The invention discloses an intelligent temperature and humidity sensing loudspeaker which comprises a box body, an operation and LCD display unit, a control panel, a power supply unit, a power amplifier unit, an audio signal input unit and a horn unit externally connected with the box body, which the operation and LCD display unit, the control panel, the power supply unit, the power amplifier unit and the audio signal input unit are installed on the box body. A temperature and humidity sensor input unit is further installed at the bottom of a front panel of the box body, a MCU is installed in the middle, and an A / D conversion unit is installed in a central region in the box body. The temperature and humidity sensor input unit acquires the temperature and the humidity surrounding the loudspeaker and transmits the temperature and the humidity to the A / D conversion unit electrically connected with the temperature and humidity sensor input unit. The A / D conversion unit converts the temperature and the humidity into corresponding digital information and transmits the digital information to the MCU electrically connected with the A / D conversion unit. The MCU receives the digital information, performs calculation according to different noise data, invokes a corresponding adjustment scheme after calculation and automatically adjusts sound field modes and the volume of the loudspeaker.
Description
technical field [0001] The invention relates to an audio device, in particular to a temperature-humidity sensing intelligent audio system. Background technique [0002] The speaker is the terminal of the entire audio system, and its function is to convert audio power into corresponding sound energy and radiate it into the space. It is an extremely important part of the audio system, because it is responsible for the key task of converting electrical signals into acoustic signals for human ears to listen directly to. It has to deal directly with human hearing, which is very sensitive. And it has a strong ability to distinguish the timbre of complex sounds. Since the human ear's subjective experience of sound is the most important criterion for evaluating the sound quality of an audio system, it can be considered that the performance of the speaker plays a key role in the playback quality of an audio system. [0003] Under different environmental conditions (mainly temperatu...
