The utility model will be further described below in conjunction with embodiment for embodiment.
As shown in Figure 1, a kind of micro radio earphone comprises earphone body 1, also is provided with magnetic wave transducer 2; Described earphone body 1 comprises the housing 11 of front end perforate, the panel 12 that is located at housing 11 afterbodys, the loud speaker 13 that is located at housing 11 inner spaces and reception amplifier 14 and battery compartment 15, loud speaker 13, reception amplifier 14 and battery compartment 15 are electrically connected successively, and panel 12 corresponding battery compartments 15 places are provided with corresponding opening; Described magnetic wave transducer 2 comprises capacitor C 1, inductance L 1 and sensor coil L2.Behind audio signal input magnetic wave transducer 2, around the magnetic wave sensor coil, can form a magnetic field.When audio signal changed, magnetic field also changed thereupon.The audio signal of corresponding front, the magnetic field of variation can produce a kind of smaller electric current on the receiving coil of earphone body.The signal of this receiving coil is exaggerated and converts to audio signal.
As shown in Figure 2, described panel 12 is provided with draw-out handle 16.Draw-out handle 16 is specifically designed to earphone body 1 is taken out in duct.Draw-out handle 16 will be convenient to pull out the earphone body also will have disguise simultaneously, preferably adopts transparent material to make.Described draw-out handle 16 is transparent high intensity line.
As shown in Figure 1, front end perforate 111 places of described housing are provided with anti-earwax net 17.Anti-earwax net 17 is used to prevent that the earwax in the duct from stopping up front end perforate 111 so that can't hear the sound that the earphone body sends.
As shown in Figure 2, described panel 12 is provided with volume by-pass cock 18.The user can regulate the size of volume to adapt to different environment.
As Fig. 1, shown in Figure 3, described battery compartment 15 places are provided with battery door 19, one side an end of battery door and being dynamically connected of battery compartment opening 121.The mode that adopts hinge to be dynamically connected in the present embodiment.Also can adopt battery door in the fixing mode of battery compartment opening part chucking.Battery compartment 15 places are provided with battery contact spring 152.
As shown in Figure 5, described reception amplifier 14 comprises inductance L 3, one-level amplifier 141 and amplifier 142, and the three is electrically connected successively.Volume by-pass cock 18 is connected with amplifier 142.Above-mentioned electrical principle is more application in the prior art.As shown in Figure 6, inductance L 3 is connected to one-level amplifier 141, both make one in an embodiment, one-level amplifier 141 can substitute with triode, the output of one-level amplifier is connected to amplifier 142, amplifier output connects loud speaker 13 (SPK), and volume by-pass cock 18 (R1) is connected on the amplifier 142.
As shown in Figure 1, described magnetic wave transducer 2 also is provided with input interface 21, and described sensor coil L2 passes inductance L 1.Input interface 21 is connected with inductance L 1, and input interface 21 adopts 3.5 or 2.5 millimeters jack interface, adopts 3.5 millimeters jack interface in the present embodiment.As shown in Figure 4, inductance L 1 is connected with capacitor C 1.
During use, open battery door 19, headset batteries is installed, battery door 19 is advanced in the battery compartment 15, earphone body 1 is put into ear with finger; Magnetic wave transducer 2 is hung under the neck, the output of earphone such as driving arrangement such as mobile phone, intercom is connected to the input interface of magnetic wave transducer 2, and driving arrangement is hidden in the clothing, driving arrangement arrives magnetic wave transducer 2 with the information conveyance that receives, by sensor coil L2 with in the earphone body 1 of induction of signal in the duct, earphone body 1 is enlarged into audio signal with the electromagnetic induction signal conversion that receives, and the recipient can hear sound clearly.
The utility model is a kind of micro radio receiver that converts audio signal by electromagnetic induction to.Mainly be applicable to some objectively inconvenient occasions that maybe can not expose earphone wire or earphone itself that expose.
