Abstract: Provided herein are system, apparatus, device, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for transmitting messages to a display device based on detected audio output from the display device. In a given embodiment, a digital media player can transmit a message to the display device to control the audio output of the speaker using a transmission protocol, and transmit a set of instructions to the remote control device to confirm the display device processed the message by determining whether an attribute associated with the audio output from the speaker is within a predetermined threshold. In response to receiving a message that an attribute associated with the audio output is within a predetermined threshold, the digital media player can determine that the display device is enabled to receive communication via the transmission protocol.

Abstract: Systems and methods for volume control over intercom trunk lines. One example method includes receiving, from a first keypanel coupled to a first intercom, a call request identifying a remote keypanel coupled to a second intercom. The method includes transmitting a trunk request based on the call request and receiving a trunk setup message. The method includes activating a first crosspoint to provide a two-way audio connection between the first and second intercom devices. The method includes applying a trunk gain value to the first crosspoint based on the remote keypanel and transmitting, with an audio gain based on the trunk gain value, an audio stream received from the first keypanel. The method includes receiving, from the second intercom, a gain adjustment value associated with the first keypanel and the remote keypanel and applying an adjusted trunk gain value to the first crosspoint based on the gain adjustment value.

Abstract: An audio transmission system of the present invention includes: an unmanned aircraft; a steering terminal that is used to steer the unmanned aircraft; and an information terminal configured to access a server providing a service for translating text data created in an official language of a country into a designated language other than the official language, and converting the translated text data into audio data, the information terminal being able to download the audio data from the server. The information terminal transmits the audio data in the designated language downloaded from the server to the unmanned aircraft, and the unmanned aircraft outputs the audio data in the designated language as an audio message from a speaker attached to an airframe.

Abstract: A sound emitting device (10) for providing at least one new sonic or subsonic frequency as a by-product of emitting a waveform of at least two ultrasonic frequencies whose difference in value corresponds to the desired new sonic or subsonic frequency. The device includes a parametric emitting perimeter or plurality of emitter segments (13) positioned around a central open section (15). This open section (15) is structured with a diagonal width greater than a cross-sectional diagonal of the parametric emitting perimeter. An ultrasonic frequency source (60) and sonic/subsonic frequency generator (62) arc coupled together to a modulating circuit (61) for mixing an ultrasonic frequency signal with an electrical signal corresponding to the at least one new sonic or subsonic frequency. The modulator output is coupled to the emitting perimeter (64) which comprises ultrasonic frequency emitting material for propagating the mixed waveform into air for demodulating the waveform to generate the at least one new sonic or subsonic frequency.

Abstract: A portable audio apparatus allows a user to sing along with the recorded song, the user's voice and recorded song being outputted through a speaker. The apparatus permits the recorded lyrics or recorded tune of the song to be substantially eliminated prior to being reproduced by the speaker. The apparatus can operate in a fast forward or reverse mode and will stop between adjacent songs. A power savings circuit interrupts the supply of power to a motor to stop the latter from continuing to operate on a fast forward or reverse mode.

Abstract: A multipurpose sound communication system for use anywhere. This system may thus be used in a number of ways not described in the specification, but will be found useful in many, if not all, emergency vehicles including, but not limited to, ambulances and police patrol cars. The system employs one voltage controlled oscillator (VCO) with six selectively adjustable inputs. One of the inputs if OFF. Three inputs provide different corresponding siren sounds. One input places the radio on the speaker. Another input provides for public address and manual control of the siren. Speaker assembly negative feedbacks are provided for signal balance. Two negative feedbacks are selectively provided. A manual control circuit provides ramp voltages for siren control through the VCO. A transistor switch is driven to cut-off to prevent VCO operation when the siren frequency falls below a predetermined frequency.
