摘要:
An ear cup for a hearing protector includes a cup-shaped outer casing, a sealing ring on a rim of the outer casing, and at least one electrical component such as a microphone. The electrical component is mounted on a flexible circuit board attached on the outer surface of the outer casing, where the outer casing includes a slit through which the flexible circuit board extends to the inside of the outer casing so as to provide electrical connections between the electrical component and an electrical circuitry inside the outer casing. Thus, there is no need for wide openings on the outer casing of the ear cup, instead only a narrow slit suffices. This facilitates achieving good noise reduction properties.
