Problems solved by technology

However, when the woofer is working, it can emit bass in the direction opposite to the direction in which the sound propagates into the cabin, and these counter-directional bass can cancel the bass transmitted into the cabin, thus weakening the bass sound effect of the HIFI speaker

Embodiment Construction

[0029] The making and using of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0030] In this specification, directional expressions such as "up", "down", "bottom", "top", and "side" are all defined according to the direction of the vehicle when it is running normally.

[0031] As an example, the embodiments described below relate to mounting a HIFI speaker unit on a rear shelf of a vehicle (such as Figure 8 and Figure 9 Cavity brackets on rear shelf 7) shown. But this is not limitative, the cavity bracket according to the present invention can be used to install the HIFI speaker unit in other places required in the vehicle (such as on the C-pillar). Also, as an example, as in figure 2 As shown, the speaker unit includes a woofer 61 and a tweeter 62 to ensure the overall sound effe...

Abstract

The invention relates to a cavity bracket for a vehicle loudspeaker unit. The loudspeaker unit comprises a woofer (61) and a tweeter (62) and is fixed to a vehicle body by means of the cavity bracket, the cavity bracket comprises a first bracket half part (1) and a second bracket half part (2), the first bracket half part (1) and the second bracket half part (2) are correspondingly provided with cavities and a plurality of connecting flanges, and the corresponding connecting flanges are assembled together to form a cavity for accommodating the woofer (61), wherein a woofer mounting hole is formed in the cavity wall of the cavity of the first bracket half part (1), and the first bracket half part (1) comprises a tweeter mounting part adjacent to the woofer mounting hole and located outside the cavity. The invention further relates to a vehicle comprising the cavity bracket. According to the cavity bracket, the diffusion of the bass in the opposite direction can be prevented, and the bass sound of a HIFI speaker unit is effectively improved.

Description

technical field [0001] The present invention generally relates to the field of components for vehicles, and more particularly, to a cavity bracket for a vehicle speaker unit, and to a vehicle including such a cavity bracket. Background technique [0002] The speaker unit is an extremely important part of the vehicle audio system, and the sound quality of the speaker unit has a direct impact on the quality of the vehicle user's sense of hearing. Due to the particularity of the vehicle, in order to ensure good sound quality, the number of speakers in some high-end vehicles can generally reach six to ten or more, and they can be distributed in different positions such as the dashboard, front and rear doors, and rear shelves to achieve Professional-grade HIFI (High Fidelity, high fidelity) effect. [0003] These loudspeaker units are usually mounted on the vehicle body by means of special loudspeaker brackets. figure 1 is a schematic diagram of a speaker bracket 100 according ...
