ELECTRODYNAMIC LOUDSPEAKER WITH EASILY REMOVABLE MODULE OF MOVING PART Russian patent published in 2022 - IPC H04R9/04 

FIELD: acoustics.

SUBSTANCE: invention relates to electroacoustics, namely to electrodynamic loudspeakers. Electrodynamic loudspeaker is made of detachable and bearing frame. Magnetic system is attached to the bearing frame; the system comprises a lower magnetic conductor with a core, a permanent magnet and an upper magnetic conductor. Suspension and a centring washer are attached to the detachable frame, which are attached to a diffuser, a cap and a voice coil, which by its winding is in the magnetic gap and interacts with the magnetic field of the magnetic system, and the upper part of the voice coil is rigidly connected to the diffuser and the centring washer. Flexible conductors connect the voice coil to terminals located on the detachable frame to supply an electric signal to the voice coil. Detachable frame together with diffuser, suspension, centring washer, voice coil, cap, flexible wires and terminals is detachable module and is attached to lower frame and/or magnetic system by detachable connections and is configured to be centred relative to the magnetic system by interaction of the centring surface on the detachable frame relative to the centring surface of the magnetic system.

EFFECT: reduced time for repair of the device and its simplification, possibility to quickly change sound characteristics of the device, as well as implementation of accurate and fast alignment of the movable part relative to the magnetic system.
