Abstract: Bass reflex type loudspeaker enclosure comprising a cabinet, a loudspeaker and a first vent. The acoustic loudspeaker enclosure further comprises a second vent and an internal heat sink which is located inside the cabinet and intended to be thermally coupled to an electrical component in order to dissipate, inside the cabinet, heat produced by the electrical component, the first vent, the second vent and the internal heat sink being positioned so that an air flow which flows through the first vent, the second vent and into the cabinet moves the heat produced by the electrical component out of the cabinet.

Abstract: According to the invention, the sound playing wood (1) includes a wood (2), a leg (3) and equipment inside the wood (2). The wood (2) is set on the leg (3), and a hole (12) is made at the bottom and inside the wood. The equipment includes an amplifier (4) and a computer (5), which are attached to the inner surface of the hole (12) inside the wood (2). The equipment also includes a transducer (6) attached to the inner surface of the wood (2) to make the wood (2) vibrate. By vibrating the wood (2) with the transducer (6), the wood is made to resonate and reproduce sound.

Abstract: Embodiments of the invention include an acoustic transducer device having a base structure that is positioned in proximity to a cavity of an organic substrate, a piezoelectric material in contact with a first electrode of the base structure, and a second electrode in contact with the piezoelectric material. In one example, for a transmit mode, a voltage signal is applied between the first and second electrodes and this causes a stress in the piezoelectric material which causes a stack that is formed with the first electrode, the piezoelectric material, and the second electrode to vibrate and hence the base structure to vibrate and generate acoustic waves.

Abstract: A portable speaker system for an electric string instrument such as a guitar. The portable speaker system has a housing including an audio jack for receiving a raw audio signal from a guitar, an amplifier, a speaker, and a power supply. The portable speaker system attaches to the guitar by a button connector which releasably attaches to a strap button of the guitar, and a stabilizer for inhibiting rotation of the portable speaker system when attached to the guitar. The portable speaker system portably generates output sound from the raw audio signal. The portable speaker system can couple with a portable computing device, which can process the raw audio signal and provide a supplementary audio signal, from which the portable speaker system can portably generate output sound.

Abstract: A loudspeaker includes a bottom plate, an internal magnet, an internal plate, an external magnetic part, a frame, a diaphragm, and a voice coil. The internal plate includes a cutout portion so that the internal plate is smaller than the internal magnet when viewed from the top surface of the internal plate. Between the voice coil and the internal plate, there are a holding portion holding magnetic fluid and a void part having a void. The magnetic fluid is held in part of the cutout portion.

Abstract: Speaker protection may be based on multiple speaker models with oversight logic that controls the speaker protection based on the multiple speaker models. At least one of the speaker models may be based on a speaker excursion determined from feedback information from the speaker, such as a current or voltage measured at the speaker. Excursion based on the speaker feedback may be used to determine an error in an excursion prediction made from the audio signal. The excursion prediction may then be compensated for that error. In some embodiments, a direct displacement estimate of excursion generated from speaker monitor signals is used to correct a fixed excursion model applied to an input audio signal.

Abstract: Embodiments are provided for an improved peripheral speaker. The peripheral speaker includes an exterior casing enclosing one or more drivers. The exterior casing further has a channel formed therein such that the channel is sized to removably secure an electronic device. The exterior casing is equipped with a connector lead which partially defines the cavity and that connects the one or more drivers to a port of the electronic device. The one or more drivers output audio according to an audio signal transmitted from the electronic device via the connector lead.

Abstract: A compact, battery-powered, pocket-sized recording studio with headphones to offer consumers—in a device about the size of a smartphone—a means of recording, editing, mixing, and transferring their own vocal music, complete with backing instrumental and vocal tracks, special effects, harmonies, bass-lines, and drum-beats. Primarily appealing to aspiring musicians, the Compact Sound Studio would also be ideal for motivational speakers, priests and ministers, actors, and more.
