Description
[technical field]
The utility model relates to a kind of handset earphone, and what be specifically related to is a kind of improvement invention of external handset earphone.
[background technology]
Mobile phone is as a kind of communication tool, uses more and more universally, and present most of mobile phones support the mobile phone tails to insert the band ear-phone function, and earphone comprises headset earpiece and earphone microphone; During a lot of in the market mobile phone tails are inserted, all have voice output pin and phonetic entry pin basically and switch pin, described switching pin is that receiver or microphone that mobile phone carries are switched to external receiver or microphone; And during the tail of some mobile phone inserted, its voice output pin and switch pin and merged together was as long as find the voice output pin, just automatically switch, and its switching pin of some mobile phone and voice output pin still separate, so, to must also to find it to switch pin with external receiver.And for External micro phone, must find simultaneously and switch pin and phonetic entry pin, could realize the switching of External micro phone and built-in microphone.For at present, its external earphone all is to provide and deliver at random and the slotting external handset earphone that matches of mobile phone tail, but if these external handset earphones damage, will be difficult to find the external handset earphone of adaptive these mobile phones on the market, this is very inconvenient for most cellphone subscriber.
[utility model content]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of mobile phone tail of discerning to plug in receiver and microphone stitch, and signal is connected the external handset earphone that transmits.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish: a kind of external handset earphone, comprise the plug and the earphone that connect with lead, be provided with in the plug with the mobile phone tail and insert adaptive stitch, it is characterized in that, this external handset earphone has dial plate, dial plate be provided with pointer with the identical metal contact of described plug stitch quantity, each metal contact connects with corresponding described stitch respectively, described pointer is connected with earphone by lead, and stirring pointer can contact with each metal contact.
Particularly, a technical scheme of the present utility model is: described dial plate is provided with a pointer, and the metal contact is stirred center circumferential along pointer and arranged that pointer is connected with headset earpiece by lead.
Particularly, another technical scheme of the present utility model is: described dial plate is provided with two pointers, and described metal contact is stirred center circumferential along pointer and arranged that one of them pointer is by grounding through resistance, and another pointer is connected with headset earpiece by lead.
Particularly, another technical scheme of the present utility model is: described dial plate is provided with two pointers, and described metal contact is stirred center circumferential along pointer and arranged that one of them pointer is by grounding through resistance, and another pointer is connected with microphone by lead.
Particularly, last technical scheme of the present utility model is: described dial plate is provided with three pointers, described metal contact is stirred center circumferential along pointer and is arranged, one of them pointer is connected with headset earpiece by lead, another pointer is by grounding through resistance, and another pointer is connected with microphone by lead.
Adopt the external handset earphone of technique scheme, because the mobile phone tail contact pin pin that each metal contact is corresponding different, when pointer is stirred on the metal contact, just can pursue pin scanning by adversary's tail contact pin pin, in case phonetic entry pin or this voice output pin that contact mobile phone tail is inserted, mobile phone automatically switches to external earphone; Its switching is very convenient, has solved the inconvenient situation that can join after the cellphone subscriber damages with earphone everywhere, and it is very much convenient using.
