    摘要: A diaphragm for loudspeakers comprises chitin as a natural high polymeric material having a large value of Young's modulus and kraft pulp having large mechanical internal loss. Therefore, the deformation and the partial vibrations of the diaphragm during diaphragm operation do not come out due to the use of the chitin, because the flexural rigidity of the diaphragm is considerably large. Mechanical internal loss is also large owing to the use of the kraft pulp. As a result, it is possible to obtain a loudspeaker which has little fluctuation in frequency response, and which provides a superior sound pressure-frequency response, a superior distortion factor and a superior phase response.

    摘要: An electrodynamic loudspeaker which comprises a generally rectangular flat vibrating plate, and first and second magnetic drives for driving the vibrating plate to produce vibrations. The first magnetic drive is so positioned as to drive the vibrating plate at a first location corresponding to one of two line nodes m.sub.1 and m.sub.2 of vibration of a first predetermined frequency f.sub.1 which would be produced when the vibrating plate is driven at the center thereof, whereas the second magnetic drive is so positioned as to drive the vibrating plate at a second location corresponding to one of four line nodes n.sub.1, n.sub.2, n.sub.3 and n.sub.4 of vibration of a second predetermined frequency f.sub.3 which would be produced when the vibrating plate is driven at the center thereof. Each of all of the line nodes extends in parallel to the shorter sides of the rectangular shape of the vibrating plate.

The LCD 20 is operable to perform a predetermined operation in response to an electrical signal applied thereto. A space 24 for sound emission is formed between the case 22 and the LCD 20. The electromechanical acoustic transducer 23 is connected to the case 22, and emits sound to the space 24. If the electromechanical acoustic transducer 23 emits the sound to the space 24, energy of the emitted sound causes the LCD 20 to vibrate and thereby to externally output the sound.
