Title: Driving method of piezoelectric speaker
Inventor: TAKAYA TADASHI
IPC: B06B1/02
Filed: 1983-02-08
Abstract: PURPOSE:To attain mellow sound by inserting a resistance in series with a piezoelectric speaker and driving the piezoelectric speaker via the resistance to decrease a sound pressure level at a high frequency and to suppress remarkably the peak of harmonics especially. CONSTITUTION:A driving circuit 3 is conneced across the speaker 1 via the series resistance 2. The speaker 1 is driven by a voltage dividing a signal from the drive circuit 3 by the impednace ratio of the series resistance 2 and the impedance of the speaker 1. In taking an unnecessary frequency as >=4kHz and the impedance value of the speaker at 4kHz as 250 ohms, then the resistance 2 having the resistance value of nearly 250 ohms is connected. In this case, the sound pressure-frequency characteristic is as shown in (a). The final resistance value is acutually set while comparing the sound pressure-frequency characteristic obtained by inserting the resistance 2 with the desired frequency characteristic. When the resistance value is decreased, the characteristic is shown in (b) and when the resistance value is increased conversely, the characteristic is shown in (c). The characteristic (d) is the case that no resistance 2 is connected.

Abstract: PROBLEM TO BE SOLVED: To make it possible to ignore a leakage between subdivisions and increase the flow rate of a fluid to enhance the conversion/recovery performance by providing an active region including a continuous flow path with flow path parts joined to each other with each of restricted parts and positioning each of manifold holes at each of terminal parts in the continuous flow path. SOLUTION: A flowing solution for feeding a fluid finds its way into the active region of a gasket through a manifold hole 21 and an aperture P1. The active region is provided with three flow path parts 26, 28, 30 connected in series so as to form a curved flow path. The flow path parts 26, 28, 30 are positioned adjacent to each other and are connected to each other with flow restricted parts 36, 38. Each of the restricted parts 36, 38 is narrower in width than each of the flow path parts 26, 28, 30, so that the velocity of the fluid increases when it passes through each of the restricted parts 36, 38. This signifies that the fluid pours accompanied with a violent turbulent flow which churns the fluid held in the following flow path part, into this flow path part.  Further, the treated solution comes out through an aperture P2 and a manifold 23 after circulating via the continuously connected flow path parts 26, 28, 30.
