摘要:
An adapter (3, 3′, 3″) for a loudspeaker (2) is disclosed, wherein the loudspeaker (2) is provided to be used in free space. The adapter (3) comprises means to provide an acoustic impedance on the backside (b) of the loudspeaker (2) in such a way, that an adaptation of the loudspeaker function from a free-space operation mode to an on-the-car or in-the-car operation mode is achieved.
摘要:
A speaker and method for making the same are provided. The speaker includes a permanent magnet and a coil disposed about a first axis around the permanent magnet, the coil being configured to move along the first axis. The speaker further includes a membrane attached to a top surface of the coil and a stabilizer contacting at least one of an internal surface, an external surface, and a bottom surface of the coil, and configured to limit movement of the coil relative to a second axis perpendicular to the first axis.
