Abstract
The invention relates to a portable electronic device, comprising: at least two directional microphones for stereo sound pickup, each one of the two directional microphones defining a direct sound direction and an opposite sound direction towards which the directional microphones are directed; and a housing comprising for each of the directional microphones a first hole and a second hole, the first hole being located at a different side of the portable electronic device than the second hole.
Claims23
A portable electronic device, comprising:
- at least two directional microphones for stereo sound pickup, each one of the two directional microphones defining a direct sound direction and an opposite sound direction towards which the directional microphones are directed;
- and
- a housing comprising for each of the directional microphones a first hole and a second hole, the first hole being located at a different side of the housing of the portable electronic device than the second hole;
- wherein the direct sound direction of each microphone is oriented towards the first hole and the opposite sound direction of each microphone is oriented towards the second hole;
- wherein the housing is configured for housing the portable electronic device and is formed as a plate defined by two main areas framed by a top side, a bottom side and a first and a second lateral side, wherein the two main areas define a front side and a back side of the housing;
- and
- wherein the first hole for a first directional microphone is located in the first lateral side, the first hole for a second directional microphone is located in the second lateral side and the second holes for the first and second microphones are located in the bottom side or in the top side of the housing such that directivity polar patterns of the two directional microphones are directed towards the lateral sides of the housing.
