Embodiment 1

[0064] figure 1 A flow chart of a sound synthesis method provided by an embodiment of the present invention is shown, and the method can be used for low-speed warning sound reminders of electric vehicles. Specifically, the method includes the following steps:

[0065] Step S101: Receive the current engine speed.

[0066] Specifically, when it is used as a simulation application, the user can directly input the engine speed value as the current engine speed; when it is actually used in the vehicle, the engine speed at the current moment sent by the receiving module is used as the current engine speed; wherein, the acquisition module can be It is a CAN bus or a speed sensor.

[0067] Step S102: Find the first sound parameter data corresponding to the first engine speed adjacent to the current engine speed and the second sound parameter data corresponding to the second engine speed.

[0068] The above-mentioned sound parameter data refers to sound data at a fixed speed, such a...

Embodiment 2

[0116] Such as image 3 As shown, on the basis of Embodiment 1, the embodiment of the present invention provides another sound synthesis method, which also includes:

[0117] Step S301: output the audio output value.

[0118] Specifically, the audio output value is output at the audio output moment.

[0119] In one embodiment, the step of outputting the audio output value may be performed in one of the following ways:

[0120] refer to Figure 4 ,method one:

[0121] Step S401: Perform digital-to-analog conversion on the audio output value to generate an analog audio signal.

[0122] Step S402: Outputting the above-mentioned analog audio signal.

[0123] Through the above steps, the output of the analog audio signal at the audio output moment can be realized.

[0124] Specifically, the synthesized audio output value is transmitted to the digital-to-analog conversion module for data conversion, the digital audio signal (audio output value) is converted into an analog audi...

Embodiment 3

[0129] Figure 5 A schematic structural diagram of a sound synthesis device provided by an embodiment of the present invention is shown, and the sound synthesis device can be used for low-speed warning sound reminders of electric vehicles.

[0130] Specifically, the sound synthesis device includes: an input module 100 , a sound query module 200 , a sound source correspondence module 300 , a ratio generation module 400 and a synthesis module 500 .

[0131] Wherein, the input module 100 is used for receiving the current engine speed.

[0132] The sound query module 200 is used for finding the first sound parameter data corresponding to the first engine speed adjacent to the current engine speed and the second sound parameter data corresponding to the second engine speed.

[0133] The sound source correspondence module 300 is used for acquiring first sound source data of the first sound parameter data and second sound source data of the second sound parameter data.

[0134] The...

Abstract

The invention provides a sound synthetic method and device and electronic equipment and relates to the technical field of vehicles. The sound synthetic method and device and the electronic equipment aim at alleviating the technical problems in existing electric vehicles that the safety coefficient is low, the user demands cannot be met and the user experience degree is low, can improve the user experience and are conducive to improvement of the safety coefficients of the electric vehicles. The method includes the steps of receiving a current engine rotation speed; searching for first sound parameter data corresponding to a first engine rotation speed proximal to the current engine rotation speed, and second sound parameter data corresponding to a second engine rotation speed; obtaining first sound source data of the first sound parameter data and second sound source data of the second sound parameter data; on the basis of the current engine rotation speed, the first sound parameter data and the second sound parameter data, generating a sound mixing proportion of the first sound source data to the second sound source data; according to the sound mixing proportion, the first sound source data and the second sound source data, synthesizing an audio output value.
