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 wave and the leaked sound wave form interference so that the amplitude of the leaked sound wave is reduced.
Claims20
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 having a phase different from a phase of the leaked sound wave in a target region, the guided sound wave changing an amplitude of the leaked sound wave in the target region.
