摘要： In a speaker system, the rearward area of a diaphragm is separated into two acoustic regions. One of the two acoustic regions is a rear opening type and the other is a base-reflex type. An acoustic mass, such as a port or a passive radiator, is located between the first and second acoustic regions for providing a phase inversion characteristic.

摘要： A speaker system which has a speaker unit with a diaphragm and an acoustic path provided on the front side of the diaphragm so as to guide sound waves emitted from the diaphragm. The acoustic path is defined by a sound absorbing member. The space in the acoustic path and the sound absorbing member is separated by a partition member which is disposed in such a manner that at least a portion of the sound absorbing member is exposed to the space in the acoustic path, except that the portion of the sound absorbing member just adjacent the diaphragm is not exposed to the acoustic path. This arrangement eliminates peaks and troughs of resonance determined by the length of the acoustic path, so that flat sound pressure frequency characteristics can be obtained over a wide range up to high-pitch tone region.

摘要： A speaker and the like, which is capable of wideband reproduction by improving the bass characteristic, and which is suitable for size reduction, is provided.A housing (110) includes one main surface (111) having a polygonal shape, and an opening portion (112) in the one main surface. A diaphragm (120) is disposed in the opening portion so as to cover the one main surface, except for corner regions (115a, 115b, 115c, and 115d) which are areas in the vicinity of respective vertices of a polygonal shape of the one main surface. A driving unit (130) causes the diaphragm to vibrate so as to generate a sound corresponding to a signal inputted from an outside. A plurality of movable supports (140a, 140b, 140c, and 140d) is disposed in the respective corner regions, for supporting the diaphragm by joining the housing and the diaphragm such that the diaphragm is vibratable.

摘要： A speaker system according to the present invention comprises a cabinet (10), a speaker unit (11), a first parting board (12), a drone cone (13), an adsorption member (14), a second parting board (15), a backboard (16), a variable mechanism (17), and a port (18). A sound pressure generated by the speaker unit (11) causes a pressure variation in a second chamber (R12) via the drone cone (13). The adsorption member (14) with an effect of physical adsorption is operable to suppress the pressure variation. Furthermore, by displacing the diaphragm (171), the variable mechanism (17) is operable to reduce a pressure variation of a direct current component, which is caused by variations in ambient temperature or atmospheric pressure of the speaker system.
