Abstract
An improved driver assembly for a panel loudspeaker includes a retaining element for locating the voice coil with respect to the magnet assembly and forming a surface for removable attachment of the driving assembly to a radiating member. In a preferred embodiment, the retaining element is injection moulded from a hydrogel material with Shore A hardness in the range 0 to 20.
Claims30
A driver assembly for a panel loudspeaker, the driver assembly comprising a voice coil, a magnet assembly, a substantially rigid planar member, and a retaining element for retaining the magnet assembly with respect to the voice coil, wherein the retaining element defines a first surface adapted to be removably coupled to a panel forming an acoustic radiator, and the substantially rigid planar member is attached to the voice coil and is disposed between the voice coil and said first surface.
A driver assembly for a panel loudspeaker, the driver assembly comprising a voice coil, a magnet assembly, and a moulded retaining element for retaining the magnet assembly with respect to the voice coil, wherein the moulded retaining element defines a first surface adapted to be coupled to panel forming an acoustic radiator.
A retaining element for a panel loudspeaker driver assembly, the retaining element comprising a disc defining a first surface adapted to be removably coupled to an acoustic radiator, and a wall upstanding from an opposing surface of the disc, wherein the wall is adapted to accommodate a voice coil and a magnet assembly in a spatially separated relationship.
A method of mounting an acoustic radiator of a panel loudspeaker comprising the steps of:
- locating a voice coil and a magnet assembly in a moulded retaining element, and;
- removably attaching a surface defined by the moulded retaining element to a panel forming the acoustic radiator.
A method of manufacturing a driving assembly for a panel loudspeaker, the method comprising the steps of:
- forming a retaining member by injection moulding, and;
- assembling a voice coil and magnet assembly in the retaining member.
