Problems solved by technology

[0003] However, the interior space of the car is relatively narrow, the placement of the speakers is fixed, and the loudspeakers in the high-frequency range are more directional, so the sound effects heard at different positions in the car are quite different; at the same time, the positioning of the sound field requires a mid-range speaker Work together with the tweeter to have a better effect
Mode switching to enhance the hearing effect in a specific position requires manual settings, and the driver cannot distract himself from manual operation during driving, and may sacrifice the hearing effect in other positions

Abstract

The embodiment of the invention discloses a vehicle-mounted loudspeaker adjusting device and method, and the device comprises a voice receiving module, a control module and a motor which are connectedin series; the motor is connected with a vehicle-mounted loudspeaker through a steering mechanism, and the voice receiving module is used for determining an electric signal according to a received voice signal and sending the electric signal to the control module; the control module is used for determining a control instruction according to the electric signal; and the motor is used for adjustingthe angle of the vehicle-mounted loudspeaker through the steering mechanism according to the control instruction. Voice signals of a driver or passenger in a vehicle are received through the voice receiving module, the voice signals are processed, a control instruction is determined, the motor adjusts the angle of the vehicle-mounted loudspeaker through the steering mechanism according to the control instruction, so the problem that the angle of the vehicle-mounted loudspeaker in the vehicle cannot be adjusted is solved, the driver or passenger can achieve the effect of adjusting the angle ofthe vehicle-mounted loudspeaker through voice, manual setting is not needed, the best music playing effect is achieved while driving safety is guaranteed, and user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of speaker control, and in particular, to a vehicle-mounted speaker adjustment device and method. Background technique [0002] With the improvement of the user's quality of life and the demand for personalization and entertainment of the driver's space in the car, the current automotive market's requirements for car audio effects have been increasing. Car manufacturers configure branded audio systems or a larger number of car speakers for car products to improve sound quality and increase product charm and user attraction. Car speakers are multiple speakers fixed in different positions inside the vehicle, including tweeters, woofers and midrange speakers, etc., which emit sound by receiving the alternating signal output by the power amplifier. [0003] However, the interior space of the car is relatively narrow, the placement of the speakers is fixed, and the loudspeakers in the high-...
