    摘要: Provided is a loudspeaker. The loudspeaker includes a shell, a vibration structure, a magnetic circuit structure, a voice coil and a bridging structure. The vibration structure is disposed on the shell. The magnetic circuit structure includes a yoke and a magnetic pole structure disposed on the yoke. The voice coil is connected to the vibration structure and is movable relative to the magnetic circuit structure. The yoke is connected to the shell through the bridging structure, and when the loudspeaker is in sound generating operation, the magnetic circuit structure is configured to vibrate independently relative to the shell under a separation of the bridging structure.

    摘要: An earphone, including: a housing, a first speaker unit, a second speaker unit. The housing has a sound output hole. The first speaker unit and the second speaker unit are separately independently fastened in the housing. The first speaker unit produces a sound toward the sound output hole. The second speaker unit is located on a side that is of the first speaker unit and that is away from the sound output hole and is spaced apart from the first speaker unit. A sound production frequency of the second speaker unit is smaller than a sound production frequency of the first speaker unit. A cavity is enclosed by the first speaker unit, the second speaker unit, and an inner wall of the housing, the cavity serves as a front cavity of the second speaker unit, and the front cavity communicates with the sound output hole through a sound output channel.

    摘要: A speaker device and an earphone include a housing, a coil iron support connected to the housing, a moving iron assembly, and a moving coil assembly. The moving iron assembly and the moving coil assembly are disposed on the coil iron support. A cavity is defined in the housing. A periphery of the coil iron support is embedded in the housing. The coil iron support includes a moving coil supporting portion and a moving iron supporting portion disposed on one side of the moving coil supporting portion. The moving iron assembly is partially disposed on the moving iron supporting portion. The moving coil assembly includes a voice diaphragm, a voice coil, a washer, and a magnet that are stacked in sequence. A periphery of the voice diaphragm is fixedly clamped with an inner side of the moving coil supporting portion.

    摘要: A detection unit has a fixed magnet, which is part of a magnetic circuit unit, and also has a movable magnet and a magnetic sensor, which are disposed below a cap. A fixed magnetic field component oriented toward a vibration direction acts on the magnetic sensor due to a leakage flux from the magnetic circuit unit. A movable magnetic field component acts from the movable magnet on the magnetic sensor in a direction crossing the fixed magnetic field component. A change in the angle of a detection magnetic field component, which is a combined vector formed from the magnetic field components in two directions, is detected by the magnetic sensor. According to the output in this detection, the operational position of the movable magnet is measured.
