Abstract

The invention relates to an electroacoustic transducer (1), which comprises: a ring-shaped magnetic assembly (3) for generating a magnetic field, an elastic suspension (4) connected with the magnetic assembly, and an elastic suspension (4) connected with the elastic suspension A support (8) attached to and supporting a coil (6) adapted to move in the magnetic field generated by the magnetic assembly, and a sound membrane ( 5). The magnetic assembly (3) comprises: a thin housing support structure (7) made of non-magnetic material, and a plurality of magnets (30) with a magnetic axis (A) and an axial anisotropy, said magnets ( 30) Arranged side by side in said thin housing support structure (7) which acts as a pressure bearing structure for the transducer and as a housing structure for the magnets.

Description

technical field [0001] The present invention relates to an electromechanical-electroacoustic transducer with low thickness and high stroke, especially for loudspeakers and its manufacturing method. Background technique [0002] US Patent No. 6359997 discloses a loudspeaker comprising a magnetic ring consisting of a plurality of radially magnetized magnets arranged in a laterally adjacent manner. Radial magnetization means that the lines of magnetic induction converge radially to a point, which is the center of the transducer, so the magnetic ring is only suitable for circular transducers. [0003] Furthermore, the magnetic ring is supported by a mandrel mounted in the transducer basket, so the magnetic ring is not a self-supporting element. The above-mentioned transducer has an elastic suspension connecting the moving coil to the basket. However, the provision of a spindle supporting the magnetic assembly and the presence of a suspension does not allow for a particularly t...
