Abstract
A loudspeaker assembly for on-ear headphones, to be arranged on and/or over the ear, includes a housing in which a woofer is arranged and configured to emit low frequency sound waves along a low frequency sound beam axis toward the wearer's the ear. At least one tweeter is arranged in the housing and configured to emit high frequency sound waves along a high frequency sound beam axis toward the wearer's the ear. The at least one tweeter is a MEMS loudspeaker.
Claims18
A loudspeaker assembly for on-ear headphones, to be arranged on and/or over an ear of the user, the loudspeaker assembly comprising:
- a housing;
- a woofer disposed in the housing and configured to emit low frequency sound waves along a low frequency sound beam axis toward the ear;
- and
- a plurality of tweeters disposed in the housing, each of the plurality of tweeters being configured to emit high frequency sound waves along a respective high frequency sound beam axis;
- and
- wherein each of the plurality of tweeters is a MEMS loudspeaker and is arranged radially spaced apart from the low frequency sound axis;
- wherein each of the plurality of tweeters is arranged circumferentially around the woofer and the low frequency sound beam axis;
- and
- wherein the housing is configured so that when the loudspeaker assembly is in use as intended on or over an ear of the user, a first number of the plurality of tweeters is arranged in front of the ear and a second number of the plurality of tweeters is arranged behind the ear such that the first number exceeds the second number.
Headphones to be arranged on and/or over an ear of the user, the headphones comprising:
- a loudspeaker assembly that includes a housing, a woofer disposed in the housing and configured to emit low frequency sound waves along a low frequency sound beam axis toward the ear, and
- a plurality of tweeters disposed in the housing, each of the plurality of tweeters being configured to emit high frequency sound waves along a respective high frequency sound beam axis, wherein each of the plurality of tweeters is a MEMS loudspeaker and is arranged radially spaced apart from the low frequency sound axis;
- wherein each of the plurality of tweeters is arranged circumferentially around the woofer and the low frequency sound beam axis;
- and
- wherein the housing is configured so that when the loudspeaker assembly is in use as intended on or over an ear of the user, a first number of the plurality of tweeters is arranged in front of the ear and a second number of the plurality of tweeters is arranged behind the ear such that the first number exceeds the second number.
