Second horn component, 19 ..... dustproof net. DETAILED DESCRIPTION OF THE INVENTION The present invention relates, for example, to the improvement of a composite type speaker in which a horn and a weeter portion are coaxially incorporated in a woofer portion. In the prior art, for example, a combined sneaker horn and a driver fist unit incorporated into a bone tweeter woo and a driver fist unit are separated, and most of the horn fist tweeter have ikora sensu-in the horn 4114, and The dustproof device in the compound horn steerer of fine stone A was shown in FIG. 1 and FIG. The driver shown in Fig. 1 is 1 driver t22! A dustproof net -9 'formed of natural fiber or synthetic resin W only is stretched over i of j3 and equalizer 14 at @ 4, and the one shown in Fig. Y2 is protected at the opening of horn 15 I put paste l19 '˜ ˜. By the way, since the horn / tweeter part B shown in FIG. 1 stretches the protection net 19 'in the gap of 1iI11 or less between the equalizer 14 and the diaphragm 13, the variation of the frequency characteristic-1 becomes large and the sound quality changes. It is easy to make the pickup plate 13 and the net 19 'contact and a squeaky sound is generated easily. · And the diaphragm 19' is set in a small area between the horn and tweeter B and the pickup plate 13 It took a hand [-1] to stretch. Further, since the dustproof net 19 ′ ′ is stretched at the opening of the horn 15 as shown in FIG. 2, the # length and sharpness peculiar to the horn 15 are lost, giving a serious adverse effect on the lock-in. was there. The present invention has been made in view of the above-described points, and the purpose of the present invention is to make the soil of the horn / tweeter the first horn 1 of the driver unit side and the tenth of the grill 1111. The dustproof net can be installed in a simple and easy manner between the first horn machine and the second horn component by being divided into two parts and 01-05-2019 1 assembled freely with a mass bite, thus the frequency characteristic And providing a composite type speaker capable of exerting a dustproof function while minimizing an adverse effect on sound and electric power. The following is an example of one reconsideration of this paper according to 3 3 (Y: Is a woo-city formed by incorporating a 7-ton fist-toe-ta part B coaxially in the inside thereof, and this woo-ha i7. The tweet screw 1J attached to the lower surface of the cone-shaped diaphragm 1 is inserted into the magnetic cap 3 & of the magnetic circuit 3 and the diaphragm 1 is an outer peripheral stage of the frame 4 captured on the upper surface of the magnetic circuit 3 The backing 6 is pressed to the portion 41L via the edge 5 and the plate 1 is fixed, and the joint portion of the * 1111 and 7 * chair coil hinge 2 is fixed to the frame 4 by using the tumbler material T and 11-(formed. On the other hand, in the horn tweeter part B, the magnetic circuit 9 is fitted in the concave portion 8 of the mounting member 8 screwed on the upper surface of the magnetic circuit 3 of U .. The voice coil portion 12 having the moving plate 1 and supported by the supporting member 11 by the damper 10 is inserted into the hole 9a of the magnetic circuit 9 and disposed on the upper portion of the moving plate 13. The six pieces 15 having the equalizer 14 are fixed to the front pt support member 11 using several screws 16 and the grill 1T integrally formed with the horn 15 is fixed to the upper surface of the backing 6 Thus, the upper surface of the ・ ·· part B is stacked on the grill 1T. The horn 15 can be assembled on the first horn component 15 of the driver unit 18 on the side of the driver unit 18 with the upper surface of the pad plate 6 pressing the diaphragm 1 of the woofer capital B to the outer cylinder step g4a of the frame 4 and its upper surface And the second horn component 15B integrally formed with the grille 1T. The outside 11117m of the grill i7 is bonded to the flange 4b of the frame 4 of the woofer A, or fixed by means such as screwing. A dustproof net 19 is attached to the first horn component 15m and the 1st 82nd horn iff child 15B 1) 1), and this dustproof net 19 is a natural fiber or synthetic resin peak and is acclaimed t1 first 1 @ 2-FN- groove groove member 15 B is adhered to a 15 mm groove member with a seeding agent and assembled. When assembled, the outer peripheral edge portion is attached to a single layer. The 1 μ grouper 11 of the present embodiment is composed of the above-described N. Oki formation, and is divided into two parts of a 41 earth component 15 and a second horn component 15 B. And the outer peripheral edge portion of the dustproof net 19 is bonded between the first horn component 15A and the second horn component 15B of the second 15 The dustproof net is formed at a slight interval between the moving plate 13 and the equalizer 14 of the driver unit 18 as in the conventional composite type loudspeaker shown in FIG. You do not have to put 19 on it. Therefore) back net 19? The horn 15 can be squeezed and treated as an orchid, and the variation of the wave number characteristics is small, and the sound and the characteristic of the horn and the speaker are precisely detected without tingling of the sound '5'. Not lost. In the uninvention, as described above, the horn of the horn / tweeter part can be assembled by being divided into two parts, the first horn component of the driver unit y) lIl, ll and the second dimension component on the grill side. The dustproof net is stretched by simple handling between the first horn component and the second horn 01-05-2019 2 component so that the first horn component and the second horn component can be assembled in two minutes. Therefore, compared with the conventional product in which the 5: Fi dust net is installed in the gap of IIIIl or less between the equalizer and the diaphragm, it is possible to minimize the adverse effect on the frequency 4 and 8 and the sound quality and reduce the dustproof effect. . 4, a brief explanation of the surface Figure 1 The figure of the person in the past is also a half sectional view showing an example of the speaker, and the diagram 2 is the 101st figure <the other figure of the conventional combined type sneaker>; FIG. 3 is a half sectional view showing an embodiment of the combined loudspeaker according to the present invention.
