Abstract

The invention relates to a photon key with audio play function. The photon key comprises a light signal emitting module and an audio signal processing module, wherein the light signal emitting module is used for emitting a light signal containing an unlocking password; a digital audio file is stored in the light signal emitting module, and the audio signal processing module is used for converting the digital audio file into an analogue audio file. The light signal emitting module and the audio signal processing module of the photon key with audio play function provided by the invention are optimized and combined, so that compared with the current photon key or the currentaudio player, the photon key provided by the invention has more functions; and compared with the combination of the current photon key and the current audio player, the photon key provided by the invention is small in size, low in price and convenient to carry and use.

Description

technical field [0001] The invention relates to a client terminal of an access control system, in particular to a photon key with an audio playback function. Background technique [0002] MP3 is an audio compression technology, and its full name is Moving Picture Experts Group Audio Layer III (Moving Picture Experts Group Audio Layer III), referred to as MP3. MP3 uses the insensitivity of the human ear to high-frequency sound signals, converts time-domain waveform signals into frequency-domain signals, and divides them into multiple frequency bands, uses different compression rates for different frequency bands, and increases the compression ratio for high frequencies (even ignore the signal), use a small compression ratio for low-frequency signals to ensure that the signal is not distorted. In this way, it is equivalent to discarding the high-frequency sound that is basically inaudible to the human ear, and only retaining the low-frequency part that can be heard, so that t...
