PURPOSE:To form the mechanical filter only with the mechanical oscillators featuring the same oscillation type and same material along with the easy manufacture by securing the connection for both the main connector and the overreach connector nearly vertical to the mechanical oscillator. CONSTITUTION:Mechanical oscillators 17 and 18 featuring the primary oscillation in the twist oscillation type and mechanical oscillator 19 performing the secondary oscillation in also the twist oscillation type are distributed so that the directions of the longer axes may be parallel virtually to each other. And the control is given to secure the virtual conicidence between the primary resonance frequency of oscillators 17 and 18 and the secondary resonance frequency of oscillator 19. Then main connector 20 which performs the vertical oscillation to give connection of the same phase among oscillators 17, 18 and 19 plus overreach connector 21 which performs the vertical oscillation to give connection of the opposite phase to oscillators 17 and 19 are connected almost vertically to oscillators 17, 18 and 19. |
