Speaker chassis for use in compact one-way or two-way loudspeaker systems, has band-shaped profile tightly bonded to membrane area along flow channel, where total area of band-shaped profile is seventy percentage of membrane area of chassis

摘要

The chassis has a band-shaped profile (BP) provided with walls that are connected in parallel to an oscillation axis of a membrane (M). An edge of the band-shaped profile is located on a front part of the membrane. The band-shaped profile is tightly bonded to a membrane area (SD) along a U-flow channel (SK). The membrane is provided with a rigid unit. Length (L) of the band-shaped profile corresponds to dual equivalent membrane perimeter of the chassis, where total area (F) of the band-shaped profile is 70% of the membrane area of the chassis. The membrane and the band-shaped profile are made of light paper and prolonged fibrous material.
