この考案は小型で、且つ低音増強に多大の効果
を有する車載用スピーカーシステムのキヤビネツ
ト構造に関する。[Detailed Description of the Invention] This invention relates to a cabinet structure for a vehicle-mounted speaker system that is compact and has a great effect on bass enhancement.

孔のみを穿設したものでもよい。 Figures 1a and b show Example 1, with at least 1
In a speaker system having more than one speaker unit 6a, 6b (the figure shows a two-way type speaker unit, one each for bass and treble), a groove 2 is provided on the back surface of the cabinet 1, and the groove 2 is A duct 3 for phase inversion is opened at the bottom. Further, a reflective plate 4 is provided to cover the groove 2.
By installing the duct 3, sound paths 5, 5' leading from the duct 3 to both sides of the cabinet 1 are formed. In the speaker system having the above-mentioned configuration, since it is a phase inversion type, the bass range limit is expanded compared to a closed type system, and the sound paths 5 and 5' act as an acoustic load, that is, a backroad horn for the bass sound coming from the duct 3. Therefore, the acoustic radiation efficiency becomes very high, and it has a great effect on bass reinforcement. Furthermore, since the duct 3 is located on the back side, the front side of the cabinet 1 can be effectively used for installing the speaker unit. By making the groove 2 widen from the opening of the duct 3 toward both sides of the cabinet, the effect as a backroad horn can be further enhanced. Further, the duct 3 may be one in which only a sound emitting hole is bored to provide a duct function.

徴を有する。 FIG. 2 shows a second embodiment, in which the reflector 4 is made of a hard material, and the reflector 4 is attached to the cabinet 1 via a buffering material 7 made of a soft material such as urethane foam to simultaneously enhance bass sound. It has the feature of acting as a protector for the rear window.

である。 As a third embodiment of the present invention (drawings omitted), the back surface of the cabinet 1 is curved along the rear window, and the cabinet 1 is installed in contact with the rear window surface to form sound communication between the groove and the window surface. This allows the reflection plate to be omitted.

では期待できない効果を有するものである。 As described above, the in-vehicle speaker system devised in this application has the above-mentioned configuration, expands the low frequency reproduction limit as a phase inversion type, and furthermore produces a backroad horn effect by utilizing the sound path formed on the back of the cabinet to transmit the bass from the duct. It has an effect that cannot be expected with conventional speaker systems in that it has an extremely excellent low-frequency radiation effect.
