Abstract

PURPOSE:To display rationally a function of holding parcels and a function of a speaker, by dividing a rear parcel shelf into a front-side member for holding parcels and a rear-side member for installing a vibration plate for the speaker, and by arranging these two members separately from each other. CONSTITUTION:A rear parcel shelf 5 is formed of a front-side member 6 and a rear-side member 7 divided from each other, and thses two members 6 and 7 are fitted to a car body separately from each other so that vibrations are not transmitted between them. The front-side member 6 is formed to have a tray-shaped holding part 6a whereon parcels 8 are placed. The rear-side member 7 is provided in part with a vibration plate 9 for a speaker, and this vibration plate 9 is supported by a reinforce 11 arradnged in the direction of the width of a car, through the intermediary of a buffer member 10. Moreover, the vibration plate 9 is made to be an elastic body, supporting a vibrating driver 12 for sounding in the central part thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rear parcel shelf structure for a vehicle, and more particularly to a rear parcel shelf structure for a vehicle that reasonably functions as a place for placing objects and as a speaker.

In conventional rubber cell shelves with full acoustic equipment, ordinary speaker units equipped with diaphragms made of paper cones or the like are used either as a single full-range type or in combination as a multi-way type. These completed lettuce bee crab knits were either buried in a predetermined position on the rear parcel shelf or housed in a speaker box placed on the rear parcel shelf. However, if you try to sufficiently reproduce the low frequency range with a structure in which a normal speaker unit made of cone paper or the like is embedded in a rear cell shelf, it is necessary to use a speaker unit with a large diameter, so it is difficult to use several positions. Restrictions arise, resulting in the inconvenience of not being able to effectively secure space for storing small items and the like. Furthermore, when a large speaker containing a large-diameter speaker unit is placed on the rear parcel gel foot, there is an inconvenience that the rear visibility is obstructed. In order to resolve this inconvenience, the applicant first made various panel members such as plywood, iron plates, or synthetic resin plates used in various parts of the vehicle, such as the rear parcel shelf, hold an acoustic vibration driver. We have proposed a vehicle acoustic device in which the panel member itself is used as a diaphragm. According to this, a sufficient vibration area can be obtained without occupying space in the vehicle interior, so that low frequency reproduction comparable to that of a large-diameter speaker is possible.

However, if the top plate of the steering compartment shelf is used as a diaphragm, if a small baggage is placed on top of it, the sound effect may be hindered by the small baggage, or vibrations may be caused when the body comes into contact with the diaphragm. This may cause discomfort and discomfort.

The present invention has been made in view of these conventional problems.In addition, the rear parcel shelf is divided into a front side member and a rear side member, which are spaced apart from each other, and a small article placement section is formed on this front side member. death.

In addition, by disposing a speaker diaphragm holding an acoustic excitation driver in a part of the rear member, it can rationally perform the function of placing objects and the function of a speaker, especially a woofer. Its purpose is to solve the above problems.

Below, this invention will be explained based on the drawings.

1 to 4 are views showing one embodiment of the present invention.

In the diagram, 1 is a hatchback type vehicle, 2 is a back door,
3 is the rear seat, 4 is the luggage room, and 5 is the rear parcel shelf. This eleventh parcel shelf 5 is formed by being divided into a front side member 6 and a rear side member 7, which are attached to the vehicle body at a distance from each other so as to prevent transmission of husband and wife vibrations. The front member 6 is formed with a tray-shaped placing portion 6a on which the small baggage 8 is placed. The reason for the tray shape is to allow the passenger to clearly see where the parcel 8 is placed, and also to prevent the parcel 8 from slipping and moving toward the rear member I while driving. This is to prevent this.

A diaphragm 9 for a speaker is provided in a part of the rear side member 7. This diaphragm 9 is supported by a reinforcement 11 arranged in the vehicle width direction via a buffer member 10 made of rubber, urethane, or the like. The nuclear diaphragm 9 is made of an elastic body, and has an acoustic vibration driver 12 in its center, and is excited by the vibration driver 12 to generate sound. In this embodiment, the diaphragm 9 generates a monaural bass range,
Tweeters 13 (only one shown) having right and left medium and high frequency ranges are disposed on both sides of the rear member 70 in the vehicle width direction, so as to perform sound reproduction using a so-called 3D stereo system. By incorporating such a sound device, most of the rear member I will vibrate, but this part has a small distance from the back door 25 and is originally a part where small items 8 etc. are not placed. Moreover, since it is a part that is rarely touched by hands, vibrations of the parcel 8 and discomfort caused by human body contact hardly pose a problem. The rear member 1 is rotatable via a hinge 14, making it easy to take luggage 15 into and out of the rug room 4. Further, 16 is a thin skin material.

As explained above, according to the present invention, with the above structure, it is possible to easily secure a large effective vibration area equivalent to that of a complete large-diameter woofer using only the rear side member, thereby improving bass reproduction. Designing becomes easier. In addition, since the front member is formed with a small article storage area, it is clearly visible that this is the area where small items, etc. should be placed, and since it is located on the front side, small items may be placed on the rear member by mistake. There is no risk of objects placed on the front member being placed on the front member, and objects placed on the front member will not slide sideways onto the rear member, so the baggage may resonate and emit abnormal noises, or the acoustic effect may be impaired. Good sound reproduction can be expected without any distortion. Furthermore, since the front member is arranged at a distance t2 from the rear member, it does not vibrate, and there is also the effect that the body will not feel uncomfortable even if it touches it.
