摘要： A speaker which is thin but which is capable of providing high-fidelity reproduction and ensuring a suitable level of sound pressure even when it is brought close to a wall. A closed chamber is formed behind one part of a disphragm mounted in an enclosure, and an open chamber is formed behind another part of the diaphragm. At least one voice coil driver unit is connected to the diaphragm. The phase difference between sounds radiated from the front and rear surfaces of the diaphragm is increased as large as possible by using an acoustic duct for the sound radiated through the open chamber, thereby minimizing cancellation of sounds and improving the sound pressure level.

摘要： A speaker system has an acoustic diaphragm and an image projection screen provided on a surface of the diaphragm integrally therewith so as to enable the user to enjoy both realistic image on the screen and powerful sound reproduced through the diaphragm. The rear surface of the diaphragm is closed at a peripheral portion thereof while the central portion of the rear surface of the diaphragm is opened to the exterior, so that the speaker system can provide a high level of reproduced sound pressure in low-pitched region, while the thickness of the speaker is reduced remarkably. The diaphgram can be driven by a plurality of driving units so that the speaker system can operate only with an ordinary stereophonic amplifier. The diaphragm can be composed of a pair of diaphragm elements capable of vibrating independently of each other and the screen may be integrally and commonly attached to the surfaces of these diaphragm elements in such a manner as to allow the diaphragm elements to vibrate independently of each other, whereby the speaker system can operate in stereophonic mode. Any variation in the acoustic characteristic attributable to variation in the condition of installation is compensated for by a change in the ratio of the opened area of the rear surface of the diaphragm to the whole effective vibration area or by a selective provision of a sound absorbing member on the rear side of the cabinet.

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： A multi-layer block to be developed into a disk having a honeycomb construction is initially developed into a columnar block, and then the bottom of the columnar block is radially developed for obtaining a core of a speaker diaphragm. A suitable circular thin layer is attached to the top and bottom of the core to complete a diaphragm. The columnar block may be developed by means of a cone-shaped tool into a truncated cone, and this truncated cone may be further developed into a flat disk by applying a force to the top thereof. Since the forces on development are applied to the block uniformly, the density of hexagonal sections of the honeycomb construction is uniform throughout the entire circumference of the core providing superior speaker characteristics.

摘要： A digital signal represents a desired amplitude frequency characteristic. A desired transmission characteristic is derived from the desired amplitude frequency characteristic. A sound signal is processed in accordance with the desired transmission characteristic. The processed sound signal is converted by a speaker into corresponding sound. The process of the sound signal corrects and compensates for the original sound pressure frequency characteristic of the speaker and thereby actualizes the desired amplitude frequency characteristic.
