Portable speaker with automatic detecting input channel
Various implementations include portable speakers configured to adjust audio output based on detected input connections. In certain cases, a portable speaker includes: an enclosure having: at least one electro-acoustic transducer for providing an audio output, a processor coupled with the at least one transducer; and an audio input module coupled with the processor for receiving audio input signals; a set of input channels each for receiving a hard-wired audio input connection at the enclosure; a set of wireless input channels for receiving audio input from a source device; and a set of docks for housing two or more wireless transmitters configured to provide the audio input via the set of wireless input channels.
1 . A portable speaker, comprising:
an enclosure housing:
at least one electro-acoustic transducer for providing an audio output; and
a processor coupled with the at least one transducer;
an input channel for receiving a hard-wired audio input connection;
at least two wireless input channels for receiving an audio input from a source device via a wireless connection, wherein the processor is configured to:
adjust an audio signal received from the hard-wired audio input connection if a source device is already connected via the wireless connection; and
at least one wireless transmitter detachably housed in the enclosure, each wireless transmitter for enabling the wireless connection between the source device and a corresponding one of the wireless input channels.
2 . The portable speaker of claim 1 , wherein adjusting the audio signal received from the hard-wired audio input connection if a source device is already connected via the wireless connection includes outputting one of:
the audio signal received from the hard-wired audio input connection as primary audio, or
an audio signal received from the wireless connection as primary audio.
3 . The portable speaker of claim 1 , wherein the enclosure further houses an audio input module coupled with the processor for receiving audio input signals.
4 . The portable speaker of claim 1 , wherein the processor switches the input channel to an effects loop in response to detecting the hard-wired audio input connection while the source device is already connected via the wireless connection.
5 . The portable speaker of claim 1 , wherein adjusting the audio signal comprises adjusting a pre-amplification order of the audio signal prior to providing the audio output.
6 . The portable speaker of claim 1 ,
wherein the at least one wireless transmitter includes at least two wireless transmitters detachably housed in the enclosure, each wireless transmitter for enabling the wireless connection between the source device and a corresponding one of the wireless input channels.
7 . The portable speaker of claim 6 , wherein each of the wireless transmitters is configured to connect the source device with the portable speaker in response to detecting a connection with the source device.
8 . The portable speaker of claim 1 , wherein the processor is configured to select the audio input based on a command from an application run on a connected smart device.
9 . The portable speaker of claim 1 , further comprising a hard-wired power connector for charging a battery in the enclosure and powering the portable speaker.
10 . A public address (PA) speaker comprising the portable speaker of claim 1 .
11 . The portable speaker of claim 1 , wherein the input channel for receiving the hard wired audio input connection is at the enclosure of the portable speaker.
12 . A portable speaker, comprising:
an enclosure having:
at least one electro-acoustic transducer for providing an audio output,
a processor coupled with the at least one transducer; and
an audio input module coupled with the processor for receiving audio input signals;
a set of input channels each for receiving a hard-wired audio input connection at the enclosure;
a set of wireless input channels for receiving audio input from a source device; and
a set of docks for housing two or more wireless transmitters configured to provide the audio input via the set of wireless input channels.
13 . The portable speaker of claim 12 , wherein each of the set of wireless input channels corresponds to an input channel for receiving a hard-wired audio input connection.
14 . The portable speaker of claim 12 , wherein the processor is configured to:
adjust an audio signal received from the hard-wired audio input connection if a source device is already connected via the wireless connection.
15 . The portable speaker of claim 14 , wherein adjusting the audio signal received from the hard-wired audio input connection if a source device is already connected via the wireless connection includes outputting one of:
the audio signal received from the hard-wired audio input connection as primary audio, or
an audio signal received from the wireless connection as primary audio.
16 . The portable speaker of claim 12 , wherein the enclosure houses a battery configured to power the at least one transducer, the processor, and the audio input module.
17 . The portable speaker of claim 12 , further comprising at least two wireless transmitters detachably housed in the enclosure, each wireless transmitter for enabling the wireless connection between the source device and a corresponding one of the wireless input channels.
18 . The portable speaker of claim 17 , wherein each of the wireless transmitters is configured to connect the source device with the portable speaker in response to detecting a connection with the source device.
19 . The portable speaker of claim 12 , wherein the processor is further configured to:
receive the audio input from the source device via the wireless connection as a digital audio input; and
convert the digital audio input to an analog audio signal.
20 . The portable speaker of claim 12 , wherein the set of wireless input channels comprises at least two wireless input channels.
