Abstract
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.

A method of reducing sound leakage, the method comprising:
- providing a bone conduction speaker including:
- a vibration board;
- a transducer configured to cause the vibration board to vibrate;
- a housing connected to the transducer, the transducer causing the housing to vibrate, the vibration of the housing producing a leaked sound wave;
- and
- at least one sound guiding hole located on the housing and configured to guide a sound wave inside the housing through the at least one sound guiding hole to an outside of the housing, the guided sound wave interfacing with the leaked sound wave, the interfacing reducing 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 being lower than 4000 Hz.
