Engine sound simulator

Abstract

The invention relates to equipment using an electronic device to simulate the sound of various engines. The equipment is characterized in that the running sound of the engines of an airplane model, a vehicle model, a boat model and a toy is simulated by a sound sampling and voice synthesis method. The problem that the inherent sound experience of the engine cannot be vividly played back by the current electrically driven model or toy is solved. The engine sound simulator can simulate the running sound of the engine workings at starting, each rotation speed, acceleration, deceleration and shut down states. The engine sound simulator comprises a signal acquiring module, a voice synthesis module and an audio amplifying module. According to the engine sound simulator, the signal acquiring module is utilized to acquire an accelerator signal of a remote controller, the rotation speed signal of an electric motor and the like to acquire the running information and rotation speed state information of the engine; a voice synthesizer acquires a rotation speed signal of the engine, the rotation speed signal is input to the voice synthesizer, after synthesizing a sound source sample, sampled in advance, of engine sound through algorithm, the voice synthesizer outputs audio data matched with the state and rotation speed, after being converted into a simulated sound source signal, the audio data is input to the audio amplifying module, and through audio power amplification, a loudspeaker is driven to give vivid engine sound. Therefore, the model, the toy or the like which are electrically driven have a more vivid sound effect.

Description

Technical field [0001] The invention relates to an electronic device for simulating engine sound when the engine is running. The device is used for simulating the sound of various aviation, vehicle, and ship engines when starting, accelerating and decelerating, and at a specific speed. Used in aviation models, vehicle models, nautical models, children's toys and other fields. Its characteristic is that it can emit realistic aviation, vehicle, and ship engine sounds on models and toys powered by electric drive through this electronic device, and obtain good simulation effects and auditory sensory experience. Background technique [0002] At present, with the development of new energy, fuel power such as methanol engines and gasoline engines used in aviation models, vehicle models, nautical models and children's toys has been gradually replaced by electric motors. [0003] When the electric motor is working, compared with the engine, it has the characteristics of simple structure, s...

AI Technical Summary

Problems solved by technology

Although this method can produce a sound similar to an engine, there is a big gap between the simulation degree and effect of the sound and the real engine sound

At the same time, due to the principle of mechanical structure, there are disadvantages such as large volume, complex structure, low sound simulation, and difficulty in changing the sound.
