Abstract: An electronic component, such as a speaker, is supported on the chassis of an electronic device, such as a small radio pager, by a resilient annular member which is latched to the chassis. The annular member has an inner surface for receiving a part of the component, such as the speaker pot, and a plurality of fingers extending from the member and inserted through an opening in the chassis with outwardly extending hook-like ends which engage the opposite side of the chassis. The member and fingers are flexible for mounting on the chassis, and are rendered more rigid when the component is inserted therein so that the fingers hold the member on the chassis. The annular member may include portions which are flexed when the component is placed therein to store energy which tends to move the component out of the member. When used for supporting a speaker, the member tends to move the speaker pot to hold the speaker edge against a grill which may be formed in the housing of the device.

Abstract: A loudspeaker grille made of stiff material such as stiffened grille cloth, has at least a major proportion of the length of its edge so shaped that, when seen in cross section, one part extends rearwardly, approximately perpendicularly to the plane of the grille, and another part returns forwardly again from the rear edge of the first part and at an acute angle to the first part so as to present a free edge lying to the rear of the plane of the grille and outwardly of the first part. Both parts of the edge portion, when seen in cross section, may be straight and define a generally V-shaped configuration of which the included angle may be between 30 degrees and 45 degrees prior to fitting the grille in position in a loudspeaker. The edge portion is then held in a groove in the housing of a loudspeaker as a result of the resilience of the edge portion.

An adjustable deflector is positioned near the tweeter. Another embodiment of the invention has only a woofer and a tweeter on only one corner panel with the crossover network arranged to energize the two in a common frequency range that is greater than an octave.

Abstract: Method and apparatus are disclosed for reducing undesired transmission of acoustic energy from a loudspeaker cabinet into the structure of a building in which the loudspeaker is located, and also for reducing the undesired acoustical feedback from the loudspeaker into the turntable assembly. A high-Q resonant external suspension apparatus is positioned beneath the cabinet of the turntable or the cabinet of the loudspeaker. This suspension apparatus includes compression springs having a predetermined taper and a very high-Q which are arranged to provide resonance in all three directions (X, Y and Z axes). The mass of the supported structure and the spring constant of the tapered springs are proportioned to provide a resonant frequency in the range from approximately 3 to 6.5 Hertz with approximately 4 Hertz being shown as the presently preferred value.

Abstract: A loudspeaker enclosure for housing a basic speaker and providing a conduit for channeling the sound waves emitted from the back surface of the basic speaker so that the sound waves are shifted in phase and emerge from a port in the enclosure and add to, rather than acoustically cancel, the sound waves emitted from the front surface of the basic speaker. The sound waves from the back surface of the speaker travel through the length of the conduit which is folded through several 45.degree. angles upon itself. These sound waves are directed through the conduit by striking and reflecting from a plurality of at least six reflector panels which are mounted at 45.degree. angles. In this manner, due to the nature of reflections at 45.degree. angles, each portion of a sound wave impulse travels the same distance as each other portion and the impulse emerges from the port basically intact. The enclosure has a unique shape because of the several foldings of the conduit through 45.degree. angles.

Abstract: An acoustic speaker enclosure of sufficiently thin design that it may be suspended from a wall and then concealed by a framed picture being hung thereover. Forwardly directed sound from the speaker radiates transversely through 360.degree. through a first passage defined in the enclosure. Rearwardly directed sound from the speaker is transmitted to the resonator frame through a second free transverse passage as well as a baffled third passage. A rearwardly disposed resonance board of the speaker enclosure is in abutting contact with the wall, and rearwardly sound from the enclosure is transmitted through this resonance board to the wall to resonate the latter to radiate sound to the room in which the speaker enclosure is disposed. Due to the multiplicity of sources of sound from the acoustic disclosure, a hearer in a room is not cognisant of the location thereof, particularly when the enclosure is concealed by a framed picture.
