Abstract

Claims (23)

1 . A speaker, comprising:

a housing having a first sidewall and a second sidewall connected to the first sidewall;

a transducer residing inside the housing and configured to generate vibrations; and

a first sound guiding hole located on the first sidewall, the first sound guiding hole being configured to guide a first sound wave generated by the vibrations of the transducer to an outside of the housing; and

a second sound guiding hole located on the second sidewall, the second sound guiding hole being configured to guide a second sound wave generated by the vibrations of the transducer to the outside of the housing, the guided first sound wave interfering with the guided second sound wave in a target region, and the interference reducing a sound pressure level of a leaked sound wave of the speaker in the target region.

2 . The speaker of claim 1 , wherein the first sidewall of the housing is configured to face towards a face of a user.

3 . The speaker of claim 2 , wherein the first sidewall of the housing has a silicone rubber configured to contact an interior of the user's auricle.

4 . The speaker of claim 1 , wherein the first sound guiding hole is located on a lower portion of the first sidewall, the lower portion of the first sidewall ranges from ⅔ height of the first sidewall to the second sidewall.

5 . The speaker of claim 1 , wherein the guided first sound wave and the guided second sound wave have different phases.

6 . The speaker of claim 1 , wherein the guided first sound wave and the guided second sound wave have substantially same amplitude.

7 . The speaker of claim 1 , wherein the first sound guiding hole includes a damping layer.

8 . The speaker of claim 7 , wherein the damping layer includes at least one of: a tuning paper, a tuning cotton, a nonwoven fabric, a silk, a cotton, a sponge, or a rubber.

9 . The speaker of claim 1 , wherein a shape of the first sound guiding hole includes circle, ellipse, quadrangle, rectangle, or linear.

10 . The speaker of claim 1 , further comprising:

an acoustic route coupled to the second sound guiding hole, wherein the second sound wave is propagated to the second sound guiding hole along the acoustic route, and the acoustic route is configured to adjust a frequency of the guided second sound wave.

11 . The speaker of claim 10 , wherein the acoustic route is configured to adjust a frequency of the guided second sound wave by filtering sound waves in target frequencies.

12 . The speaker of claim 10 , wherein the acoustic route includes one or more lumen structures.

13 . The speaker of claim 10 , wherein the acoustic route includes one or more resonance cavities.

14 . The speaker of claim 1 , wherein at least a portion of the leaked sound wave whose sound pressure level is reduced is within a range of 1500 Hz to 3000 Hz.

15 . The speaker of claim 14 , wherein the sound pressure level of the at least a portion of the leaked sound wave is reduced by more than 10 dB on average.

16 . The speaker of claim 1 , wherein at least a portion of the leaked sound wave whose sound pressure level is reduced is within a range of 2000 Hz to 2500 Hz.

17 . The speaker of claim 16 , wherein the sound pressure level of the at least a portion of the leaked sound wave is reduced by more than 20 dB on average.

18 . The speaker of claim 1 , wherein a third sound guiding hole is located on the first sidewall.
