DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker
apparatus having a speaker apparatus K of 1% drone cone 4 eve as well as a bass reflex type with
a hat. Conventionally, in the speaker device 17, as shown in FIG. 1, the bass speaker 3 is attached
to the puff full 2 on the front face of the cabinet 1 and the port 4 is provided to form a portless
busless speaker device. The equivalent circuit of this speaker device is as shown in FIG. 2t. As
shown in FIG. 2K, in the case of Ktk 211, ie, 211, F is a driving force + KM is an electrical
resistance, and RMg is a speaker mechanical resistance. MM is the speaker support system mass,
CM is the compliance of the speaker support system 2-RA is the radiation resistance 1M ^ is the
radiation mass, liMB is the cabinet, the flow resistance of the cabinet is CMK is the compliance of
the cabinet-RAPF1 * '-)) @ Village @ p, 9 qi ill in MMP boat, R wing t is the island in the flowpressure resistance in the boat. Also, as shown in Fig. 3 for the speaker # # i as another speaker,
the bass m speaker 3 and the parzo bra Jie J 8 are mounted on the par fle 112 to the cabinet as
shown in FIG. . The equivalent circuit of this speaker storage is as shown in FIG. In this case, the
only difference from the case of water supply is that the RAM is a passive radiator No. Fence anti
+ RMII is a passive mechanical pile of passive rage I. b. The mass of 1M wing of the passive
ladder is collected by the compliance of the support system of the CMI Fipa and the cibrageta of
the passive radiator. In this way (Two islands of boat bass reflex type and drone cone type
speakers 11 are in the same way that their equivalent circuit aIk, respectively-a medical
examination of which one is better, one is mourning, the other is qr After all, it is difficult to
make judgment number 3 difficult 4 After all, be sure to select the method sent to the re-testing
sound field and the reproduction program. There was no such thing as it was not possible to get
warm iM low-pass sound quality to one play 8 ラ or now raw progella ^. The present invention 喰
4! Island with +6 things. The following one invention is a drawing 61 of one embodiment! 1 to 7
will be described with reference to FIG. A cabinet 6 has a bass speaker 8 attacked by a forward
buff full plate 7 of the cabinet 6 and a boat 9 in public hall H. This port 9 is for sheet metal press
molding and-**** ingestion 5! Semi-made by shape, #!
The 7 holes 11 for attaching the NK pa and the Syndaciaator 0 are integrally provided, and the
screw holes 12 are real number @ noodles in the 7 runes 11. If it is k according to composition
type and @ 81 I5, it will be a passless type speaker device with a water boat. Island 4 And, fixed
to the above-mentioned baffle plate 7 is a passive radiator on the 7-round part 11 part of the
nine-boat 9. When the mounting screw 14 is screwed into the screw hole 12 through the gasket
13, the speaker device of 10 drop-on shown in FIG. As described above, by freely attaching and
detaching the passive radiator to the boat, it is possible to make a port-equipped bass reflex 4
eve island or a drone cone type according to the playback program during playback sound field,
and an optimum low frequency range It is possible to make a sound purchase, and the function
as a speaker device has been increased), which is of great practical value.
