The invention discloses a power amplifier debugging method and device, a sound generation method and device, equipment and a medium, and the power amplifier debugging method comprises the steps: obtaining a first signal and a second signal based on the driving information currently transmitted by a vehicle bus and the parameter value of a sound source parameter under all working conditions, the first signal representing the sound source signal of an active sound wave, and the second signal representing the sound source signal of the active sound wave; the second signal represents a sound source signal of the warning sound; based on the playing effect of playing the first sound by the loudspeaker in the vehicle and / or the playing effect of playing the second sound by the loudspeaker outside the vehicle, debugging to obtain parameter values of sound channel parameters of each sound channel of the power amplifier equipment under a plurality of working conditions; the first sound is obtained by processing a first signal through a first sound channel, the second sound is obtained by processing a second signal through a second sound channel, and the plurality of working conditions comprise at least one of a warning sound working condition and a non-warning sound working condition. According to the scheme, the power amplifier equipment can be debugged under the condition that the vehicle is provided with the pedestrian warning sound system and the active sound system at the same time.
Description
technical field [0001] The present application relates to the technical field of sound synthesis, and in particular, to a power amplifier debugging method, a sound generation method and apparatus, equipment and medium. Background technique [0002] In recent years, new energy vehicles such as electric vehicles have become increasingly popular. However, in real scenarios, there are more or less hidden dangers in new energy vehicles. Taking an electric vehicle as an example, it may be too quiet when driving at low speed, and pedestrians may not be able to perceive that an electric vehicle is passing by, so there is a risk of pedestrian collision. In the process of driving the electric vehicle at low speed, the external speaker can be used to issue a warning sound to remind pedestrians. [0003] In addition, in order to improve the user's driving experience, electric vehicles will not only be equipped with the above-mentioned pedestrian warning sound system, but also an activ...
