A multifunctional electromagnetic transducer includes a bracket, a vibrating unit including a magnetic circuit part receiving in the bracket, and a plurality of helical wound springs assembled to the bracket for sustaining the magnetic circuit part. The magnetic circuit part defines a pole plate, a first magnet disposed at a center portion of the pole plate, and a plurality of second magnets surrounding the first magnet and forming a magnetic gap corporately with the first magnet. Each of the second magnets forms a receiving gap corporately with an adjacent second magnet. A voice coil is partially inserted into the magnetic gap.

Electromagnetic transducer

An electroacoustic transducer is disclosed. The electroacoustic transducer includes a frame forming a hollow space, an elastic plate mounted on the frame, a vibrating member suspended in the hollow space by the elastic plate, a diaphragm arranged facing the vibrating member, a voice coil positioned on the diaphragm. The vibrating member includes a yoke defining a bottom wall, a side wall extending upwardly and perpendicularly from an outer periphery of the bottom wall, a lapel extending vertically from the side wall. A width of the lapel is greater than that of the side wall or the bottom wall.

Electroacoustic transducer

A multi-function vibrating device is disclosed. The multi-function vibrating device providing sound producing and vibration functions includes a holder having a hollow space, a suspension divided into at least two parts, a vibration member suspended by the suspension and having at least a pair of receiving concaves for fixing the corresponding two parts of the suspension. The multi-function vibrating device has larger vibrating amplitude and small size.

Multi-function vibrating device

The present invention provides a magnet assembly and speaker including such a magnet assembly. The magnet assembly includes an outer magnet defining a pair of first plat magnets, an inner magnet surrounded by the outer magnet and defining a pair of second plat magnets, a first magnetic gap formed between an inner surface of the outer magnet and an outer surface of the inner magnet, and a magnetic conductive portion sandwiched between the pair of the second plat magnets. A width of the magnetic conductive portion is unequal to a length of the outer and inner magnets. Polarity of the pair of the first plate magnets adjacent to the magnetic gap is similar to each other. Polarity of the pair of the first plate magnets adjacent to the magnetic gap are opposite to that of the pair of the second plate magnets adjacent to the first magnetic gap.
