Abstract
An acoustic transducer including a diaphragm having an electrical conductor applied thereto such that at least one segment of the conductor is selectively separable from the diaphragm in response to electric power being applied to the conductor to thereby provide thermal stress relief to the diaphragm during use.
Claims20
In an acoustic transducer including;
- a frame,
- a diaphragm adhered to said frame and having an active area under tension spaced inside said frame,
- an electrical conductor means adhered to portions of a surface of said active area of said diaphragm, and
- at least one magnet means mounted so as to be spaced from said diaphragm;
- the improvement comprising:
- said electrical conductor means is formed as a conductor layer that is adhered with an adhesive layer onto said diaphragm, and
- at least one segment of said electrical conductor means being selectively separable from said portions of said diaphragm.

A planar magnetic transducer including;
- a frame,
- a diaphragm supported by said frame and having an active area under tension spaced inside of said frame,
- an electrical conductor layer applied by an adhesive layer so as to be adhered to portions of said active area of said diaphragm,
- at least one magnet means mounted so as to be spaced from said diaphragm;
- and
- at least one segment of said electrical conductor layer being separable from said portions of said active area of said diaphragm by at least one spacer means positioned between said at least one segment of said conductor layer and said portions of said active area of said diaphragm.
