Abstract
The utility model relates to an incoming flash lamp receiver for a mobile telephone, which comprises a main body 1, loudspeaker covers 2, loudspeakers 3, receiver lines 4, a plug 5 of the mobile phone and a microphone 6. The utility model is characterized in that a circuit board 7 which is arranged in the main body 1 of the receiver is provided with an incoming flash lamp circuit 8. The incoming flash lamp circuit is composed of a flash integrated circuit chip IC, a peripheral circuit of the flash integrated circuit chip IC, and light emitting diodes D2, D3 which are connect with the output terminal of the IC. When a call comes to the mobile telephone call, the incoming flash lamp circuit operates, and the lightening and the chromatic flashing are carried out by the light emitting diodes.
Description
The utility model relates to the earphone that a kind of mobile phone is used, and particularly relates to a kind of mobile phone incoming call flashing light earphone that can carry out the flashing light prompting when mobile phone is sent a telegram here.
As everyone knows, mobile phone has its obvious superiority as a kind of new communication tool instrument, thereby is just used by increasing people with the growth rate that is exceedingly fast.Yet many people know that also because the transmitting power of mobile phone is bigger, its electromagnetic intensity of launching is also bigger, and strong electromagenetic wave radiation can produce adverse influence to human body.Just be based on this reason, a lot of people have brought into use the mobile phone earphone special to answer and converse, but the existing mobile phone earphone can only converse, and function is comparatively single.
The purpose of this utility model is to provide a kind of and can not only answers and converse, and is attended by colour flash when incoming call and conversation, novel interesting mobile phone incoming call flashing light earphone.
For achieving the above object, the utility model provides a kind of mobile phone incoming call flashing light earphone, this earphone comprises fuselage 1, speaker cover 2, loud speaker 3, earphone cord 4, mobile phone plug 5 and microphone 6, it is characterized in that, the wiring board 7 in the earphone fuselage 1 is provided with incoming call flashing circuit for lamp 8.
Described incoming call flashing circuit for lamp 8 is made of flash of light integrated circuit die I C and peripheral circuit thereof and the light-emitting diode D2, the D3 that are connected to the IC output.
The peripheral circuit of flash of light integrated circuit die I C comprises the detector diode D1, the coupling capacitance C1 that are serially connected with circuit input end, signal amplifying triode Q1, and biasing resistor R1, R2 and partially installing capacitor C2.
Described fuselage 1 is formed by connecting by loam cake 11 and lower cover 12.
As seen from the above technical solution, the utility model is owing to be provided with the incoming call flashing circuit for lamp in earphone, thereby when mobile phone is sent a telegram here, the work of incoming call flashing circuit for lamp, send colour flash by light-emitting diode, make incoming call that auditory tone cues not only be arranged, and be attended by the colour flash prompting, therefore make the mobile phone earphone more perfect function, more be suitable for by the user and liked.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structure cutaway view.
Fig. 2 is the utility model circuit theory diagrams.
Mobile phone incoming call flashing light earphone of the present utility model mainly is made of earphone portion and the incoming call flashing circuit for lamp that is contained in the earphone.Wherein the earphone portion structure as shown in Figure 1, it comprises fuselage 1, speaker cover 2, loud speaker 3, earphone cord 4, mobile phone plug 5 and microphone 6, above-mentioned fuselage 1 comprises loam cake 11 and lower cover 12, inboard at loam cake is provided with joint pin 111 in the proximal edge place up and down, the inboard of lower cover then is provided with and the corresponding connecting hole 121 of this joint pin, the joint pin of loam cake is inserted in the connecting hole of lower cover and makes both form socket connection.In fuselage, loud speaker 3 is housed by upper end, the outer fuselage end of loud speaker is socketed with speaker cover 2, earphone cord 4 is introduced in the fuselage by the loam cake middle part, and links to each other with microphone 6 with loud speaker respectively, and the earphone cord other end links to each other with mobile phone by mobile phone plug 5.
Main points of the present utility model are to be provided with an incoming call flashing circuit for lamp 8 in the earphone fuselage, this circuit structure as shown in Figure 2, it is made of flash of light integrated circuit die I C and peripheral circuit thereof and the light-emitting diode D2, the D3 that are connected to the IC output.The integrated circuit die I C that wherein glistens selects the special-purpose flash of light of A5403-05 chip for use, and its peripheral circuit then comprises detector diode D1, coupling capacitance C1, signal amplifying triode Q1, biasing resistor R1, R2 and partially installing capacitor C2.Detector diode D1, coupling capacitance C1 and signal amplifying triode Q1 are serially connected with between circuit input end and the flash of light integrated circuit die I C.Output in chip IC is connected to light-emitting diode D2, D3, is used for when incoming call luminous.This incoming call flashing circuit for lamp 8 is contained on the wiring board 7, and wiring board then is fixed between the upper and lower cover, and circuit is by two button cell 81 power supplies that are contained in the 1.5V in the lower cover.Above-mentioned light-emitting diode is contained in the two ends up and down of wiring board.
Operation principle of the present utility model as shown in Figure 3, when mobile phone incoming call or conversation, electric wave signal is from the input of A end, through detector diode D1 detection, triode T1 amplification is delivered in coupling capacitance C1 coupling, promotes flash of light integrated circuit die I C work, and light-emitting diode is flashed.
