    Abstract: The present disclosure relates to a speaker device including a circuit housing, an ear hook, a rear hook, and a speaker assembly. The speaker assembly may include a headphone core and a housing for accommodating the headphone core, the housing may include a housing panel facing a human body and a housing back opposite to the housing panel, and the headphone core may cause the housing panel and the housing back to vibrate. An absolute value of a difference between a first phase of a vibration of the housing panel and a second phase of a vibration of the housing back may be less than 60 degrees when a frequency of each of the vibration of the housing panel and the vibration of the housing back is between 2000 Hz and 3000 Hz.

    Abstract: The embodiments of the present disclosure may disclose a vibration sensor, including: an acoustic transducer and a vibration assembly connected with the acoustic transducer. The vibration assembly may be configured to transmit an external vibration signal to the acoustic transducer to generate an electric signal, the vibration assembly includes one or more groups of vibration diaphragms and mass blocks, and the mass blocks may be physically connected with the vibration diaphragms. The vibration assembly may be configured to make a sensitivity degree of the vibration sensor greater than a sensitivity degree of the acoustic transducer in one or more target frequency bands.
