| The aim of the invention is to produce a sound generator for eliminating interference by means of sound absorption and for reproducing signals, speech and music. The sound is preferably generated by means of micro- and nanomechanical air pumps (12) whose output flow is controlled by the actuator (16) according to the required sound signal and exits via a sound channel (11); the complementary channel (11') acting on a closed buffer volume (15). As with conventional loudspeaker enclosures, the function of the buffer volume (15) is to make an acoustic monopole radiator out of the ineffective dipole of the sound channel (11) and the channel (11'). In the case of air pumps (12) with high pressure ratios, the necessary buffer volume is correspondingly small. The sound-generating volume flow is measured in the sound channel (11) by means of a micromechanical flowmeter (18) and can be readjusted according to a comparison of the desired value and the actual value. Finally, a bore (19) with a high flow resistance balances out air pressure fluctuations and drift errors in the buffer volume (15). | ||||||

| (57)【要約】 本発明の目的は、吸音手段を用いて干渉をなくすための、及び、信号、スピーチ及び音楽を再生するための音響発生器を生成することである。 出力流れは、要求される音響信号に基づいてアクチュエータ（１６）によって制御され音響通路（１１）を経由して出ていき、補助通路（１１'）が閉じられた緩衝容積（１５）に作用する、微小及び極微小メカニカルエアポンプ（１２）によって好適に音響が生成される。 従来型のラウドスピーカのエンクロージャと同様に、緩衝容積（１５）の機能は、音響通路（１１）と通路（１１'）の無効な双極の範囲外に音響単極を作ることである。 圧力差が大きいエアポンプ（１２）の場合、それに応じて必要な緩衝容積は小さい。 音響発生器の容積流は、音響通路（１１）において、微小メカニカル流量計（１８）によって測定され、要求値と実測値との比較に基づいて再調整できる。 最終的に、流れ抵抗が大きい孔（１９）が緩衝容積中の空気圧力の変動とドリフトエラーとを平均化する。 | ||||||

| PURPOSE: To control a thermal energy flow, and to control the shape, temperature distribution, pressure, density, and conductivity of plasma by adding heated gas. CONSTITUTION: Gas is heated by I 2R loss in a metallic supply duct connected with a step-down transformer which supplies currents with a low voltage and the large number of amperes. The distribution to discharge of the flow of the heated gas is made excellent. A cathode surrounds this hanging edge, and forms a discharge space with an anode isolated from this. Gas or mixed gas to be used changes, for example, the adhesion and reconnection balance of ion/ electrons so that the gas or mixed gas to be used can be added to discharge. The adhering speed linearly depends on the number and density of electrons. The largest main adhesive element is air, and it moves to reconnection control so that discharge stability can be improved, current density can be increased, and electron generating efficiency can be improved. Thus, the shape, temperature distribution, pressure, density, and conductivity of plasma can be controlled. COPYRIGHT: (C)1990,JPO | ||||||

| The invention presented here refers to a pneumatically driven loudspeaker, comprising at least one first chamber (1, 62) having higher pressure than the surroundings and with at least one first opening (8, 61) to the surroundings. The loudspeaker in addition comprises a second chamber (2, 64) with lower pressure than the surroundings and with at least one second opening (9, 63) to the surroundings. The first and the second openings can by means of valve mechanisms (3, 65, 91, 92) alternately open and close at a selected frequency, resulting in pressure fluctuations which give rise to sound of the desired frequency. The loudspeaker according to the invention can be used in hi-fi applications as well as in active noise suppression in jet engines, in ventilation systems, in gas turbine outlets and in exhaust systems in combustion engines. | ||||||
