发明名称 Loud-speaker simultaneous decompression- and phase-tuning device
摘要 An acoustic enclosure includes an electrodynamic speaker (H) with a magnetic circuit (T) cooled by a tunnel provided in the magnetic core (N). The tunnel diameter is optimised function of the speaker cone (C) decompression requirements relative to the pressure of the air circulating through the magnetic circuit. A plastic disc (M) is embedded in a cylindrical support (P) of a mobile coil (B) which is positioned in the centre of the cone. The sound is emitted by the front surface of the cone.
