PURPOSE:To vary both the voice in direction and the voice in volume, by inserting the virtually square deflected wing substance in which several deflected wings inclined in the vertical direction are arranged into the display part in 8 combinations. CONSTITUTION:The deflected wing substance 5' to be stored into the hole provided on the upper case 1 is inserted to the voice part 5, and the speaker 6 functioning as the voice generating source is provided at the lower part of the substance 5'. The substance 5' has the framework 5c both the vertical and horizontal widths of which are l along with several deflected wings 5a having a large angle of inclination each arranged equidistantly. Furthermore, several altered wings 5b having a small angle of inclination are distributed in the direction orthogonal to the wings 5a. Such substance 5' has nearly a square form having the length l of a side, thus obtaining 8 different ways for the aural output in the upper case 1. As a result, both the direction and volume of the voice is varied. |
