Abstract: A switching circuit includes main switching a device and a drive circuit. The main switching device has a gate terminal, a drain terminal, and a first source terminal through which a main current flows, and a second source terminal for gate drive connected to drive circuit. The drive circuit has a bias capacitor having a negative electrode terminal connected to the second source terminal, a first series circuit formed between a positive electrode terminal and the gate terminal by connecting a high-side switch, a resistor, and a capacitor in series, and a second series circuit formed between the gate terminal and the second source terminal by connecting the capacitor, a resistor and a low-side switch in series. The drive circuit adjusts each of gate charge and discharge currents, and further damps the oscillation of the waveform of gate current/voltage.

Abstract: The present invention relates to a headphone including a housing defining a back chamber on a back side of a speaker unit. A headphone includes a speaker unit and a housing defining an internal space provided on an acoustic emission side as a back side of the housed speaker unit and an air chamber provided separately from the internal space. The housing includes a first housing member provided with a first hole allowing communication between an exterior and the air chamber, a second housing member attached to the speaker unit and coupled to the first housing member to define the internal space and the air chamber, and a third housing member fixed with the third housing member being sandwiched between the first and second housing members and provided with a second hole allowing communication between the air chamber and the internal space.

Abstract: A method of manufacturing a circuit substrate includes the steps of preparing a conductor paste in which a powder of at least one of a metal boride and a metal silicide is added to a powder of silver (Ag), applying the conductor paste to a surface of a ceramic substrate which has been fired, applying a glass paste to the surface of the ceramic substrate after applying the conductor paste, firing the conductor paste applied to the surface so as to form a conductor trace, and firing the glass paste applied to the surface so as to form a coating layer.

Abstract: A method of manufacturing a ceramic substrate includes the steps of preparing a ceramic paste in which a powder of at least one of a metal boride and a metal silicide is added to a raw material powder of a glass ceramic, applying the ceramic paste to a green sheet which is to become a ceramic layer after firing, applying a conductor paste which is to become a conductor trace after firing to the ceramic paste having been applied to the green sheet, and firing the green sheet carrying the ceramic paste and the conductor paste applied thereto.

Abstract: A ceramic substrate includes a ceramic layer mainly formed of a glass ceramic and a conductor trace mainly formed of silver (Ag). In an adjacent region located adjacent to the conductor trace, the concentration of boron atoms (B) contained in the ceramic layer increases toward the conductor trace.

Abstract: A method for manufacturing a ceramic substrate containing glass includes a firing step in which an unfired silver-based conductor material is disposed on an unfired ceramic layer and is fired. The unfired silver-based conductor material contains at least one of a metal boride and a metal silicide.

Abstract: An example vibrating body for the acoustic transducer may include a diaphragm including a first vibrating part and a second vibrating part located at an outer circumference of the first vibrating part. A coil is configured to vibrate the diaphragm. An edge portion is located at an outer circumference of the diaphragm. A plurality of ribs are provided outside of the coil on the second vibrating part formed integrally with the second vibrating part. A plurality of ribs is provided on the edge portion formed integrally with the edge portion. None of the integrally formed ribs is provided inside of the coil on the first vibrating part. The ribs provided on the second vibrating part are formed in an inner circumferential side of regions of the edge portion, the regions being located between the ribs provided on the edge portion next to each other.
