    摘要： A diaphragm is provided that has small mechanical anisotropy even when heat is applied to the diaphragm in the production process. The diaphragm includes a biaxially stretched film stretched in a first direction (the machine direction) and a second direction (the transverse direction), wherein the entire surface of the biaxially stretched film has a first pattern and a second pattern, the first pattern has ridges and grooves with a first pitch, the second pattern has ridges and grooves with a second pitch, the second pitch is smaller than the first pitch, the second pattern is formed along the first direction or the second direction, and the length of regions defined by the first pattern in the first direction differs from the length of the regions in the second direction.

    摘要： A microphone includes a tubular microphone case having conductivity, a circuit board on which a circuit is configured, the circuit being used for an operation of a microphone unit that converts an audio signal into an electrical signal, a light source that is accommodated in a position close to a first end of the microphone case and emits light, a light source mounting board on which the light source is placed, a holding member that has conductivity, holds the light source mounting board and the circuit board, and is fixed to the microphone case, and a light guide member including a protrusion. The holding member includes a light source mounting board accommodating portion that accommodates the light source mounting board, a circuit board accommodating portion that accommodates the circuit board, and a hole that can accept the protrusion.

    摘要： A noise-cancelling headphone is provided that avoids an influence of the wind and prevents degradation in the sound quality of the reproduced sound output from a driver unit. The noise-cancelling headphone includes an ear piece including a housing unit having an interior and an exterior, a driver unit attached to the housing unit, and a microphone collecting external sounds at the exterior of the housing unit. The housing unit includes an accommodating portion accommodating the microphone and a sound collecting hole establishing the communication between the accommodating portion and the exterior of the housing unit. The accommodating portion is disposed in an upper portion of the housing unit of the noise-cancelling headphone when worn by the user. The sound collecting hole is open toward the upper side of the housing unit of the noise-cancelling headphone when worn by the user.

    摘要： A microphone device includes a microphone unit that outputs an electrical signal upon receipt of a sound wave, a microphone case that supports the microphone unit in its inside with cushioning members formed of an elastic material (rubber material), and a microphone cable that supplies the electrical signal from the microphone unit to an output connector attached to the microphone case. A part of the microphone cable is attached in a state of meandering back and forth once or more between one surface and the other surface of the rear cushioning member formed in a flat manner. This configuration allows to suppress transmission of vibration through the microphone cable connected to the microphone unit and prevent generation of vibration noise due to free vibration of the microphone cable.

    摘要： A boundary microphone is provided that does not generate spark discharge during an operation of a switch. The boundary microphone includes a microphone unit 6, and a switching unit (a button 4, a tube 9, a detector 10, a comparator, and a switching circuit) that switches turning-on or turning-off of output signals from the microphone unit 6, wherein the switching unit (the button 4, the tube 9, the detector 10, the comparator, and the switching circuit) includes an air chamber 9 and a controller that controls the turning-on or turning-off based on the air pressure inside the air chamber 9.
