In recent automobiles, the thickness of doors has tended to increase, and the thickness has been diversified. Depending on the model, door trims (door interior panels) have been provided with places (storage sections) for placing drink bottles and cans, for example. There are also car models. Therefore, a door having a large distance between a door trim and an inner sheet metal which constitutes a door is particularly thick. Some doors are relatively thin. In addition, there are various types of door inner sheet metal, such as flat ones and those that are curved in order to increase mechanical strength.

Those who provide speed to respond to the diversification of speaker mounting had to design and manufacture speakers of the appropriate shape and size for each vehicle model. Specifically, for example, as shown in FIGS. 7A to 7C, speaker units a 1 and a 2 which are changed for each vehicle type are designed and manufactured, and these are respectively held by holders, that is, brackets bl and b. They were attached to b2 and b3, and each was attached to the car door. More specifically, FIG. 7A shows a vehicle model in which the distance between the door trim and the inner metal plate is relatively small, that is, the door has a small thickness and the shape of the inner metal plate mounting portion is flat. Corresponding, and therefore the speaker unit a1 The length is short, the length of the bracket b1 is relatively short, and the shape of the end face that is in contact with the inner sheet metal at the rear of the bracket b1 is flat.

The one shown in FIG. 7B is for a vehicle type in which the door is relatively thin and the shape of the mounting portion of the inner metal plate is not flat but curved, and accordingly, the length of the speaker unit a 1 is small. It is short, the length of the bracket b2 is short, and the shape of the rear end of the bracket b1 is curved according to the shape of the mounting portion of the inner sheet metal on the door side.

The one shown in Fig. 7C is for vehicles where the distance between the door trim and the inner metal plate is large and the shape of the mounting portion of the inner metal plate is flat. Therefore, the length of the bracket b3 is relatively long, and the shape of the rear end of the bracket b3 is flat.

FIGS. 7A to 7C are only some examples, and it may be necessary to change the length of the bracket or complicate the shape of the rear end.

By the way, designing and manufacturing the speed corresponding to each type of vehicle is a major factor that hinders the reduction of the manufacturing cost that is strongly required for vehicle door speakers. This was a major factor in lowering the price required for the equipment.

The present invention has been made to solve such a problem, and a vehicle door speaker mounting device and mounting that can be installed at a low price in response to differences in thickness, shape, and the like of a vehicle door to which speed power is mounted.
