Abstract: An axis of rotation of a rotatable connection between a rocker arm, attached to the bottom of the amplifier, and a support frame of the amplifier stand is on the centerline of the amplifier box depth. A balance spring arranged between the support frame and the rocker arm is increasing loaded with tilting back of the amplifier on the stand to oppose a fallback load of the amplifier and permit a friction device applying a frictional force dampening the relative rotation to hold the amplifier in a selected tilt angle up to 45°.

Abstract: Stereo loudspeaker in a single cabinet (CB), such as a portable stereo loudspeaker. Two dipole loudspeaker units (DLL, DLR) generate respective acoustic dipole signals (L+, L−, R+, R−) in accordance with two channels on an input signal. The two dipole loudspeaker units (DLR, DLL) are closesly spaced and oriented such in relation to each other that their respective main axes are angled (α) 70°-110°, such as 80°-100°, preferably substantially 90°, relative to each other. By placing such stereo loudspeaker in a room in front of a wall (W), reflections (RL, RR) from one side of the two dipole units' (DLL, DLR) diaphragms will reach a listener and thus serve to provide, together with the direct sound (L, R) from the opposite side of the diaphragms, a stereo image in a wide area in the room. The dual dipole arrangement enables a one-cabinet stereo loudspeaker with a narrow design. The dipole arrangement may be a two-way system with dipole tweeter units and dipole mid range units. A mono low frequency unit (WF) may be included in the cabinet (CB). The stereo loudspeaker can be configurable to either play stereo or to play mono, i.e. the dipole units (DLL, DLR) playing the same signals. Hereby the loudspeaker can play one channel while a similar loudspeaker plays another channel, thus allowing such set of loudspeakers to be used in a traditional stereo setup.

Abstract: An apparatus that provides for the reproduction of 6.1 surround sound (or other formats of) audio programs using a minimum of two speaker cluster locations is disclosed. The current invention accurately produces surround sound effects with speakers in only two locations in lieu of the conventional six. A sub-woofer, in its normal configuration, can be used with the invention if desired. The left front, rear center, rear left and center signals are produced from a left cluster array. The right front, rear center, rear right and center signals are produced from a right cluster array. This configuration eliminates the need for a center speaker and for rear speakers. Such elimination of speaker locations, along with their associated wiring, produces a less cluttered look, and lends itself to use in listening rooms of smaller size.
