A speaker diaphragm includes an edge formed from an elastomer, and a diaphragm body that is to be joined to the edge. A joint between the edge and the diaphragm body includes a melting portion between the edge and the diaphragm body.

The present application provides a method of manufacturing a resonant panel (200) of a flat panel loudspeaker. The method comprises: pressing a resonant panel blank between a first pressing surface (302) and a second pressing surface of a press, whereby to form the resonant panel (200) of the flat panel loudspeaker. The second pressing surface substantially opposes the first pressing surface (302). The first pressing surface (302) comprises at least one tool relief region (306, 312, 314, 316, 318), whereby to form at least one corresponding respective panel relief region (206, 212, 214, 216, 218) in a surface of the resonant panel (200).

An outer structure of a magnetic circuit is held inside a holder recess of a magnetic circuit holder of a frame. A pressing portion is screw-fixed to a mounting surface of the magnetic circuit holder. Elastically deformable pressing arms are formed at the pressing portion, and the pressing arms press a restriction surface of the outer structure of the magnetic circuit.

A substantially full-range loudspeaker system for acoustic sound reinforcement can include a woofer section with a first loudspeaker driver configured to reproduce audio signals in a first frequency range and a controlled-directivity horn section configured to reproduce other audio signals in a different second frequency range. In an example, the horn section includes a second loudspeaker driver comprising a cone-diaphragm transducer and a dust dome, an acoustic lens having a first side and an opposite second side, wherein the first side of the lens is coupled to a sound-projecting face of the second loudspeaker driver, and a waveguide coupled to the second side of the lens, wherein the waveguide comprises walls that follow arcuate paths in horizontal and vertical planes.

This disclosure relates to speakers and more specifically to an array speaker for distributing music uniformly across a room. A number of audio drivers can be radially distributed within a speaker housing so that an output of the drivers is distributed evenly throughout the room. In some embodiments, the exit geometry of the audio drivers can be configured to bounce off a surface supporting the array speaker to improve the distribution of music throughout the room. The array speaker can include a number of vibration isolation elements distributed within a housing of the array speaker. The vibration isolation elements can be configured reduce the strength of forces generated by a subwoofer of the array speaker.
