Abstract: A piezoelectric speaker (10) includes: a piezoelectric film (35); a fixing face (17) for fixing the piezoelectric film (35) to a support; and an interposed layer (40) disposed between the piezoelectric film (35) and the fixing face (17). The interposed layer (40) has a holding degree of 5×108 N/m3 or less.

Abstract: An acoustic device includes: at least one processor, and at least one memory device that stores a plurality of instructions, which when executed by the at least one processor, causes the at least one processor to operate to: acquire data on a mixed sound of a reproduction sound of a first sound data output from a first speaker and a reproduction sound of a second sound data output from a second speaker, the mixed sound being picked up by a sound pickup device directed toward the first speaker, calculate a first similarity degree indicating similarity between the data on the mixed sound and the first sound data and a second similarity degree indicating similarity between the data on the mixed sound and the second sound data, and determine connection states of the first speaker and the second speaker based on the first similarity degree and the second similarity degree.

Abstract: An information processing apparatus includes a processor that performs a separate process to separate a content signal into a primary component which is an objective sound and a secondary component which is other than the objective sound, a speaker that outputs the primary component, and a transmitter that transmits the secondary component to another apparatus.

Abstract: A memory portion stores automated reproducing setting data that associates content input sources with necessariness/unnecessariness of automated reproduction of content. A control portion, when an operation-display portion or a remote control reception portion accepts selection of a content input source, judges whether or not automated reproduction is necessary on content that is inputted from the currently selected input source, based on the automated reproducing setting data. Also, the control portion starts outputting, at an audio signal output portion and a video signal output portion, a reproducing signal on the content that is inputted from the currently selected input source, when judging that automated reproduction of the content is necessary.

Abstract: A content reproduction apparatus includes: an information receiving unit that receives first information from a first user terminal capable of providing a first content, the first information including the first content, the information receiving unit receiving second information from a second user terminal capable of providing a second content, the second information including the second content; a list transmission unit that transmits a shared list to the first user terminal, the shared list being created based on the first and second information and including information indicating the first and second contents; a reproduction request receiving unit that receives, from the first user terminal, a request of one of the first and second contents; and a reproduction unit that acquires the requested content from a user terminal that is capable of providing the requested content that is one of the first and second user terminals, and reproduces the acquired content.
