Abstract

The utility model relates to a mobile telephone converter, which is composed of a receiving circuit, an amplifying circuit, a transmitting circuit, a printed circuit board, and a clamping mechanism, wherein, the printed circuit board is welded with electronic elements which form the circuits, and the clamping mechanism can lead a converter box body to be fixed onto a mobile telephone receiver. The utility model is characterized in that the converter is cooperated with an FM radio receiver; sound received from the mobile telephone receiver can be sent into the FM radio receiver and can be played after conversion, and therefore, under the condition of a mobile telephone being inconveniently held by hand, the method can lead the voice of the other party to be heard and can lead a person to talk with the other party. The utility model is especially suitable for drivers to use when driving.

Description

The mobile phone transducer

The utility model relates to a kind of electrical communication technology, particularly mobile phone receiver sound is received and is sent to the mobile phone transducer in the FM receiver.

Prior mobile phone does not possess hand-free function, so the user must abut in the other sound that send the words people of just not hearing of ear with receiver by handset telephone.At some special occasions, particularly drive a car in the way, the user must drive or stop and can converse with the other side by one hand, and this is extremely inconvenient to the user.

The purpose of this utility model is to provide a kind of sound that the mobile phone receiver can be spread out of to convert to can be through the mobile phone transducer of fm band broadcast.

Technical solution of the present utility model is: the mobile phone transducer comprises receiving circuit, amplifying circuit and radiating circuit, its special character is, be welded with the formation receiving circuit, the printed substrate of the electronic component of amplifying circuit and radiating circuit is arranged in the box body and makes the electrostatic microphone in the receiving circuit relative with opening on the box body roof, box body is provided with the clamp system that box body can be fixed on the mobile phone receiver, and it is by two clamp arms that are symmetricly set on the box body both sides, link to each other with clamp arm one end and the opening on box side wall stretches into the travelling arm in the box body and the reset tension spring that two travelling arms link to each other formed.

On the medial surface of a clamp arm, vertically be provided with projection, on the box body side arm therewith corresponding position, projection position have a hole, from then on projection stretches in the hole in the box body and is against on the mains switch of transducer, in order to the break-make of control transformation device power supply.Make its receiver place that is clipped in mobile phone when two clamp arms outwards draw back, projection with outside move, it will break away from mains switch, mains switch closure, the power connection of transducer.Not the time spent, take off transducer, under the effect of reset tension spring, two travelling arms drive to move in the clamp arm and reset, and clamp arm leans against on the box side wall, and the hole of projection on box side wall stretched into and be against in the box body on the mains switch, and mains switch disconnects.Adopt the manually mains switch of control transformation device of this structure.

Described travelling arm is positioned at the chute of box body bottom, and the top of chute is provided with cover plate, and printed substrate is positioned at the top of cover plate.

Characteristics of the present utility model are: transducer matches with FM receiver, can after conversion, send in the FM receiver sound of the mobile phone receiver that receives and play back, thereby be not easy under the situation of handset telephone, adopt said method just can clearly hear the other side sound and with its conversation, the driver in the way that is particularly suitable for driving a vehicle uses.This transducer simple in structure, compact, volume is little, easy to carry.

Fig. 1 is circuit theory diagrams of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the cutaway view of Fig. 2.

Be described in further detail below in conjunction with accompanying drawing:

In circuit theory diagrams shown in Figure 1, the receiving circuit of transducer is by electrostatic microphone HT ₁, resistance R ₁, capacitor C ₈, C ₄Form.Amplifying circuit is by triode T ₁, resistance R ₂-R4, capacitor C ₁Form.Radiating circuit is by inductance L ₁, capacitor C ₂, C ₅Form.Tranmitting frequency is 100～105MHz, K ₁Be mains switch, power supply is No. 5 batteries of 1.5 volts at a joint.

Fig. 2,3 has provided the structural representation of transducer, and the box body of transducer (1) is a cuboid, and the lower end that is symmetricly set on the clamp arm (2) of box body both sides is connected with orthogonal travelling arm (3), and the shape of two arms is the L type.The two travelling arms opening on the box body two side respectively stretch into box body and are positioned at limit sliding chutes on the bottom surface, are connected with reset tension spring (5) between two travelling arms.Put on the chute and be provided with cover plate (6), being fixed by screw (4) is connected on the pillar (7) that is positioned on the bottom surface.Above cover plate, be provided with the printed substrate (8) that is welded with the electronic component that constitutes transducer.Opening (10) on electrostatic microphone on the wiring board (9) and the box body roof is oppositely arranged.Mains switch then with a clamp arm on projection (11) be oppositely arranged, be vertically set on the clamp arm medial surface projection through with the corresponding box side wall of projection on the hole stretch in the box body and be against on the mains switch (12).Battery then is arranged in the box body and printed substrate, opposite side that travelling arm is relative.The roof of box body is removable removable wall with the sidewall relative with battery.

At first should debug before the use, promptly the transducer clamp arm be drawn back, energized facing to the speech of the microphone of transducer, is opened FM receiver then simultaneously, with frequency tuning in 100～105MHz scope until broadcasting speech clearly.During use, the clamp arm of transducer is drawn back and is clipped on the receiver of mobile phone, make the electrostatic microphone of transducer aim at the receiver of mobile phone.When needs are got phone or have phone to make, the normal running phone, and turn on broadcast receiver, and just can from broadcast receiver, hear the other side's speech, user's the words of sending are still passed to the other side by the microphone of mobile phone.Like this, just needn't abut in one's ear by cell-phone.

Claims

1, a kind of mobile phone transducer, comprise receiving circuit, amplifying circuit and radiating circuit, it is characterized in that being welded with the formation receiving circuit, the printed substrate of the electronic component of amplifying circuit and radiating circuit is arranged in the box body and makes the electrostatic microphone in the receiving circuit relative with opening on the box body roof, box body is provided with the clamp system that box body can be fixed on the mobile phone receiver, and it is by two clamp arms that are symmetricly set on the box body both sides, link to each other with clamp arm one end and the opening on box side wall stretches into the travelling arm in the box body and the reset tension spring that two travelling arms are connected formed.
