Abstract

The embodiment of the invention provides a working state detection method and vehicle-mounted equipment, the vehicle-mounted equipment comprises a processor, a power amplifier and at least one loudspeaker, and the working state detection method applied to the vehicle-mounted equipment comprises the steps that the processor is controlled to output a first detection signal; based on the first detection signal, the power amplifier transmits an audio signal to the loudspeaker, so that the loudspeaker works; the processor is controlled to carry out AD signal acquisition on the loudspeaker to obtain a first detection result, and the first detection result is used for indicating a voltage value of the acquired AD signal; and determining the working state of the loudspeaker according to the voltage value indicated by the first detection result. According to the embodiment of the invention, the problem that the detection of the working state of the loudspeaker in the vehicle-mounted equipment is too complicated in the prior art is solved.

Description

technical field [0001] The present application relates to the field of in-vehicle equipment, and in particular, the present application relates to a working state detection method and in-vehicle equipment. Background technique [0002] At present, the car audio has almost become the standard equipment of the vehicle, and it is one of the core devices of the car entertainment system. Usually, each set of car audio includes at least one speaker, which is the sounding unit of the car audio and is a transducer device capable of converting electrical signals into acoustic signals. [0003] With the increase of on-board equipment in the vehicle, there are more and more related wiring harnesses, which makes the wiring more and more complicated. For complex wiring, it is especially important to detect the connection status of the wiring harness. Taking the speaker in the car audio system as an example, in the related art, a waveform with a fixed frequency can be used to scan the s...
