DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker system in which a heat pipe is connected between a magnetic circuit portion of a speaker and a duct radiator. As is well known, when driving a magnetic circuit, it is recognized that high heat is generated in the voice coil and the center pole. This is because only about 1 to 2% of the power supplied from the amplifier to the speaker is diverted to acoustic energy, and the others are consumed as resistive heat loss and mechanical loss. At this time, the heat generation may reach 160 ° C., and the voice coil itself has an adverse effect on the joint with (1) 7.3 juice and corn paper, which shortens the life of the speaker. Cover up. Therefore, the allowable input must be suppressed. In particular, in a small cabinet with a small cooling space (air volume), it has been difficult to configure a speaker / stem for high output. On the other hand, there is provided a cooling system in which one end of the heat pipe is coupled to the magnetic circuit portion including the voice coil etc. and the other end is coupled to the heat pipe disposed outside the cabinet. However, a speaker / stem having a sufficiently large allowable input can be obtained. FIG. 1 is a schematic side view showing such a conventional speaker / stem cooling system. Reference numeral 1 is a cabinet, 2 is a speaker, 3 is a duct radiator, and a heat as shown in FIG. 2 is provided between the magnetic circuit portion (usually upper / lower = central hole of ball) of the speaker 2 and the duct radiator 3. Pipe 4 is connected. According to this, the heat of the magnetic circuit portion is transmitted to the duct radiator (2) V 3 through the heat pipe 4, and the heat is dissipated to the outside. Therefore, cooling of the magnetic circuit is performed 13-05-2019 1 efficiently. By the way, the connection between the duct radiator 3 and the heat pipe 4 has to be in close contact in order to make the heat conduction efficient, and a strong integration is made. Therefore, conventionally, as shown in FIGS. 2 and 3, one end of the aluminum pipe 8 is inserted into the inner rib goo attached to the outer ring 6 constituting the duct radiator 3 via the rib 6, and this insertion is performed A jig was inserted into the rear aluminum pipe 8 to expand the aluminum pipe 8 and perform an integration operation so as to be crimped to the inner ring-. 1. A heat exchange medium such as freon is injected into the aluminum pipe 8 and the end of the expanded aluminum pipe 8 is squeezed and sealed to obtain the heat pipe 4. However, in such a conventional cooling system, it is extremely difficult to combine the dogutra / eta 3 and the aluminum pipe 8 and, further, a cooling medium is injected into the aluminum pipe 8 before such a coupling is carried out. In order to form 4, the operations of the injection (3 and the abovementioned drawing processing etc. were troublesome. The present invention ameliorates the problems of the prior art, and therefore, the object of the present invention is to interpose the completed heat rope into the mounting hook integrally provided on the duct radiator and An object of the present invention is to provide a loudspeaker system which is integrally connected to the duct runner by caulking and which is simple and easy to obtain. Hereinafter, an embodiment of a speaker stem according to the present invention will be specifically described with reference to the drawings. FIGS. 4 and 5 are a perspective view showing one embodiment thereof and a side view with a part thereof cut away. A rectangular duct runner 9 has four through holes 10, and a binding member 12 having a notch 11 is integrally provided at the center of the lower surface thereof. In addition, the binding member 12 is integrally and simultaneously obtained at the time of molding such as extrusion and drawing of the duct radiator 9. As materials for these materials, aluminum (4) and other metals having thermal conductivity and alloys thereof are used. Reference numeral 13 denotes a heat pipe as a finished product, one end of which is inserted into the binding member 12, and the binding member 12 is crimped by a jig so that the heat pipe 13 closely contacts the binding member Combined. FIG. 6 shows another embodiment, in which a substantially Y-shaped binding member 15 is integrally provided on the lower surface of a duct radiator 14 similar to the duct runner 9 described above. The binding member 16 is the holding object 16α. 15h is receded straight down, and a fine locking ridge 16 is provided on its inner surface. One end of the heat pipe 17 is interposed between the clamping pieces 15a and 15h from below, and the heat pipe 17 is ducted by caulking the heat pipe 17 with the clamping pieces 15α and 16b using a predetermined jig. Integrally coupled to the radiator 14. In this embodiment, since the contact resistance at the time of bonding is large and the contact area is increased at the mutually intrusive portions, the thermal conductivity between the heat pipes 17 and the duct run (5) ator 14 is further increased. Increase. FIG. 7 shows another embodiment. This is what made the duct lager 18 circular. A binding member 19 similar to that shown in FIG. 4 is integrally provided at the lower portion of the duct radiator 18 and the heat vibrator 20 is coupled to the binding member 19 in the same manner as described above. Even if it is such, it is easy to combine. Thus, as can be seen from the 13-05-2019 2 embodiment shown in FIGS. 4 to 7, the heat circuit 13.17.20 with high thermal conductivity and the magnetic circuit portion (such as a ten-ter-pole) of the speaker and duct radiators 9, 14.18. Can directly transfer the heat generated when the voice coil or center ball operates to the duct radiator, so that the heat dissipation efficiency of the magnetic circuit portion can be increased, and the allowable input of the speaker can be increased. . In addition, the duct radiators 9 and 14 ° 18 are self-cooled by the inflowing air drawn to the internal pressure generated by the vibration of the woofer (6), and the above-mentioned heat radiation action becomes even more effective. In summary, according to the present invention, one end of the heat pipe is coupled to the magnetic circuit portion of the speaker, and the other end of the heat pipe is crimped to the mounting hook integrally provided on the duct radiator. Practical-F is more advantageous because the bonding is simple and reliable, mass production is possible, and the heat exchange characteristics between these are as good as before b. 13-05-2019 3
