Description
Technical field
The utility model is related to the loudspeaker arrangement of car inside, especially a kind of automobile spare tire speaker of single loudspeaker.
Background technology
The loudspeaker arrangement of existing car inside, the loudspeaker being generally located on the compartment inner wall of automobile, but these loudspeaker
Acoustics cannot be satisfied the higher sound equipment requirement of music-lover, therefore to be mounted on automobile spare tire hollow there have been one kind
Active woofer on position, to improve the acoustics of car inside, to meet the higher sound equipment requirement of music-lover.
Chinese Patent No. 201320793659.8 discloses a kind of spare tyre speaker, before structure has woofer, speaker
Lid and speaker rear cover are characterized in that speaker rear cover in the basin shape shrinkage pool at spare tyre center, coincide with shrinkage pool, and solid with center
There is the circular Loudspeaker front cover of woofer to fix, also diameter and the comparable head cover of woofer sound basin mouth diameter surely,
It is connected and fixed by head cover fixed column and Loudspeaker front cover, spare tyre inner cavity top is placed on by Loudspeaker front cover frame on.Its disadvantage
It is：It is only in the basin shape shrinkage pool at spare tyre center that speaker, which is fixed, and there is no being firmly locked in spare tyre, meeting is with automobile
Traveling and pitch, cause speaker pronounce bad and poor durability；Another problem is that Loudspeaker front cover and head cover protrude from
Spare tyre top surface can interfere the lid of the spare tire cover plate in automobile boot to close.
A kind of automobile spare tire speaker disclosed in the Chinese Patent No. 201620700978.3 of the applicant's earlier application,
The spare tyre speaker being mounted in the center cavity of automobile spare tire, including shell, loudspeaker, gland and screening soundboard, the shell, gland
A vertical hole is respectively provided on soundboard with hiding, each vertical hole, which aligns, constitutes a central through-hole, and the loudspeaker are
Two or more, the outside of the central through-hole of described two above loudspeaker arrangeds in shell.Its advantage is that sharp
