Abstract:
A sound output apparatus is provided, which includes an outer case having an upper portion with an opening formed upward, and a lower portion with sound holes formed therethrough, a first sound output unit provided at an upper side within the outer case and capable of outputting sounds of a first frequency band, a second sound output unit provided at a lower side within the outer case and capable of outputting sounds of a second frequency band, and a conveying device provided below the first sound output unit and capable of moving the first sound output unit up and down, wherein the conveying device allows the first sound output unit to protrude upwardly such that sounds are output between the outer case and the first sound output unit.
Abstract:
The present invention discloses a speaker enclosure, in particularly a blown molded hollow pressure vessel. The present invention discloses a speaker enclosure, which is formed at once and sealed better. The thickness of the enclosure can be very thin and hence reduce the weight of the speaker. The present invention discloses a speaker enclosure, which can use many of the existing products to replace the traditional speaker enclosure. The present invention discloses a speaker enclosure, which its audible unit directly connects to the blow opening tightly. The present invention discloses a speaker enclosure, which its audible unit is provided with a seal. When the audible unit and speaker enclosure are assembled, the seal and enclosure opening thereby are completely tight assembled together.
Abstract:
A loudspeaker system comprising: a bass enclosure (112) housing a woofer; a driver array (150) including a plurality of drivers, and signal electronics driving the woofer and driver array, wherein the driver array is attached in front of the bass enclosure in a first configuration and is attached at an elevation above the bass enclosure in a second configuration, the driver array supported by one or more leg extensions (160) in the second configuration, the one or more leg extensions providing mechanical support for the driver array and providing an electrical connection (625) between the driver array and the signal electronics.
Abstract:
An electrodynamic loudspeaker assembly having an electrodynamic loudspeaker and first and second compensation filters. The electrodynamic loudspeaker includes a voice coil arranged in an air gap of a magnetically permeable structure and a compensation coil wound around a portion of the magnetically permeable structure. The first compensation filter filters an audio input signal to the loudspeaker assembly with a first frequency response to generate a voice coil compensation signal for application to the voice coil. The second compensation filter filters the audio input signal to the loudspeaker assembly with a second frequency response to generate a second compensation signal for application to the compensation coil. The first and second frequency responses, across a predetermined audio frequency range, suppress a time-varying or AC magnetic flux in the air gap caused by voice coil current such that magnetic flux modulation in the air gap of the loudspeaker is suppressed.
Abstract:
In an example embodiment, an apparatus includes an enclosure having a loudspeaker mounted therein. The apparatus also includes an IC package mounted inside the enclosure. The IC package includes an amplifier configured to amplify an input audio signal, received at an input of the amplifier, to produce a drive signal. The amplifier is configured to drive the loudspeaker with the drive signal via an output of the amplifier. The IC package also includes a pressure sensor configured to output a status signal, indicative of a sound pressure level inside the enclosure, from an output terminal of the pressure sensor. The apparatus also includes an audio processing circuit connected to the amplifier and configured to adjust strength of the drive signal produced by the amplifier, as a function of the sound pressure level indicated by the status signal.
Abstract:
An integrated loudspeaker assembly along with associated methods and systems for enhancing audio output from a consumer electronic device including such an integrated loudspeaker assembly are disclosed. More particularly an integrated loudspeaker assembly configured to utilize the enclosure of an associated consumer electronic device for back volume is disclosed. Methods and systems for optimizing the audio performance of a consumer electronic device with an integrated loudspeaker assembly are also disclosed.
Abstract:
There is provided a sound reproduction apparatus including a sub-woofer unit and a plurality of wireless speakers. A method of speaker charging and speaker calibration using the sound reproduction apparatus is also provided. The sub-woofer unit may be configured to perform tasks of both charging a power source in each of the plurality of wireless speakers; and calibrating speaker identity for each of the plurality of wireless speakers. It is advantageous that both of the tasks are performed when the plurality of wireless speakers is coupled to the sub-woofer unit. The speaker identity may include, for example, left front, right front, left rear, right rear, and centre.
