摘要： A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

摘要： A bone conduction speaker includes a housing, a vibration board and a transducer. The transducer is located in the housing, and the vibration board is configured to contact with skin and pass vibration. At least one sound guiding hole is set on at least one portion of the housing to guide sound wave inside the housing to the outside of the housing. The guided sound wave interfaces with the leaked sound wave, and the interfacing reduces a sound pressure level of at least a portion of the leaked sound wave. A frequency of the at least a portion of the leaked sound wave is lower than 4000 Hz.

摘要： A shock wave generating unit includes a housing and a disk in the housing. The disk includes a vibration plate, which corresponds to a shock wave transmission member covering a first opening of the housing and includes an insulating thin elastic plate and a thin metal plate. The insulating thin elastic plate, with one side corresponding to the shock wave transmission member and the opposite side provided with the thin metal plate, has a hollow portion for partially exposing the thin metal plate and forms an accommodating cavity together with the exposed portion of the thin metal plate and the shock wave transmission member. A shock wave transmission medium can circulate through the accommodating cavity via a channel in the housing and is in contact with the exposed portion of the thin metal plate to facilitate dissipation of the heat generated by the disk during operation.
