Abstract
Resistive film insulating trip is plated the present invention relates to a kind of mechanical horn phenolic aldehyde laminate layer cotton cloth plate.Hard contact mechano-electronic loudspeaker can produce larger electric arc in atmosphere due to the break-make of hard contact when working, and the presence of such a electric arc influences whether the electric conductivity of hard contact, reduce its work reliability it is serious when can cause the loudspeaker can not normal work.Present invention composition includes：Carbon oil resistive film（1）, insulating trip（3）Carry out via and cover copper（2）Processing, applies carbon oil resistive film（1）Realize that two sides is electrically connected, quite in an insulating trip two ends resistance in parallel, play a part of reducing arcing in the loudspeaker course of work.The present invention is applied to mechanical horn.
Description
Technical field：
It is used for hard contact mechano-electronic loudspeaker the present invention relates to one kind；It is specifically related to a kind of to be used to eliminate hard contact two

Think enter, bring significant technological progress.
Brief description of the drawings：
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the circuit diagram of the present invention.
In figure：1 is carbon oil resistive film, and 2 be via, and 3 be phenolic aldehyde laminate layer cotton cloth plate, and 4 be hard contact, and 5 be resistance, and 6 are
Power supply, 7 be ground connection.
Embodiment：
Embodiment 1：
Mechanical horn plates the insulating trip of resistive film, and its composition includes：Carbon oil resistance:1, insulating trip 3 carries out via 2 and covered at copper
Reason, applies carbon oil resistive film and realizes that two sides is electrically connected, and a suitable insulating trip two ends resistance 5 in parallel plays reduction loudspeaker work
During arcing effect.
Embodiment 2：
Mechanical horn insulating trip plating resistive film according to embodiment 1, it is in parallel at mechanical electric horn hard contact two ends
One resistance, shares current value when part metals contact 4 disconnects, and plays and reduces contact arc discharge, reduces hard contact ablation
Effect, to improve the service life of mechano-electronic loudspeaker.
Embodiment 3：
Mechanical horn insulating trip plating resistive film according to embodiment 1, integrates insulating trip and extinguishing arc resistance, most
The simplification technique of limits and reduce cost.
