In the figure, (21H is the speaker unit), (21H is a cabinet in which this speaker unit is airtightly attached to the panfer board (2a), and +31 is an interior in which the inside of this cabinet (2) is communicated with the outside through its communication hole (38). The bass reflex port has been added to the above panful plate (7a) with IIC passing through.

壁に残されたその時の開口により。Conventional phase-inverting speaker devices are configured as described above to extend the bass range, but there is an inconvenience in terms of use in that the interrelationships between the speaker unit, cabinet, and bass reflex port are fixed. According to the invention, the bass reflex port is covered with a sound-absorbing material so as to leave a desired opening in the peripheral wall, and the opening left in the peripheral wall is used.

Although the bass reflex port is shielded by a sound absorbing material (4), the presence of the opening (3b) in the peripheral wall of the bass reflex port allows the desired bass range to be obtained as a semi-sealed type.

キャビネットの裏板であっても良い。In the above embodiment, as shown in FIG. 2 (8), there are completely large openings (3) in two places on the inner peripheral wall of the bass reflex port (3).
b), but this opening may be formed by a plurality of protruding supports (3c) K as shown in Fig. 2 (bl), or alternatively, it may be formed by a separate part (3d) as shown in Fig. 2 (cl). )
Alternatively, the bass reflex port may be fixed to the front end surface of the bass reflex port, or the bass reflex port may be fixed to the panful plate (28) or the back plate of the cabinet.

単に得られるという効果がある。The speaker device of the present invention is configured as described above, and can be installed in a cabinet by leaving an opening with a desired opening area on the peripheral wall of the bass reflex port and simply covering the entire bass reflex port with a sound absorbing material. The effect is that it is extremely easy to obtain semi-enclosed bass characteristics suitable for interior speaker units.
