Problems solved by technology

Among them, the variable valve will affect the torque of the car, affect the dynamic performance of the car, and the cost is high; the sound wave simulation is to generate corresponding audio signals based on the car running data of the car OBD, which is played by the car audio. Therefore, the driver cannot use the car audio to obtain a higher-quality sound experience while feeling the sound waves

Abstract

The invention provides an engine sound conducting device with simple and reliable structure. The engine sound conducting device with simple and reliable structure can effectively improve the sound quality in a cockpit to improve the whole vehicle driving pleasure when the environmental-protection law requirements are met and the vehicle dynamic quality is maintained. The device comprises an uppercover and a lower cover buckled with each other; the upper cover is provided with a first sound cavity and a second sound cavity; the lower cover is provided with a third sound cavity and a fourth sound cavity under the first sound cavity and the second sound cavity; a first sound diaphragm is arranged between the first sound cavity and the third sound cavity; a second sound diaphragm is arrangedbetween the second sound cavity and the fourth sound cavity; the first sound cavity is provided with an opening for communicating with an engine intake pipe; and the fourth sound cavity is provided with an opening for communicating with an acoustic tube.

Description

technical field [0001] The invention relates to the technical field of automobile acoustic components, in particular to an engine sound wave conduction device. Background technique [0002] The sound quality of the current car is already an important indicator to measure the quality of the car brand. The high-pitched engine sound and thick exhaust sound can often arouse the driver's stronger driving desire, but with the increasingly stringent environmental protection regulations in various countries, large-displacement engines have gradually become a rare product. The progress of automobile sound insulation technology not only isolates tire noise and wind noise, but also isolates the sound of engine and exhaust system from the outside of the car. At present, there are three mainstream ways to enhance engine and exhaust sound waves: variable valves for exhaust systems, sound wave conduction, and sound wave simulation. Among them, the variable valve will affect the torque of...
