Description of the invention: [Technical field of the invention] The present invention relates to a walkie-talkie, in particular, by setting a signal amplifier inside the earphone to shorten the transmission distance between the microphone and the amplifier, and The connector is connected to the transmission line, one-way transmission {or touch signal, to improve the quality of the call, easy to use, and reduce the cost of the car walkie-talkie. [Prior Art] The locomotive is a very convenient transportation tool. Whether it is working in the city or traveling to the suburbs, it can effectively save time for traffic jams. However, when the stalker rides a locomotive, because the helmet is wearing a helmet and the ribs are too loud during driving, it often makes it difficult for the front and the rear to pass, but not when riding the locomotive. A moment of leisure and comfort. In order to solve the above problem, the production of the organic car helmet intercom is still able to talk to each other when the two people take the helmet in the second (four) car area. Please refer to Figure 5. The conventional locomotive helmet intercom includes: a set of earphone microphone a, a set of 々-, friend b and host C, and each of the connecting lines b is provided with two transmission lines (bl, b2). The second user can connect the headset b to the earphone microphone a and the host to the 7 ears to achieve the purpose of two-way conversation. c = 纮 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当After cl put 1294251' t, the fine m and the miscellaneous n_ are amplified, and the function of isolating noise interference is transmitted on the transmission line of the other side of Wei Wei, but the cost is relatively increased. In addition, when the locomotive is in front of and behind: when the person talks, it must be connected by the host c, and the number is enlarged, which is quite inconvenient in use. In view of this, in order to improve the above-mentioned shortcomings, the walkie-talkie can not only facilitate connection, reduce cost, but also reduce noise interference, to improve call quality, the inventor has accumulated many years of experience and no research and development improvements, and the present invention produce. SUMMARY OF THE INVENTION The main object of the present invention is to provide a walkie-talkie, which can reduce noise interference by improving the call quality by setting the signal amplifier to the headphone_section, short microphone and amplifier. . A secondary object of the present invention is to provide a walkie-talkie, by shortening the transmission distance between the original signal and the amplification, so that when the signal is output to the outside of the earphone, it can directly reach the ear of the user, and can be low. Impedance transmission lines replace the isolation lines of conventional technology to reduce costs. Still another object of the present invention is to provide a walkie-talkie, wherein the signal amplifier is disposed inside the earphone and connected to each other by a corresponding connection member, and the host is separately connected to the transmission line by one-way output or receiving condition. For ease of use and lower costs. For the purpose of the above-mentioned invention, a walkie-talkie provided by the present invention comprises a headset, a connector, a microphone, two unidirectional transmission lines, and a connector. The earphone 1294251 has a - amplifier, an amplifier, and a power supply. One end of the connector is coupled to the earphone, and the other end is coupled to the microphone. The microphone of the microphone is electrically connected. The one-way transmission line of the two-way transmission line is connected to the microphone and the amplifier, and the other end is connected in combination! ! The plug-in is used to output the signal; the other end of the single-directional transmission line is connected to the amplifier inside the earphone, and the other end is combined with a jack provided in the connector to receive the signal.
