Abstract: Disclosed is a micro loudspeaker. The casing of the micro loudspeaker comprises an upper side surface and a lower side surface. An electric connecting piece comprises a first deformation part located on one side of the upper side surface of the casing and side bent upwards, a second deformation part located on one side of the lower side surface and side bent downwards, a connecting part electrically connecting the first deformation part and the second deformation part. The top end of the first deformation part and the bottom end of the second deformation part are respectively provided with a first conducting part and a second conducting part. An electronic device comprises a micro loudspeaker mentioned above, a shell, a first sound hole and a circuit board, wherein a first conducting part or a second conducting part of the micro loudspeaker is electrically connected to the circuit board.

Abstract: A miniature speaker comprises a first housing body and a second housing body, which are combined together. A vibrating system and a magnetic circuit system are accommodated in a space defined by the first housing body and the second housing body. The miniature speaker is characterized in that the sidewall at the end of the second housing body, which is combined with the first housing body, surrounds the periphery of the first housing body; a gap is provided between the outer edge of the first housing body and the inner side of the sidewall of the second housing body; the miniature speaker further comprises a sealing member which covers the first housing body, and the edge of the sealing member is located in the gap, which makes the gap between the first housing body and the second housing body sealed.

Abstract: Disclosed is an electroacoustic transducer, comprising a vibration system and a magnetic circuit system, wherein the vibration system comprises a vibrating diaphragm and a voice coil; and the magnetic circuit system comprises a yoke, a central magnet, and edge magnets; wherein, each edge magnet has a strip shape, limiting parts are provided at two corners of any edge magnet closer to a magnetic gap, and the yoke is provided with stoppers abutted against the limiting parts at positions corresponding to the limiting parts. Each edge magnet of the present invention is provided with limiting parts formed by removing material, and the yoke is provided thereon with stoppers for preventing the edge magnets from approaching the central magnet, so that a bad phenomenon due to the fact that the edge magnets and the central magnet are attracted to each other can be avoided, thereby increasing the yield of a product.
