Abstract
A headset includes a speaker, such as a side firing dipole speaker. The headset includes a front chamber that receives sound waves from a first side of the speaker and a rear chamber that receives sound waves from a second side of the speaker. A control leak channel connects the front chamber and the rear chamber. An acoustic mesh may be located within the control leak channel. The speaker configuration is configured to reduce total harmonic distortion of the speaker, particularly in ranges such as 3-6 kHz, while maintaining the broadband efficiency of the speaker.
Claims17
A headset comprising:
- a dipole speaker located within a temple section of the headset, the temple section of the headset comprising:
- a front chamber,
- a rear chamber, and
- a control leak channel connecting the front chamber to the rear chamber and oriented perpendicular to a direction of movement of a membrane of the dipole speaker.
An audio system comprising:
- a side firing dipole speaker;
- a front chamber configured to receive first sound waves from a first side of the side firing dipole speaker;
- a rear chamber configured to receive second sound waves from a second side of the side firing dipole speaker;
- and
- a control leak channel connecting the front chamber to the rear chamber and oriented perpendicular to a direction of movement of a membrane of the side firing dipole speaker.
An artificial reality headset comprising:
- a speaker located within a portion of the artificial reality headset;
- a first chamber configured to receive first sound waves from the speaker;
- a second chamber configured to receive second sound waves from the speaker;
- and
- a control leak channel connecting the first chamber to the second chamber and oriented perpendicular to a direction of movement of a membrane of the speaker.
