Patent number: 9326084Abstract: A one-cabinet stereo loudspeaker, wherein at least first and second loudspeaker units (LL, LR) are arranged in a cabinet structure (CB) so as to radiate sound with at least three lobes of the first acoustic signal (L) alternating with respect to horizontal angle with at least three lobes of the second acoustic signal (R). This provides a spacious sound experience at all locations around the loudspeaker.Type: GrantFiled: June 25, 2012Date of Patent: April 26, 2016Assignee: Libratone A/SInventor: Jes Mosgaard

Publication number: 20130336504Abstract: 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 (?) 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.Type: ApplicationFiled: June 7, 2010Publication date: December 19, 2013Applicant: LIBRATONE A/SInventor: Jes Mosgaard

Publication number: 20130101146Abstract: Loudspeaker in a single cabinet arranged for wall mounting. The loudspeaker has two dipole loudspeaker units spaced apart and arranged to generate respective acoustic dipole signals. Reflectors, such as plane surfaces, are arranged to reflect sound from the respective dipole loudspeaker units. The reflectors and the dipole loudspeaker units are arranged such in relation to the cabinet that sound from one side of their diaphragms is directed substantially parallel with the wall and away from the cabinet, preferably to the sides. Sound from the opposite side of the diaphragms is directed substantially perpendicular to the wall and away from the wall. Such loudspeaker is suited in versions as a stereo sound bar, e.g. placed under a flat screen TV set. The loudspeaker provides a wide stereo image which can be experienced in a large area in a normal room due to reflections from side walls, and still the loudspeaker produced a stable centre image.Type: ApplicationFiled: June 7, 2010Publication date: April 25, 2013Applicant: LIBRATONE A/SInventor: Jes Mosgaard
