DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle speaker device, and more particularly, to an in-vehicle speaker device which is mounted in a vehicle compartment to execute auxiliary sound range reproduction.

[0002]

2. Description of the Related Art Conventionally, in an on-vehicle speaker device, when one speaker (single cone) reproduces the entire band, an undesirable phenomenon in sound quality occurs due to deterioration of directivity and increase of various distortions. For this reason, conventional in-vehicle speaker devices are provided with various kinds of dedicated speakers such as low-frequency (woofer), medium-frequency (mid-range), and high-frequency (tweeter) to improve sound quality and broaden overall characteristics. It employs a compound speaker system that can be realized. here,
In particular, a low-frequency speaker (woofer) has a problem that it is difficult to secure a sufficient volume in a cabinet in a vehicle compartment having a large diameter and a small diameter, and sufficient reproduction of a low-frequency range cannot be realized.

In order to secure a sufficient volume in a cabinet for accommodating such a speaker (woofer), a conventional in-vehicle speaker device avoids a narrow arrangement space, for example, a trunk, a rear part of a vehicle compartment, a ceiling, or the like. To realize high-quality sound range reproduction. FIG.
FIG. 5 is a layout diagram showing a conventional vehicle-mounted speaker device arranged in the trunk 1b of the vehicle 1 in this manner. FIG. 8 is a layout view showing a conventional in-vehicle speaker device arranged on a carrier 1c at the rear of the passenger compartment. FIG. 9 shows a ceiling 1d in the vehicle interior.
FIG. 5 is a layout diagram showing a conventional in-vehicle speaker device arranged in a vehicle.

As shown in FIGS. 7 to 9, the conventional speaker system for a vehicle has a large-diameter speaker 50 (in order to sufficiently realize a high-quality sound range reproduction in the cabin of the vehicle 1 as described above. The woofer is disposed in various places such as a trunk 1b (see FIG. 7), a bed 1c (see FIG. 8) at the rear of the passenger compartment, and a ceiling 1d (see FIG. 9). For example, as shown in FIG. 7, a conventional on-vehicle speaker device disposed in a trunk 1b of a vehicle 1 includes a large-diameter speaker (woofer) 50 in a trunk 1b disposed in a rear portion of the vehicle 1 in a vehicle compartment. It is a built-in type that is mounted to face up, and realizes high-quality sound range reproduction by using the trunk 1b of the vehicle 1 as a cabinet.

Further, as shown in FIG. 8, in a conventional speaker system for a vehicle mounted on a carrier 1c at the rear of a passenger compartment, a speaker (woofer) 50 is housed in a box-shaped cabinet 60 having a hollow interior. It is a box type and is formed so that this cabinet 60 is fixed to the bed 1c at the rear of the vehicle 1. The conventional in-vehicle speaker device arranged on the bed 1c at the rear of the vehicle compartment can be easily attached to and detached from the vehicle compartment, so that it can be easily replaced when it breaks down.

On the other hand, the applicant of the present application has developed a conventional in-vehicle speaker device in which this cabinet is arranged on a ceiling in a vehicle cabin in order to more effectively use the cargo bed on which a box-type cabinet shown in FIG. 8 is arranged. ing. Such a conventional technique is disclosed, for example, in Japanese Patent Application Laid-Open No. 7-322379. As a conventional on-vehicle speaker device arranged on the ceiling in a vehicle cabin as described above, Japanese Utility Model Application
It is also disclosed in JP-A-7-117884, JP-A-60-108575 and the like.

[0008] As shown in FIG. 8, in a conventional vehicle-mounted speaker device arranged on a ceiling 1 d in a vehicle compartment, a speaker (woofer) 50 is housed inside a box-shaped cabinet 70. It is formed as a suspension type installed on the ceiling 1d at the rear of the vehicle 1. Such a suspended speaker system for a vehicle can use the space of the cargo bed 1c in the vehicle interior without waste, and the cabinet 70
By arranging the sound on the ceiling 1d, the output sound is reflected on the sheet and the luggage, so that a high-quality sound range can be reproduced without being adversely affected. As described above, the conventional in-vehicle speaker device includes the trunk 1b, the carrier 1c at the rear of the cabin,
A high-quality sound range reproduction has been realized by arranging a speaker (woofer) 50 having a large diameter in a vehicle cabin by effectively using an arrangement space such as a ceiling 1d.

[0008]

However, in the conventional in-vehicle speaker device, as shown in FIGS. 7 to 9, there is a limit in the arrangement space in the vehicle 1 in which the speaker 50 is arranged. Speaker 5 according to sound quality requirements
It is not possible to increase the size of the 0 aperture, increase the output of the amplifier used, and increase the number of speakers 50 mounted,
There is a problem that the installation space is reduced and the sound quality and the output sound pressure level are reduced. The present invention solves such a problem, and provides an in-vehicle speaker device that can freely set a larger speaker diameter and an increase in the number of speakers according to a demand for high-quality sound quality, thereby improving the sound quality and the output sound pressure level. The purpose is to:

[0009]
