[Prior Art] The traditional wireless microphone does not have a built-in rechargeable battery, but a lot of installation: the battery of the market is powered by the battery. When the battery of the microphone is exhausted, it must be removed first. The new battery is more complicated. In addition, because the battery is low, the number of rabbits that replace the battery is enough. The number of babies is frequent, and the user must carry the spare general battery. Inconvenience to the user using the microphone. In order to improve this deficiency, there is a Taiwanese announcement No. M3696〇6, the external microphone, as shown in Figure i, the microphone U can be inserted into the slot 13 of the charging stand 12, so that the microphone 1 The charging chip contacts the charging end of the charging stand 12, and then one end of the power cable 14 is inserted into the jack 15 of the charging stand 12', and the other end is connected to the market, so that the microphone η can be charged" and the microphone 1 is charged. In the middle age, the following problems are caused: (1) The quality of power transmission is easily affected by the environment. The microphone 1 is electrically connected to the charging end of the charging stand 12 to achieve charging. However, the materials of the charging piece and the charging end are generally For copper, it is more susceptible to the influence of the environment, resulting in rust and power transmission. In addition, the charging base 2 and the power line M413293 14 are connected together, and if the _ _ ', - 70 pieces are lost or damaged, That is, the microphone 1 cannot be charged. Skillful (2) is easily affected by external force and cannot be continuously charged. Since the microphone 1 must be placed on the charging stand 12 in alignment with the insertion, the charging piece can be brought into contact with the charging end, _3 - shaking to the microphone 1 or the charging stand 12, so that the charging chip and charging no longer contact, will make the two can not form an electrical connection and power off. (3) Recharge by the mains is still subject to geographical restrictions. Since the charging stand 12 must be plugged into the mains socket through the power cord 14 with the transformer plug, the microphone can be charged but the mains socket is set in the building, if it is out of the house. It is difficult for the mains socket to charge the microphone, which is very inconvenient for the user. Since the current wireless microphone is still lacking in charging by using the charging stand, how to optimize the charging mode of the wireless microphone is a target that the relevant industry needs to improve. [New content] Therefore, the object of the present invention is to provide an infrared microphone that is charged by USB. Therefore, the infrared microphone with USB charging function includes a sound receiving unit capable of receiving an audio source signal, an oscillating circuit electrically connected to the sound receiving unit and capable of converting the sound source signal into an RF signal, and an electrical connection HM oscillation circuit and can be amplified An amplifying circuit of the RF signal, an infrared emitter electrically connected to the amplifying circuit, and a power supply unit for supplying power of the circuit, the sound collecting unit and the red M413293 external transmitter, wherein the infrared emitter can mix the RF signal After launching. The power supply unit includes a rechargeable battery that can turn the power out, a steady-state steady-current module electrically connected to the rechargeable battery, a USB power conversion module electrically connected to the regulated current-stabilizing module, and an electrical connection. The USB power conversion module can be connected to a USB cable. The effect of the novel is that the USB power conversion module can convert the power from the USB cable and store it in the rechargeable battery A as a power source for the infrared microphone; since the USB transmission specification is an internationally recognized specification. The USB power conversion module and the connection process are standardized to reduce the cost. Moreover, with the advantages of USB in the field of consumer electrical products, the new infrared microphone can overcome the geographical use. limit. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments.

And a connection 254 that is electrically connected to the USB power conversion module 253 and externally connected to a USB connection line φ26. In this embodiment, the connection port 254 is a USB slot for the USB connection line 26. Plug the plug. It should be noted that the USB (Universal Serial Bus) connector is designed to be quite durable and can be mass-produced at a relatively low price. The connectors used in the past are relatively fragile, even if the force is not strong, sometimes the pins or parts will bend or even Break _. The metal conductive part of the USB connector is protected by plastic. The entire connecting part is surrounded by a metal protective cover, and the metal protective cover can be electrically connected to the grounding end to provide a path for static electricity to be discharged, so as to avoid static electricity passing through the electronic component. Cause damage. In addition, the USB interface slot is not only easy to be inserted and removed, but also has a foolproof design. The plug in the opposite direction cannot be inserted into the socket. According to the above structure, the USB power conversion module 253 can source the USB cable 26. The cited power is converted and stored in the rechargeable battery 251 as a power source for the infrared microphone. Furthermore, since the USB transmission specification is an internationally recognized specification, the USB power conversion module 6 M413293 253 and the connection port are connected. The 254 process can be standardized to reduce costs. Moreover, with the advantages of USB in the field of consumer electrical products, the new infrared microphone can overcome the geographical limitation in use.
