发明名称 Vehicle with sound wave reflector
摘要 Embodiments disclose a vehicle which has a vehicle ceiling having a first sound wave reflection portion having a first sound wave reflection characteristic and a second portion having a second sound wave reflection characteristic, wherein the first sound wave reflection portion is more sound wave reflecting than the second sound wave reflection portion and at least one speaker arranged in the vehicle, so that a main sound emission direction is directed to the first sound wave reflection portion, so that a sound wave emitted by the speaker and reflected by the first sound wave reflection portion is perceptible as a diffuse sound by a person in the vehicle.

主权项 1. A vehicle, comprising: a vehicle ceiling comprising a first sound wave reflection portion comprising a first sound wave reflection characteristic and a second portion comprising a second sound wave reflection characteristic, wherein the second portion is made of a material having a higher sound absorption coefficient than the first sound wave reflection portion, wherein a surface of the first sound wave reflection portion is more sound wave reflecting than a surface of the second sound wave reflection portion; and at least one speaker arranged in a headrest of the vehicle or in a speaker box which is attachable to a backrest or the headrest of a vehicle seat, so that a main sound emission direction is directed to the first sound wave reflection portion; wherein the surface of the first sound wave reflection portion is configured to reflect an incident sound wave, which is emitted by the at least one speaker in the main sound emission direction, in different directions for achieving a diffuse sound cloud.
