Description
Technical Field
The utility model relates to a speaker technical field especially relates to kinds of miniature speakers of high strength.
Background
At present, the high-strength micro loudspeaker and the receiver used by the mobile terminal are mostly moving-coil loudspeakers. The moving-coil loudspeaker comprises a magnetic circuit system, a vibration system and a basin frame for accommodating and fixing the magnetic circuit system and the vibration system. In order to increase the volume of the magnetic circuit system and increase the acoustic performance of the sounding device, the structure of the basin frame is reduced as much as possible, so that the structure of the basin frame is limited and the strength is not stable enough. Therefore, a washer needs to be injection-molded on the frame to enhance the structural strength of the frame. The washer is of an annular structure, and in the prior art, a double-magnetic-circuit structure or a triple-magnetic-circuit structure is adopted for increasing the output power of the electroacoustic transducer. The double magnetic circuit structure is a central magnetic steel positioned at the center of the basin stand and two side magnetic steels positioned at the edge of the basin stand. The three magnetic circuit structures are central magnetic steel positioned at the center of the basin stand and four side magnetic steels positioned at the edge of the basin stand. However, for the above-mentioned double magnetic circuit structure or triple magnetic circuit structure, there is a suction force between the central magnetic steel and the annular washer, and the bonding force between the annular washer and the plastic part of the frame is not strong, and especially under the action of external force, cracks are easily generated at the bonding edge of the annular washer and the frame, and even separation occurs in severe cases, so that the reliability of the high-strength micro-speaker is poor.
