Sound barrier containing microphone for musical wind instrument - comprises sealed sound-proof enclosure clipped to instrument horn and containing amplifier microphone

摘要

A sealed enclosure (1) with parallel sides is extended by a trapezoidal profile closed at its end (3). The lower face has an oblique section (4) extended by a rectilinear area (5). The enclosure walls are made of a rigid sound proof material reinforced by an inner wall (7) coated with sound proof material (8) to provide a damping or reflecting effect. Clips permit attachment of this assembly to the instrument. A sealing ring provides sealing for sound proofing. The internal chamber contains a deflector (9) to direct the sound without vibration to a microphone (11). This transmits the sound to the musician's headset through a hifi amplifier. A switch enables a listener to communicate with the musician through a separate microphone connected to the amplifier.
