  "abstract": "A wireless speaker system may include a primary speaker including a first transceiver and a second transceiver and programmed to receive audio data from a user device at the first transceiver, and at least one secondary speaker including a receiver and programmed to receive a wireless signal including the audio data from the primary speaker at the receiver, each speaker configured to transmit audio signals consistently there between based on the received audio data.",
  "claims": [
    "1. A wireless speaker system comprising: a primary speaker including a first transceiver and a second transceiver and programmed to receive audio data from a user device at the first transceiver; and at least one secondary speaker including a receiver and programmed to receive a wireless signal including the audio data from the primary speaker at the receiver, each speaker configured to transmit audio signals consistently there between based on the received audio data; wherein the primary speaker is configured to receive the audio data from the user device via a first interface and wherein the secondary speaker is configured to receive the audio data from the primary speaker via a second interface, the first interface facilitating the transmission of the audio data at a first frequency band and the second interface facilitating the transmission of the audio data over a second frequency band; wherein an exchange of enrollment data is transmitted between the primary and secondary speakers over a frequency band separate and distinct from the first and second frequency bands.",
    "2. The system of claim 1, wherein the frequency band separate and distinct from the first and second frequency bands is an industrial, scientific and medical (ISM) band.",
    "3. The system of claim 1, wherein the wireless signal includes at least one of volume data, feedback data, and a predefined frequency of the second interface.",
    "4. The system of claim 1, wherein the primary speaker includes a mode switch for instructing the primary speaker to operate in a primary mode where the primary speaker receives the audio data from the user device and a secondary mode where the primary speaker receives the audio data from another primary speaker."

  "description_excerpt": "Described herein is a wireless speaker system.\n\nLoudspeakers are used to emit sound based on an audio input signal. The audio input signals may be supplied from any number of sources and may be in any number of forms (e.g., electronic files such as.wav,.mp3, etc.). Often times, multiple loudspeakers may be desired to allow sounds to reach across a large physical area. For example, multiple speakers may be used so that sound can be heard throughout a large room or auditorium, or across a large outdoor area such as an outdoor patio, pool area, etc. Existing systems, however, require the speakers to be tethered together by a wire.\n\nA wireless speaker system may include a primary speaker including a first transceiver and a second transceiver and programmed to receive audio data from a user device at the first transceiver, and at least one secondary speaker including a receiver and programmed to receive a wireless signal including the audio data from the primary speaker at the receiver, each speaker configured to transmit audio signals consistently there between based on the received audio data.\n\nA speaker for a wireless speaker system may include a receiver configured to receive a first wireless signal from a user device, the wireless signal including audio data, a transmitter configured to transmit another second wireless signal including the received audio data; and a transducer configured to transmit an audio signal based on the received audio data.",
