AI Technical Summary
Technical Problem
The noise signal output by the driver chip is radiated through the shape memory alloy coil, affecting the communication performance and user experience of electronic devices.
Method used
A filter circuit is used to suppress the transmission of noise signals from the driver chip to the shape memory alloy coil. Low-pass, band-stop, or band-pass filter circuits suppress the noise signals outside the frequency band to avoid electromagnetic radiation.
Benefits of technology
This reduces the impact of noise signals on the radio frequency antenna, improving communication performance and user experience.

Abstract
The invention provides a motor, a lens module, a camera module and electronic equipment, and belongs to the technical field of electronic equipment. The motor comprises a driving chip, a first shape memory alloy coil and a first filter circuit. Wherein the first end of the first shape memory alloy coil is coupled with the first end of the driving chip through the first filter circuit, and the second end of the first shape memory alloy coil is coupled with the second end of the driving chip. The driving chip is used for controlling the first shape memory alloy coil to deform. According to the embodiment of the invention, the noise signal output by the first end of the driving chip is prevented from being transmitted to the first shape memory alloy coil through the first filter circuit, so that electromagnetic wave radiation generated when the noise signal is transmitted to the first shape memory alloy coil is improved and even avoided, and the influence of the noise signal on a radio frequency antenna is reduced; the sensitivity of the radio frequency antenna is guaranteed, and the communication effect and the user experience are improved.
