    Abstract: The speakerphone accessory 100 has a high-level speaker assembly 222 that includes a transducer (500, figure 5) coupled to first and second resonators. The first resonator (502, figure 5) is most efficient at a high frequency and the second resonator (504, figure 5) has maximum response at a low frequency. The frequency ranges produced by the first and second resonators (502 and 504, figure 5) overlap to reproduce frequencies between the high and low frequencies. The high-level speaker assembly 222 provides an acoustic bandpass having improved response when compared to the response of the transducer (500, figure 5) alone. The speakerphone accessory 100 has a housing 130 and porting structure which allows the accessory 100 and attached portable telephone 102 to be used in a variety of positions without obstructing sound generated by the high level speaker assembly 222.

    Abstract: A speakerphone accessory (100) is provided for use with a portable telephone (102). The speakerphone accessory (100) has a high-level speaker assembly (222) that includes a transducer (500) coupled to first and second resonators (502, 504). The first and second resonators (502, 504) are designed so that the first resonator (502) is most efficient at a high frequency while the second resonator (504) has maximum response at a low frequency. The frequency ranges produced by the first and second resonators (502, 504) overlap to reproduce frequencies between the high and low frequencies. The high-level speaker assembly (222), therefore, provides an acoustic bandpass having improved response when compared to the response of the transducer (500) alone. In addition, the speakerphone accessory (100) has a housing (130) and porting structure which allows the accessory (100) and attached portable telephone (102) to be used in a variety of positions without obstructing sound generated by the high-level speaker assembly (222).

    Abstract: Un método para la ampliacion de senales de audio que comprende obtener (222) una primera senal de audio de un primer elemento de microfono físico y obtener una segunda senal de audio de un segundo elemento de microfono físico. Las senales de audio se procesan en red (226) para generar un elemento virtual lineal de primer orden y un elemento virtual no lineal de orden par. El procesamiento en red (226) incluye combinar el elemento virtual lineal de primer orden y el elemento virtual no lineal de orden par para generar una senal de audio direccional con un haz de audio principal.

    Abstract: Disclosed is a portable audio device and a quick-disconnect passive acoustic cover. The portable audio device includes a housing and a speaker supported by the housing that have a first system frequency response. The speaker of the portable audio device has a first side and a second side associated with a first audio port and a second audio port, associated with a first acoustic load and a second acoustic load respectively. The housing is configured to removably receive the cover which is configured to redefine at least one of the first acoustic load and the second acoustic load to replace the first system frequency response with a second system frequency response. The cover provides one or more additional surrounding structures, which replace the inherent frequency response with an improved frequency response. Different embodiments of the disclosed cover provide a plurality of sound quality enhancement options to a user.

    Abstract: A wireless device (100) provides coordinated audio playback. The device (100) includes a network interface (112) that receives a signal from a sending or originating device (401) and sends a reply to the signal. A network delay value is then calculated based on the reply to the signal. The wireless device (100) then receives a location of the originating device (401) and at least a portion of an audio file. The wireless device (100) generates audio from the audio file, with the generation being coordinated with audio generation by the originating device (401) based upon the network delay value and the distance between the wireless device (100) and the originating device (401).
