Problems solved by technology

[0004] However, adjusting the volume according to the rotational speed of the engine and the preset comparison table not only requires an additional complex sensor to detect the rotational speed of the transmitter, but also can only be adjusted according to the preset comparison table, and the volume adjustment range is limited
Moreover, in practical applications, the noise generated by the operation of the engine is not the only factor affecting the playback effect of the player

Abstract

The embodiment of the invention discloses a vehicle-mounted player, and relates to the technical field of navigation. The volume of the vehicle-mounted player can be effectively adjusted under the condition that no additional device is added, and the playing effect of the vehicle-mounted player is improved, thereby improving the listening experience of a user in a vehicle. The specific scheme is that a microphone is used for detecting the current environmental noise in the vehicle; a storage module is used for storing the initial environmental noise, and storing the initial play volume set bythe user; a calculation module is used for calculating the play volume Y under the current environmental noise through employing Y=delta(step)*K+B or Y=(A-A0)*K+B; an adjustment module is used for adjusting the volume of the vehicle-mounted player to the play volume calculated by the calculation module.

Description

Technical field [0001] The present invention relates to the technical field of navigation, in particular to a vehicle-mounted player. Background technique [0002] During the driving process of the vehicle, the operation of the engine will produce noise, which may interfere with the audio signal played by the player in the vehicle and affect the performance of the user. [0003] In response to this problem, the patent CN105845163A discloses a car player based on vehicle speed measurement that adjusts the volume adaptively, and discloses the following technical features: during the driving process of the vehicle, the Hall sensor arranged in the car engine generates and rotates with the engine rotor The square wave pulse signal corresponding to the situation; according to the square wave pulse signal and wheel data, the speed of the car is calculated, and the corresponding table of the speed and the amplification volume is set in advance to find the amplification volume corresponding...
