The leakage-of-the-sound inhibition method of a bone conduction speaker, and a bone conduction speaker

Japanese Patent JP6282749

B2

The present invention provides a method for suppressing sound leakage of a bone conduction loudspeaker and the bone conduction loudspeaker capable of suppressing sound leakage. The bone conduction loudspeaker comprises an opening-shaped casing, a vibrating panel and a transduction device. The transduction device is used for producing vibration and is accommodated in the casing. The vibrating panel is used for being attached to the skin and transmitting vibration. At least part of the casing is provided with at least one sound transmitting hole. The sound transmitting hole is used for transmitting a sound wave formed by air vibration in the casing out of the casing, and the sound wave interferes with a leakage sound wave to reduce amplitude of the leakage sound wave, wherein the casing vibrates and pushes the air outside the casing to form the leakage sound wave. In the present invention, by means of the sound wave interference principle, the amplitude is reduced so as to achieve the effect of reducing sound leakage. The solution has good sound leakage suppressing effect and is easy to achieve, the size and weight of the bone conduction loudspeaker are not increased, and product cost is also hardly increased.
