Abstract

An electric motorcycle engine sound effect generator can generate various simulated traditional motorcycle engine sound effects according to the speed and road conditions of the electric motorcycle. At present, the electric motorcycle is driven directly by the motor, so it is very quiet when driving, and there is no engine noise. This creation of the electric motorcycle engine sound effect generator is used to remind other vehicles and passers-by that an electric motorcycle is approaching, so as not to hear the sound of the car. Accidents, etc., while also providing electric motorcycle riders with extra engine sound fun. The electric motorcycle engine sound effect generator device includes a sound effect selection unit, an electronic accelerator detection unit, a microprocessor unit, and a sound effect generation unit.

Description

Electric motorcycle engine sound generator

This creation is about an electric motorcycle engine sound effect generator, especially a traditional motorcycle engine sound effect that can generate various simulations. Accidents, etc., and at the same time provide electric motorcycle riders with the extra riding pleasure of traditional motorcycle engine sounds.

Because the current electric motorcycle is driven directly by the motor, it is very quiet when driving, and there is no engine noise. However, because of its quietness, other vehicles and passers-by on the road often do not pay attention or do not know that the electric motorcycle is approaching or will be nearby. overtaking, resulting in a car accident.

In addition, although today is an era of environmental protection, electric motorcycles have made a great contribution to reducing air pollution, but some motorcyclists still love the engine sound of traditional motorcycles, which electric motorcycles cannot give, which makes When consumers buy motorcycles, it is difficult to choose between electric motorcycles and traditional motorcycles.

Therefore, this creation provides an electric motorcycle, which can not only generate the sound of a traditional motorcycle engine to remind other vehicles on the road and passersby that an electric motorcycle is approaching, but also provide electric motorcycle riders with additional traditional motorcycle engine sound effects to ride car fun.

The purpose of this creation of an electric motorcycle engine sound effect generator is to remind the road Other vehicles come close to passers-by with electric motorcycles, while also providing the riding pleasure of electric motorcycle riders who love the sound of traditional motorcycle engines.

In order to achieve the above purpose, this creation of an electric motorcycle engine sound effect generator includes a sound effect selection unit, an electronic throttle detection unit, a microprocessor unit, and a sound effect generation unit; the sound effect selection unit stores various traditional motorcycle engine simulation sound effects in advance. , the user can select the sound of the traditional motorcycle engine through the sound selection unit according to their preferences, so as to output a simulated engine sound signal; the electronic throttle detection unit is used to detect the motor speed and load torque of the electric motorcycle. It outputs an analog signal of engine horsepower and torque value; the microprocessor unit is a microcontroller, which is connected with the sound effect selection unit and the electronic throttle detection unit to receive the engine sound effect signal and the engine horsepower and torque values. The signal is used to output a corresponding traditional motorcycle engine sound signal; the sound effect generating unit is connected with the microprocessor unit to receive the corresponding traditional motorcycle engine sound signal to output an engine sound.

[Figure 1] is the block flow chart of this creation.

Please refer to Figure 1 for the block diagram flow chart of the electric motorcycle engine sound effect generator. This creation of an electric motorcycle engine sound effect generator includes a sound effect selection unit 11, an electronic throttle detection unit 12, a microprocessor unit 13, and a sound effect generation unit 14; the sound effect selection unit 11 stores various traditional motorcycle engine simulation sound effects in advance , the user can select the sound of the traditional motorcycle engine through the sound effect selection unit 11 according to their preferences, so as to output a simulated engine sound effect signal; the electronic throttle detection unit 12 is used to detect the motor speed and load torque of the electric motorcycle ,by Output analog signal of an engine horsepower and torque value; the microprocessor unit 13 is a microprocessor, connected with the sound effect selection unit 11 and the electronic throttle detection unit 12 to receive the engine sound signal and the engine horsepower and The torque value signal is used to output a corresponding conventional motorcycle engine sound signal; the sound effect generating unit 14 is connected to the microprocessor unit 13 to receive the corresponding conventional motorcycle engine sound signal to output an engine sound. For example, when a motorcycle starts, the engine sound is brisk. As the driving speed increases, the engine speed increases, and the engine sound gradually increases. When climbing a hill, the load torque increases, and the engine sound is relatively low; the microprocessor The unit 13 receives the signals of the sound effect selection unit 11 and the electronic throttle detection unit 12; the sound effect generation unit 14 uses the signals of the sound effect selection unit 11 and the electronic throttle detection unit 12 to transmit the signals through the microprocessor unit 13 To the sound effect generating unit 14, the sound of a traditional motorcycle engine is generated to simulate the sound effect of an electric motorcycle engine under different rotational speeds, different torques and different terrains.
