FIELD: acoustics.
SUBSTANCE: invention relates to acoustics, particularly to loudspeakers. Acoustic loudspeaker consists of following main parts: magnet, basket, voice coil, centring washer (spider), supply conductors, diffuser (cone), dustproof cap, suspension (surround), lower and upper magnetic conductors. Loudspeaker basket has a stepped shape which increases the diffuser area.
EFFECT: technical result is an increase in the useful area of the diffuser, which enables the acoustic loudspeaker to emit a wider range of audio frequencies.
