basin frame and capable of sealing the basin frame, wherein one side of the vibrating diaphragm away from the voice coil is provided with a metal layer; a metal sheet which is connected to the basin frame and located on one side, deviating from thevoice coil, of the vibrating diaphragm, wherein a gap is formed between the metal sheet and the vibrating diaphragm, and air on the two sides of the metal sheet can circulate; and an IC chip, whereinthe metal sheet and the metal layer are connected with the IC chip, the IC chip can enable an electric field to be formed between the metal sheet and the metal layer, and the IC chip can collect a capacitance value between the metal sheet and the metal layer. The sound production device comprises a main board, a voice coil control chip and the loudspeaker. When the horn and the sound production device work, the amplitude of the vibrating diaphragm can be monitored in real time.
Description
technical field [0001] The invention relates to the technical field of acoustic components, in particular to a horn and a sounding device. Background technique [0002] The speaker is an important component of sound-generating devices (such as mobile phones, tablet computers, TVs, audio, etc.), and it mainly relies on the diaphragm to push the air to produce sound. If the diaphragm is damaged, it will not work properly. It can be seen that keeping the diaphragm from being damaged is particularly important for the normal operation of the speaker. [0003] As we all know, if the vibration amplitude of the diaphragm exceeds the limit it can withstand, it will be easily damaged. Therefore, during the working process of the speaker, try to ensure that the vibration amplitude of the diaphragm does not exceed the set limit value. However, in the prior art, the vibration amplitude of the diaphragm can only be tested by laser when the function of the speaker is tested before the spe...
