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 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.
