发明名称 Voice coil support for loudspeaker
摘要 According to the state of the art, the voice coil (12) of a loudspeaker is connected to the voice coil support (10) in such a way, that first the coil wire, which is surrounded by a self-bonding material, is wound around the outside jacket (14) of the voice coil support (10), and then is baked. However, under mechanical load, such a connection is only temperature-stable to about 200 degrees Celsius. It is therefore the task of the invention to present a connection between voice coil (12) and voice coil support (10), which is also temperature-stable above 200 degrees Celsius. This task is fulfilled by the invention, in that holding elements (13) are placed around the outside jacket of the voice coil (12), which act against any radial and/or axial change in position of the individual winding wires of voice coil (12). These holding elements (13) can be (ultrasonically) welded to the voice coil support (10), or be attached to the inside sleeve (18) of the voice coil support (10) by simple bending.
