AI Technical Summary

⚠Technical Problem

Existing in-vehicle audio systems are not suitable for vehicles with three rows of seats and cannot effectively improve the auditory experience for passengers in the third row.

⚗Method used

In vehicles with three rows of seats, a first surround speaker, a second surround speaker, a first tweeter, a second tweeter, a first mid-bass speaker, and a second mid-bass speaker are arranged. The speakers are symmetrically positioned with reference to the vehicle's central axis and are placed above or on the sides of specific locations to reduce adverse effects on the ears. Speakers with specific transmittance and sensitivity ratings are used to ensure optimal sound quality within a suitable frequency range.

🎯Benefits of technology

By optimizing the speaker layout and parameter settings, the auditory experience of passengers in all three rows of seats has been improved, the sense of spatial distance in the sound field has been increased, and the overall acoustic quality and sound effects of the in-vehicle audio system have been improved.

Abstract

A vehicle (1), comprising: first-row seats (11), second-row seats (12), and third-row seats (13). An onboard audio system (14) corresponding to the third-row seats comprises: a first surround speaker (141), a second surround speaker (142), a first tweeter (143), a second tweeter (144), a first mid-bass speaker (145), and a second mid-bass speaker (146), wherein the first surround speaker and the second surround speaker are symmetrically arranged about the central axis of the vehicle on a headliner corresponding to the third-row seats, and the first surround speaker and the second surround speaker are both arranged at positions away from the ears of users in the third-row seats; the first mid-bass speaker and the second mid-bass speaker are symmetrically arranged about the central axis of the vehicle, and the first mid-bass speaker and the second mid-bass speaker are both arranged at positions above the plane where armrests of the third-row seats are located; and the first tweeter and the second tweeter are symmetrically arranged about the central axis of the vehicle. The auditory experience for users riding in a vehicle having three rows of seats can be improved.
