果が得られない。[Detailed description of the invention] In an electronic organ having one Leslie effect unit, when obtaining the Leslie effect using the upper and lower keys, in order to increase the effect, the normal sound generation circuit and the Leslie sound effect generation circuit are combined. I try to make one sound louder than the other. For example, when trying to obtain the Leslie (tremolo or chorus) effect,
Generally, the sound is emitted only from the Leslie sound effect generating circuit, and no sound is emitted from the normal sound generating circuit. Therefore, if you try to stop the Leslie effect for both the upper and lower keys, the signal will be cut off at the same time and the sound will instantly change to the normal sound, so the rotation of the Leslie effect motor will gradually slow down and the effect will be delayed until it stops. I can't get it.

素子２Ａ，２′Ａの制御極に接続する。 1 and 1' are musical tone signal passing circuits connected to a tone circuit, an upper keyboard circuit, and a lower keyboard circuit (not shown), respectively, and both branch into normal sound generation circuits 1A, 1'A and Leslie sound effect generation circuits 1B, 1'B. are doing. The normal sound generation circuits 1A, 1'A and the Leslie sound effect generation circuits 1B, 1'B are composed of switching elements 2A, 2'A, 2B, 2'B, amplifiers 5, 5' shared by the upper and lower keys, and It consists of speakers 6 and 6'.
The switching elements 2A, 2'A, 2B, 2'B are field effect transistors, and the switching elements 2 are interposed in the Leslie sound effect generating circuits 1B, 1'B.
The control poles of B and 2'B are connected to the power supply via time constant circuits 3 and 3' and Leslie effect switches 7 and 7' for the upper and lower keys, and are connected to the power supply through resistors R 1 and R 2 and capacitors.
The time constant circuits 3, 3' consisting of C 1 and C 2 control switching elements 2A, 2'A which are inserted into the normal sound generating circuits 1A, 1'A via circuits 4, 4' consisting of inverters, for example. Connect to the pole.

６′に至り、レスリー効果音が放出される。 Now, when the Leslie effect switches 7 and 7' are closed, a positive voltage is applied to the control poles of the switching elements 2B and 2'B.
B, 2'B turn on, switching element 2
A and 2'A are turned off because a negative voltage is applied to their control poles, and the musical tone signals from the upper and lower keys pass through switching elements 2B and 2'B and reach the speaker 6', and the Leslie sound effect is produced. released.

るまでのレスリー効果を出すことができる。 Next, when the Leslie effect switches 7 and 7' are opened, the switching elements 2B and 2 are turned off until the charges accumulated in the capacitors C1 and C2 are discharged according to the time constant of the time constant circuits 3 and 3'. 'B turns on and then turns off, and at the same time switching elements 2A and 2'A turn on. Thus, if the time constants of the time constant circuits 3 and 3' are set to match the rotation stop time of the Leslie effect motor that drives the fan 8, the speaker 6' can be operated by the Leslie effect motor when the power is turned off. You can create a Leslie effect that gradually slows down until it stops.

For 2'B, in addition to a field effect transistor, an element having the same function such as a photo coupler can be used. As described above, the present invention has the effect that even if the Leslie effect switch is turned off, the Leslie effect motor gradually slows down until it stops producing the Leslie effect sound.
