Detailed Description of the Invention The present invention relates to a speaker fL provided with an immunity stop @ junction 1. As shown in FIG. 2A, a low resonance frequency f. The sound pressure characteristics are adversely affected by the fact that the deep pit 1 occurs at the point 1 and the admittance decreases even in the region 4 and the characteristic becomes extremely uneven. Therefore, an impedance circuit is connected to the non-committee # 4 Heuss coil of the speaker to flatten the admittance characteristics as viewed from the input side of the speaker, and to solve the above-mentioned problems. In the following, the figure # will be illuminated by one real m? Denoting lJ, in FIG. 1, reference numeral 1 denotes a speaker, which is connected to an impedance circuit in which a resistor R is connected in series to a parallel circuit of a capacitor C and a coil L in the tzh row to its voice coil. This impedant 11g circuit is for the purpose of sensitizing the admittance property of the second bad a EndPage: 1 or the song 1III which can be dropped in the low range by the coil L component! The admittance characteristic of b 'c 4 N cont / The G component makes it possible to obtain the admittance 脣 a of the song l 1 lild in the region. In this case, it is determined by the value of curve 9's song 9's L coil L! +, Ill sparse (! Determined by #ll of capacitor C, both curves, the level v4 low at one end of d is determined by the value of resistance R. And select the value of vCl capacitor C1 coil LX starvation R so that the curve maim island level and the lowest level 'D path 1 + 4 (D rehe Qfca i Z, ilJkallml), (1 is -kj The admittance% seen from the input end 2, 2 'is a common 1l II connection, L = 2. 25 飄 H 1 G = 3 μF, R = 40 when the input end 2.2' to 7! It is a 7-order attance characteristic. From this, it can be seen that the lower band, ^ (235r4) is flattened to a large scale compared to one song 1Illla. Further, it is the admittance characteristic viewed from the input 07-05-2019 1 end 2, 2 'when the curve g company L = 2.0 mJO = 3 μF, R = 80. This Ω is becoming more complete. From the above, according to the present invention, the admittance characteristics of the entire speaker can be flattened and made possible. 4 Quick description # 1: Figure 1 is a circuit diagram of an embodiment of the present invention, and Figure 2 is a custom-made diagram of atomicity. 出 願 Applicant Pioneer Corporation Company Dan) 4EndPage: 2 07-05-2019 2
