Further, the distance between the front of loudspeaker and the front of described face-piece is 13mm ~ 15mm.
Further, above-mentioned aluminium sheet is provided with a flared channels, and described wiring board is provided with a through hole, and described loudspeaker are arranged in flared channels, and the wiring board at the front of loudspeaker and through hole edge is inconsistent.
Further, this intercom also comprises a horn chamber cover plate, and one end and the face-piece of this horn chamber cover plate are inconsistent, the other end and wiring board inconsistent, and the middle part of horn chamber cover plate is provided with the hollow out position of matching with through hole.
Particularly, above-mentioned horn chamber cover plate is horn-like, one end of this horn chamber cover plate is provided with terminal pad, the other end is provided with annular protrusion, above-mentioned face-piece back is provided with mounting groove, terminal pad is removable installed in mounting groove, and the wiring board at annular protrusion and through hole edge is inconsistent, and above-mentioned mounting groove bottom surface is provided with described bellmouth orifice.
Further, a seal washer is also provided with between above-mentioned annular protrusion and above-mentioned wiring board.
Particularly, above-mentioned seal washer is provided with an annular groove suitable with above-mentioned annular protrusion.
According to the arbitrary described a kind of intercom of claim 4-6, it is characterized in that: between described horn chamber cover plate and face-piece, be also provided with an Air Filter.
From the above-mentioned description to the utility model structure, the utility model tool has the following advantages:
In one, the utility model, the distance between the front of loudspeaker and the front of face-piece is not less than 12.9mm, makes to maintain a segment distance between loudspeaker and bellmouth orifice.According to object away from the more weak principle of magnet suffered magnetic far away, when the suffered magnetic force such as the iron filings of intercom outside or charged dust are weak to time to a certain degree, namely iron filings or charged dust and other impurities cannot be inhaled into intercom inside.Through lot of experiments and the capacity issue taking intercom into consideration, it is the most suitable that the distance between the front of loudspeaker and the front of face-piece gets 13mm ~ 15mm.
Two, in the utility model, wiring board is provided with a through hole, and this through hole side is provided with the horn chamber cover plate for keeping the distance between loudspeaker and face-piece, and opposite side is provided with loudspeaker.Bellmouth orifice, horn chamber cover plate, through hole and loudspeaker form a sounding passage, ensure the voice effect of intercom, and are convenient to disassembly, cleaning; Also can prevent dust and other impurities from entering other spaces of intercom inside by bellmouth orifice simultaneously, ensure the useful life of intercom.At bellmouth orifice, place is also provided with Air Filter, enters intercom inside for hindering other foreign material such as dust further.
