Latest Patents

Horie's latest patents include a microphone output transmission circuit and a multiple magnetoresistance element. The microphone output transmission circuit is designed for capacitive microphones, such as electret microphones. It employs a differential amplifier to provide a transformerless balanced connection to a microphone transmission line. Power is applied through a phantom connection, superimposing a DC voltage on two balanced signal conductors. This innovative design allows for a bidirectional characteristic when connecting a pair of microphones with oppositely-directed sound-gathering planes.

The multiple magnetoresistance element consists of a first stripe group and a second stripe group, which are made of ferromagnetic material. These stripes are electrically connected in series and spaced apart by a predetermined distance. The design allows for multiple main current path portions, enhancing the functionality of the element.
