Abstract
The present invention provides a multifunctional electromagnetic transducer including: a housing providing with a sound port and a speaker fixed with the housing. The speaker includes a frame forming an accommodating cavity cooperatively with the housing, a vibration system supported on the frame and received in the accommodating cavity; and a magnetic circuit system received in the accommodating cavity driving the vibration system to vibrate along a first direction and generate sounds. The multifunctional electromagnetic transducer further includes a flexible support disposed on a side of the magnetic circuit system distal to the vibration system and secured to the housing. The magnetic circuit system is suspended in the accommodating cavity by the flexible support and moves along the first direction.
