[0013] The invention adopts the structure of double-layer sound outlet holes with large outside and small inside; double-layer dust-proof net with sparse outside and inner-dense; It not only prevents iron filings from entering the receiver, but also prevents dust and other debris from blocking the receiver hole, and can meet the requirements of the receiver's acoustic structure and greatly reduce the failure of the receiver.
[0014] Double-layer sound holes with large outside and small inside: the outer sound hole has a large area and is not easy to be blocked by debris; the inner sound hole has a small area, and it is not easy for iron filings to enter.
[0015] Double-layer dust-proof net structure with sparse outer and inner dense: the outer dust-proof net is relatively sparse and not easy to be blocked by debris; the inner dust-proof net is fine, even if the iron filings pass through the first layer, it cannot pass through the first layer. Two-layer dust net.
