Reference numeral 10 denotes a door speaker device, which is a door inner panel 1a of a front door 1 of the automobile.
A speaker box 12 is attached to the back of a speaker body 11 whose four corners are screwed to the inside of the vehicle. The size of this speaker box is the door inner panel 1a.
Also, the glass space 2 is set so that the glass 2 can be moved up and down behind in the door space 3 between the door outer panel 1c. On the side surface 12a on the door hinge side of the speaker box 12,
An elliptic cylindrical portion 13 having an opening 13a at its side end and having a cross-sectional area that does not attenuate the low range is provided in a protruding manner.

取ることが容易になる。An opening 28 is formed on the bottom surface of the cowl side 20 and the corresponding upper surface of the rocker 7 so that the space of the cowl side 20 communicates with the space of the rocker 7. A partition wall 25 is formed above the cowl side 20. However, this partition wall may be omitted in the structure in which there is no hole of a size that affects the acoustic characteristics in the portion that follows the partition wall. When the door is closed, both seal rings 15 and 23 (FIG. 3) are in close contact with each other, so that the speaker box 12 is placed in the inner space of the cowl side 20 and the opening 13a,
Securely connect through 9 and 21. As a result, the volume of the speaker box 12 is increased by the volume of the cowl side 20, and a substantially sufficient enclosure is obtained. Therefore, the deterioration of the bass range is avoided, and the door trim 4 located around the speaker body 11 and the vinyl cover around the speaker body 11 are not exposed to the back pressure, and the resonance phenomenon is avoided. Even if the sound image is localized in the low range to the high range in the front and the low-range speaker is provided in the rear, it becomes easy to balance the front and rear.

On the other hand, when the capacity including the rocker 7 and the cowl side 20 is 28 liters according to the present invention, the effective resonance frequency is 78 Hz. Further, it has been confirmed that the bass range can be extended by about 3 Hz by adding a bass reflex port in which the inner diameter of the cylindrical portion 27a is set to be equal to or about 1/2 of the speaker aperture.

に延ばすことができる。According to the present invention, even if a speaker dedicated to the low frequency range is not separately prepared, the space inside the speaker box communicates with the space inside the cowl side when the door is closed. The enclosure capacity of the box is expanded, and deterioration of the low-frequency acoustic characteristics of the speaker is prevented. Since the speaker box type is premised, back pressure is not generated in the door, and resonance of peripheral parts such as the door trim and the vinyl cover is eliminated. Further, by providing a bass reflex port on the cowl side, the bass range can be further extended.
