Abstract

The invention discloses a window talkback device and method of an infrared carrier wave transmission signal based on powering of magnetic induction. An auxiliary talkback device power supply is charged in a magnetic induction mode and the infrared wireless transmission technology is adopted in audio transmission between a main talkback device and an auxiliary talkback device. The window talkback device and method of the infrared carrier wave transmission signal based on powering of the magnetic induction are mainly applied to occasions of counter window inside-outside talkback such as banks and hospitals and used for finishing audio double-direction synchronous transmission of the inside of the window and the outside of the window. In addition, an outdoor machine is designed to be a wireless panel, so that fixing by pasting or punching and wire laying in installation is omitted. The microphone-rod-free panels which are identical in appearance are adopted in the main talkback device and the auxiliary talkback device and a full duplex hands-free manner is adopted in the talkback process, so that voices of two sides can be clearly distinguished even if both sides talk at the same time.

Description

technical field [0001] The invention relates to a window intercom device, in particular to a window intercom device and method based on an infrared carrier transmission signal powered by magnetic induction. Background technique [0002] At present, the outdoor intercom panel of the traditional window intercom device is generally bonded to the window glass. Since the tempered glass is inconvenient to punch holes, the connection wire needs to bypass the glass and connect to the indoor unit through the hole at the bottom of the counter during installation. Affecting the appearance also increases the difficulty of installation. The intercom process adopts the PTT mode. Although two-way intercom is possible, the simultaneous speech during the communication process will be easily interfered and the sound quality is not clear enough. Therefore, this existing equipment has complicated installation process, exposed transmission lines, and the signal is easily interfered. Talk about ...
