Abstract: An electric musical instrument includes a body having a front side and a rear side, a plurality of strings extending across at least a portion of the front side of the body, and at least one electric pickup to detect vibrations of the strings and generate a pickup signal. The instrument includes at least one speaker mounted at the rear side of the body, in which the speaker includes an acoustic driver and an acoustic deflector. The acoustic deflector is configured to receive acoustic energy propagating from the acoustic driver and deflect at least a portion of the acoustic energy. The instrument includes an amplifier to amplify the pickup signal to generate an amplified pickup signal, and drive the at least one speaker based on the amplified pickup signal.

Abstract: An electric musical instrument includes a body and a resonant stack. The resonant stack includes a bridge having a bridge mass and at least a first spring having a first spring constant, in which the first spring is positioned between the bridge and the body. The resonant stack has at least one resonant frequency that is dependent on the bridge mass and the first spring constant. The electric musical instrument includes a plurality of strings that extend across at least a portion of the body, in which each string has a vibrating length defined at least in part by the bridge. The electric musical instrument includes at least a first pickup device to detect vibrations of the strings and generate a first pickup signal, and at least a second pickup device to detect movements of the bridge and generate a second pickup signal.

Abstract: An open audio device with a housing that is configured to be worn on the torso and an acoustic transducer carried by the housing, the acoustic transducer configured to either radiate sound outwardly of the housing or convert received sound into an electrical signal. A structure is coupled to the housing. The structure is proximate to the acoustic transducer. The structure is constructed and arranged to inhibit radiated sound or received sound from being interrupted by a flexible sheet material, such as clothing, located over the housing.

Abstract: The technology described in this document can be embodied in a method that includes receiving, at a processing device, a feedback signal from a recording device, and generating, based on the feedback signal, a control signal for adjusting an acoustic output of a speaker device to achieve a target acoustic distribution within the environment. The feedback signal can indicate an acoustic characteristic of an environment in which a speaker device is located. The method also includes providing the control signal to the speaker device.

Abstract: An acoustic device includes an enclosure defining an internal cavity. A first passive radiator arrangement including a first passive radiator diaphragm is arranged along a first side of the internal cavity and a second passive radiator diaphragm arranged along a second, opposite side. The first passive radiator arrangement is mounted such that the first passive radiator diaphragm and the second passive radiator diaphragm can vibrate relative to the enclosure, and the first and second passive radiator diaphragms are coupled together such that there is substantially no relative movement therebetween. A second passive radiator arrangement includes a third passive radiator diaphragm. The second passive radiator arrangement is mounted such that the third passive radiator diaphragm can vibrate relative to the enclosure. An active electro-acoustic transducer arranged to radiate acoustic energy into the internal cavity and thereby excite vibration of the first, second, and third passive radiator diaphragms.

Abstract: An acoustic device with a housing with a central portion and first and second leg portions that depend from the central portion, a first acoustic driver carried by the first leg portion, a second acoustic driver carried by the second leg portion, and an audio signal control system that directs audio signals to each of the first and second drivers, where the drivers transduce the audio signals to output sounds. The audio signal control system is arranged to apply first and second equalization modes to the audio signals in a first and second listening mode, respectively. The second equalization de-emphasizes frequencies below a first threshold frequency and boosts frequencies above the first threshold frequency.
