The invention provides a bass loudspeaker for an automobile, which comprises a loudspeaker body, a cone and a sound cavity box, and is characterized in that the loudspeaker body is arranged in the cone; the cone is arranged on a top plate of the sound cavity box; an inner cavity of the sound cavity box is a sound cavity body; the volume of the sound cavity body is larger than that of an inner cavity of the cone; the inner cavity of the cone is communicated with the sound cavity body; the sound cavity box is positioned on the back surface of the loudspeaker body; the sound cavity box is provided with a vent hole communicated with the sound cavity body; and the sound cavity box is further provided with an installation part used for being connected with a car door metal plate. The sound cavity box is arranged below the cone and located on the back face of the loudspeaker body, compared with a cavity in a car door, a sound cavity body of the sound cavity box has better sealing performance, and meanwhile the size of the sound cavity body can be flexibly set according to needs, therefore, the low-frequency sensitivity and the low-frequency sound effect of the bass loudspeaker can be effectively improved by utilizing the sound cavity body.

    本发明提供了一种用于汽车的低音扬声器,其包括扬声器本体、音盆、音腔盒,所述扬声器本体设置在所述音盆中,所述音盆设置在所述音腔盒的顶板上;所述音腔盒的内腔为音腔腔体,所述音腔腔体的体积大于所述音盆的内腔的体积,所述音盆的内腔与所述音腔腔体相通;所述音腔盒位于所述扬声器本体的背面;所述音腔盒上设置有与所述音腔腔体相通的通气孔,所述音腔盒上还设置有用于与车门钣金相连的安装部。本发明将音腔盒设置在音盆的下方并位于扬声器本体的背面,与车门内的空腔相比,音腔盒的音腔腔体具有更好的密封性,同时音腔腔体的尺寸可以根据需要进行灵活设置,从而利用音腔腔体能够有效地提升低音扬声器的低频灵敏度和低频音效。
