Description of the invention Q) (Please read the notes on the back before filling out this page) The invention relates to a speakerphone for hands-free intercom for mobile phones, especially a vehicle When a mobile phone receives a signal while walking, it can be used for mobile without talking with the hands (hands-free). The hands-free interphone pickup for the phone. 5 Due to the rapid spread of mobile phones, the number of accidents caused by the use of mobile phones by drivers while driving has recently increased dramatically. Here, in accordance with the amendments to the Road Traffic Law, we hope to limit the use of mobile phones while driving. However, in the case of hands-free use, traffic penalties will not be violated. The danger of using a mobile phone while driving has been pointed out before, and the need for hands-free intercom has been known from 10 years ago, and many device cases have been proposed to implement this form.

For hands-free use of 15 pickups. The example of the form used to install the pickup-Qin Yuan group, the unit group contains a speaker and includes a body part. The body part is provided with an input terminal for a microphone with a wire and a handset of the mobile phone body. A terminal-attached wire for connecting a microphone terminal. When using this example in a car, connect the wires of the main body to the input terminal of the microphone-20 of the mobile phone body, set the main body to an appropriate position next to the driver's seat, and install the microphone connected to the main body. Near the driver's face in the car, such as at the frame of the windshield. In addition, the power supply of the main body is provided through a connection line of a cigarette lighter socket in the vehicle. Then, when receiving in this form, the switch of the main body can be turned ON-this paper size applies the Chinese National Standard (CNS) A4 (210X297 mm) printed by the Intellectual Property Bureau of the Ministry of Economic Affairs and Consumer Cooperatives 507466 A7 B7 5 2. In the state of the invention description (2), while listening to the sound through the speaker of the main body, while speaking through the microphone, you can talk in a hands-free state. However, the aforementioned mobile phone with hands-free performance is the one with the speaker ^ hidden in the mobile phone, which makes the sound output limited, and the microphone is also used. 5 The form embedded in the mobile phone body, resulting in the mobile phone body Must be installed very close to the driver, there are many restrictions on use. In addition, in the example of the built-in type pickup of the speaker, the power supply for the speaker is taken from the cigarette lighter socket (12V / 24V), so that the output of the speaker is limited. In addition, when this type of microphone is connected, noise can be collected through the connection line, which will hinder the call. Depending on the positional relationship between the microphone and speaker, howling will also occur. In addition, the power source can be sourced not from the terminal of the cigarette lighter socket, and a battery for the power source can be installed, but the problem of increasing the size of the device and increasing the cost arises. The present invention is constituted to solve the foregoing problems, and its object is to provide a hands-free interphone pickup for mobile phones. It is not necessary to hold a mobile phone, that is, to talk in a hands-free state, so as to output high-quality sounds without murmurs or howling. ^ The invention of item 1 of the scope of patent application is a hands-free interphone pickup for mobile phones. The pickup includes: 20-the main body, which is provided with a sound conversion A sound signal for providing a microphone for a mobile phone, and a light emitting section for converting the sound signal provided by the aforementioned mobile phone into infrared light and transmitting; and a receiver section, which is provided with: After receiving the infrared light transmitted by the aforementioned main body, it is converted into a sound-receiving unit and an _____ 笛 si_.
