Title:
AUDIO MODULE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/087904
Kind Code:
A1
Abstract:
An audio module (1) and a vehicle (10), relating to the technical field of terminals. The audio module (1) comprises a base (13), a loudspeaker (11) and a scatterer (12); both the loudspeaker (11) and the scatterer (12) are fixed to the base (13), the scatterer (12) is disposed on the sound emitting side of the loudspeaker (11), and the scatterer (12) is provided with a first inclined surface (A1) inclined towards the loudspeaker (11); along a first direction, the scatterer (12) is provided with multiple scattering slots (121) with openings located on the first inclined surface (A1), and the direction of extension of each scattering slot (121) is perpendicular to the first direction, the first direction being parallel to the base (13); the multiple scattering slots (121) each comprise a central scattering slot group (C1) and two side scattering slot groups (C2), the two side scattering slot groups (C2) being identical and being symmetrically arranged on two sides of the central scattering slot group (C1) along the first direction. The central scattering slot group (C1) corresponds to the central position of the loudspeaker (11), so that sound has better uniformity along the horizontal direction; the greatest slot depth (D1) of the scattering slots (121) in the central scattering slot group (C1) is greater than the greatest slot depths (d2, d3) of the scattering slots (121) in the side scattering slot group (C2), so that a peak-valley phenomenon in sound field frequency responses in sound can be weakened, so as to improve listening experience.
