摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a diaphragm for an electroacoustic transducer for which the first and the second paper layers are uniform and excellent in quality and appearance, etc., and bonding fibers are not mixed in a wood pulp dispersion liquid, and to provide a manufacturing device of the diaphragm.
SOLUTION: A first paper making apparatus 5 with a first paper making tub 3 provided with a first paper making net 1 and a second paper making apparatus 5A with a second paper making net 7a freely movable to a prescribed position and a second paper making tub 8 disposed at a fixed position are provided. The first paper layer 6 is formed by the first paper making apparatus 5, the first paper layer 6 is moved to the lower part of the second paper making tub 8 and inverted while it is kept sucked to the second paper making net 7a positioned on the side of the first paper making tub (3) by pressure reduction, and the wood pulp dispersion liquid 9a for the second paper layer is poured into the second paper making tub 8. The second paper layer 12 is made by the pressure reduction while keeping the first paper layer 6 sucked, the pulp dispersion liquid 9a is discharge to the lower part, and thus the second paper layer 12 is deposited to the first paper layer 6.

摘要： PROBLEM TO BE SOLVED: To solve the problem that the control of periodic vibration in a short side direction is insufficient, the divided vibration of a (0, 4) mode cannot be suppressed and high-pass reproduction equal to or higher than a frequency in which the divided vibration of the (0, 4) mode is generated cannot be performed in a conventional structure of two-line arrangement where four driving points and eight driving points in total in each line of two lines in parallel with a long side, in a flat diaphragm speaker which performs the multi-point driving of a rectangle diaphragm by a plurality of electrodynamic drivers.
SOLUTION: The flat diaphragm speaker is constituted so that the divided vibration in an order lower than a (6, 4) mode is suppressed by making the three-line arrangement of 3-2-3 by arranging three, two, and three driving points on each line of three lines in parallel with the long side of the rectangle diaphragm and a frequency band higher than that in a conventional art can be reproduced by simple structure without increasing the driving points more than necessary.

摘要翻译：解决的问题为了解决短边方向的周期性振动的控制不足的问题，不能抑制（0,4）模式的分频振动，高通复制等于或高于产生（0,4）模式的分频振动的频率不能在两行布置的常规结构中执行，其中两行的每行中的四个驱动点和八个驱动点总共平行于长在平面隔膜扬声器中，通过多个电动驱动器执行矩形隔膜的多点驱动。解决方案：平板振动板扬声器构成为通过使三相，二相和三极三通排列，通过使3-2-3的三线排列来抑制低于（6,4）模式的分压振动可以通过简单的结构再现与矩形膜片的长边平行的三行的三行驱动点，并且可以通过简单的结构再现比现有技术更高的频带，而不需要增加驱动点。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a surround playback device for providing a playback sound having less sense of incongruity, even when a listener leaves a sweet spot. SOLUTION: The surround playback device includes buffers 3, 4 for passing through respectively received stereo L and R signals; an adder 5 that extracts a difference signal S3 between signals S1, S2 wherein the signal S1 is a positive input and the signal S2 is a negative input; a high-pass filter 6 which makes the difference signal S3 input signal ; a low-pass filter 7 for receiving an output signal S4 of the high-pass filter 6; and a low-pass filter 8 for receiving the difference signal S3, and the surround playback device is configured, such that a signal S7 obtained by summating an output signal S5 of the low-pass filter 7 and an output signal S6 of the low-pass filter 8 by an adder 9 is added to the signal S1 at an adder 10 to obtain an L side surround signal S9, and the signal S7 is given to an inverter 11 that inverts the signal S7 at a gain 1, an output signal S8 of the inverter 11 is added to the signal S2 at an adder 12, to obtain an R-sdie surround signal S10.
