A microphone unit () is provided with an electro-acoustic transducer () which converts acoustic signals into electric signals on the basis of the oscillation of a diaphragm (), and a housing () which contains the electro-acoustic transducer (). The housing () is provided with: a first sound conduction space (SP) that guides sound waves from the outside to one side of the diaphragm () via at least one first aperture () formed on the exterior of the housing (); and a second sound conduction space (SP) that guides sound waves from the outside to the other side of the diaphragm () via at least one second aperture () formed on the exterior of the housing (). The total square area of at least one first aperture () and the total square area of at least one second aperture () are not the same.

Microphone unit

A microphone unit () comprises a first vibrating part (), a second vibrating part (), and a housing () for accommodating the first vibrating part () and the second vibrating part (), the housing being provided with a first sound hole (), a second sound hole (), and a third sound hole (). The housing () is provided with a first sound path () for transmitting sound pressure inputted from the first sound hole () to one surface () of a first diaphragm () and to one surface () of a second diaphragm (), a second sound path () for transmitting sound pressure inputted from the second sound hole () to the other surface () of the first diaphragm (), and a third sound path () for transmitting sound pressure inputted from the third sound hole () to the other surface () of the second diaphragm ().

Microphone unit and voice input device comprising same

A microphone unit () comprises a first vibrating part (), a second vibrating part (), and a case () for accommodating the first vibrating part () and the second vibrating part (), the case being provided with a first sound hole () and a second sound hole (). The case () is provided with a first sound channel () for transmitting acoustic pressure inputted from the first sound hole () to one surface () of a first diaphragm () and to one surface () of a second diaphragm (), a second sound channel () for transmitting acoustic pressure inputted from the second sound hole () to the other surface () of the second diaphragm (), and a sealed space (S) that faces the other surface () of the first diaphragm ().

A code indicating the encoding format classification is recorded in a multi remote control transmitter attached to a video apparatus . The code is transmitted at every interval T successively. Also, at every transmission of code, an instruction of power on is transmitted in a format corresponding to the code. When the code conforming to the peripheral equipments connected to the video apparatus is transmitted, the video apparatus is activated to input a video signal from the video apparatus to the multi remote control transmitter . The conformable code, together with the data for explaining a preset method of the multi remote control transmitter , is output in terms of the video signal to the peripheral equipments, and displayed.
