DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker having an integral structure of a diaphragm and a screw bin, and more particularly to an improvement of a vibration system of the speaker. 1 // a-//? 62 In the prior art, this type of loudspeaker has been shown in FIGS. In FIG. 1, reference symbol l & denotes a diaphragm having a diaphragm 2a, a bin 3a and a support member (edge) 4 & in an integral structure, and 5 is a chair coil wound around the l bin 3b. In FIG. 2, lb is a diaphragm with a diaphragm 2b and a bin 3bJJi integral structure, 4b is a support member fixed with a diaphragm 2bK adhesive 6, and 5 is a chair coil wound around the bin 3b. In FIG. 3, 1c is a diaphragm in which the diaphragm 2c and the mevin 3c are fixed by separate members, 4c is a support member fixed to the upper portion of the bobbin 3c by the adhesive 6, and 5 is a bin 3c. It is coiled, but it is a chair coil. The same applies to the operation principle of the first to third sections, and the support members 4m, 4b and 4e are fixed to the magnetic circuit or frame and the coil 5 is positioned in the gap of the magnetic circuit. The diaphragm 1m + 1b of FIGS. 1 and 2 is formed in a dome shape, and the rise of the dome-shaped diaphragm is wound with a 3m-bin bottle and a 3bK mace startle 1 coil 63 coil 5 There is. The diaphragm 2c in FIG. 3 also has a dome shape, but the chair coil 5 is wound in an lbin 3c. The support members "+ 4b, 4c" are designed to act as mere stiffness, for example, they are shaped like corrugations, which were structurally perforated. Sound emission is designed to be performed by the central dome shaped diaphragm. Since the conventional speaker is 11-05-2019 1 configured as described above, there is a disadvantage that the bobbin is thin and the strength is weak. Therefore, the driving force generated by the chair coil causes distortion in the pg bin and is easily deformed, and the lossless driving force transmission which is the original purpose is not performed, and the voice coil is caused due to the Mevin deformation. And abnormal noise, and the transient response is degraded due to internal loss. The present invention is a rounding which eliminates the above-mentioned disadvantages of the conventional ones, and prevents the deformation of the bobbin by the existing 3) 64 by attaching a reinforcing pin integral with the support member to the bottle. It is an object of the present invention to provide a speaker which transmits a lossless driving force and is free from the contact of a chair coil and the generation of abnormal sound. Hereinafter, an embodiment of the present invention will be described with reference to FIG. Various embodiments are shown in FIG. 4 to tiA 7. In FIG. 4, 1 m is a diaphragm of the diaphragm 2 & integral with the bobbin 3 a, and 7 a is a bin of reinforcement with the supporting member 8 a. It is mounted on the outside of the existing bobbin 3a. In this reinforcement bobbin 7a? The chair coil 5 is wound. In FIG. 5, lb is a diaphragm having an integral structure of the diaphragm 2b and the mevin 3b, and 7b is a reinforcing bobbin having an integral structure with the support member 8b, and the existing one is mounted inside the bin 3b. The voice coil 5 is wound around the existing bobbin 3b. In FIG. 6, IC is a diaphragm in which the diaphragm 2C and a part of the bin 3C are integrally formed, 7C is a reinforcement of an integral structure with the support member 8C, and the reinforcing bobbin 7C is outside the existing partial bobbin 3C. It is attached to. Then, I added, Kei 965 pin 7cK chair coil 5 is wound. In FIG. 7, ld is a diaphragm having an integral structure of a diaphragm 2d and an I-bin 3d, 7d is a reinforcement of an integral structure with a support member 8d, and a reinforcing zabin 7d is long over the entire inner surface of the bin 3d. It is stretched and mounted. The existing coil coil 5 is wound around the outside of the bin 3d. In FIGS. 4, 5 and 7, the supporting member is disposed below the coil 5, but in FIG. 6, the supporting member is disposed above the voice coil. The speaker according to the present invention configured as described above has high rigidity due to the reinforcement of the integral structure with the support member mounted on the existing bobbin and the thickness of the entire bobbin being increased. Etc. can be prevented. That is, the contact and abnormal noise of the voice coil due to the deformation of the bobbin are reduced, and the internal loss is small and the deterioration of the transient response is kept low to enable the transmission of the lossless driving force which is the purpose of the bin. For example, the level-frequency characteristics of the speaker according to the present invention and the conventional speaker are shown in FIG. 8 by their respective 6G solid lines and broken lines, but according to the present invention, the extreme peak dip due to l-bin division vulgaris suppressed Also, it can be seen that the frequency at which the peak dip occurs can be moved to a high frequency. Although the dome-shaped speaker has been described in the embodiment of the present invention, the same function as described above can be obtained even in the case of other--brid type or cone type speaker. As described above, according to this 11-05-2019 2 invention, the reinforcement of the support member and the integral structure is attached to the existing bobbin portion, and the thickness of the l-bin is increased by preventing the deformation of the bobbin. It is possible to obtain a high-quality, high-performance speaker without deterioration of transient response, and the effect of being able to obtain no driving force and prevent the occurrence of contact of a voice coil and abnormal noise. 11-05-2019 3
