Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a gasket for a composite speaker.

(Prior Art) Conventionally, for example, in a composite type speaker including a relatively large-diameter bass speaker and a relatively small-diameter treble speaker, as shown in FIG. A structure is known in which a holder 24 for a treble speaker 23 is attached to the treble speaker 23, and the treble speaker 23 is coaxially mounted via the holder 24 in the inner space of a substantially conical diaphragm 25 of a bass speaker 21. There is. In the figure, 26 indicates a plate, 27 a magnet, 28 a frame, 29 a gasket, and 30 a voice coil. Although not shown in the drawings, there is also a system in which a treble speaker is integrally attached to an inner frame of a bass speaker by screwing or the like.

However, in any case, special holders or screws are required to attach the treble speaker, which increases the number of parts and increases costs, and the mounting structure of the treble speaker is generally complicated and difficult to assemble. The drawback was that the work was complicated.

The present invention has been proposed to overcome the above-mentioned drawbacks.

(Purpose of the invention) The purpose of the invention is to integrally form the gasket body of the bass speaker and the housing case of the treble or mid-range speaker, so that the mounting parts for the treble- or mid-range speaker can be installed separately. To provide a composite type speaker gasket which can be used as the gasket body of a bass speaker without the need for a gasket, thereby reducing the number of parts, reducing costs, and simplifying the mounting structure.

(Structure of the idea) The present invention will be explained below with reference to the drawings.

1 and 2 show a first embodiment of the present invention, and in the figures, reference numeral 1 indicates a well-known cone-shaped bass speaker with a relatively large diameter, and its approximately conical vibration A high-pitched speaker 3 such as a piezoelectric or electrodynamic tweeter is disposed in the internal space surrounded by the plate 2. The diaphragm 2 of the low-tone speaker 1 is formed into a substantially circular shape when viewed from above, and a gasket body 5 made of synthetic resin is fixed onto the outer peripheral edge 4 of the diaphragm 2. A plurality of support arms 7 extend from opposing long sides 6 of the gasket body 5 toward the center of the gasket body 5, and have their tips located above the center of the diaphragm 2. As shown, the annular gasket body 8 of the treble speaker 3 is integrally connected. A substantially conical diaphragm 9 is disposed inside the gasket body 8, and a substantially cylindrical storage case 1 with a bottom is provided below the gasket body 8.
0 is integrally attached. This storage case 10 is a component of the high-pitched speaker 3, that is,
In the case of a piezoelectric type, it is used to house a piezoelectric element, etc., and in the case of an electrodynamic type, it is used to house a voice coil, a magnet, etc. (none of which are shown).

In addition, in FIGS. 1 and 2, 11 is the magnet of the bass speaker 1, 12 is the same plate,
The reference numeral 13 also indicates a frame, the reference numeral 14 indicates mounting holes drilled at the four corners of the frame 13, and the reference numeral 15 indicates a mounting plate.

The first embodiment described above is a case in which the present invention is applied to a so-called two-way composite speaker consisting of a bass speaker 1 and a treble speaker 3, but the second embodiment shown in FIG. The present invention is also applicable to a three-way type composite speaker equipped with three speakers for bass, treble, and medium sounds, as in the embodiment. That is, in this embodiment, in order to arrange the treble speaker 3 and the mid-range speaker 16 in the internal space surrounded by the diaphragm 2 of the bass speaker 1, the inner side of the gasket body 5a of the bass speaker 1 is Two gasket bodies 8a, 8b are separately disposed in the body, and these are integrally connected to the gasket body 5a of the bass speaker 1 by support arms 7a, 7b. On the back side of gasket body 8b, there is a storage case (not shown) for storing the components of each speaker 3, 16 as described above.
8b and are attached integrally with each other.

In this embodiment as well, it goes without saying that the drive type of the medium-tone speaker 16 and the high-tone speaker 3 may be an electric type, an electrostatic type, or the like.

Next, FIGS. 4 and 5 show third and fourth embodiments, respectively, in which mounting holes 17 are bored in the four corners of the gasket body 5b or 5c of the bass speaker 1, and on the other hand, The four corners of the frame 13a or 13b corresponding to the mounting hole 17 are cut out and the gasket body 5b or 5c is attached to the backing plate 15a.
It can be attached to a predetermined attachment point by screwing or the like.

In the third embodiment (see Fig. 4), a locking piece 18 is attached to the upper edge of the frame 13a and the frame 13a is attached to the gasket body 5b by bending the locking piece 18, or the frame 13a and the gasket body 5b are fixed together using a suitable adhesive, and in the fourth embodiment (see Fig. 5), a plurality of projections 19 are provided vertically on the side edge of the gasket body 5c, and these projections 19 are fixed by thermal caulking through holes in the upper edge of the frame 13. Even in these embodiments, the treble or midrange speaker can be attached integrally with the woofer 1 by the gasket of the present invention.

(Effects of the invention) As described above, according to the invention, in a composite speaker including a bass speaker and a treble or midrange speaker, the gasket body of the bass speaker and the treble or midrange speaker are housed. Since the case and the case are integrally formed, this type of speaker can be installed together with a bass speaker without the need for holders or screws for attaching high- or mid-range speakers, reducing the number of parts. This has the effect of reducing costs. In addition, compared to the conventional mounting structure for high-pitched speakers, etc.,
It is extremely simple and has the advantage of simplifying manufacturing and assembly operations.
