The loudspeaker emits acoustic signals in a direction parallel to the wall, when the housing is coupled to the wall, with the acoustic signals reflecting off the wall. The device may produce a sound masking noise or play a sound recorded on an internal memory. The device may include an electric plug or be adapted to replace an electric outlet faceplate. The device may have electric pass-through outlets and may be powered by the source of electric power. The device may be controlled remotely, for example via an Internet of Things (IoT) platform. ## Claims ### Claim 1 A wireless sound-emitting device, comprising: a housing, the housing comprising a front face and a rear face, the front face having at least one electric socket, the rear face of the housing comprising at least one corresponding electric plug, wherein the at least one electric socket is configured to pass-through an electric power signal to the corresponding electric plug such that the housing presents a standard electric outlet; at least one loudspeaker adapted to emit acoustic signals; a control module in electrical communication with the at least one loudspeaker to drive the at least one loudspeaker with an electric audio signal, the control module being adapted to receive power from the at least one electric plug, the control module adapted to convert at least one digital sound signal into the electric audio signal to drive the at least one loudspeaker, the electric audio signal comprising a sound-masking signal; and a wireless communications module in electrical communication with the control module. ### Claim 2 (depends on 1) The wireless sound-emitting device of claim 1, further including: a memory module in electrical communication with the control module, the memory module storing digital sound files comprising the at least one digital sound signal; and the control module being further adapted to convert the at least one digital sound signal comprised in the digital sound files into the electric audio signal to drive the at least one loudspeaker. ### Claim 3 (depends on 1) The wireless sound-emitting device of claim 1, further including: the wireless communications module being adapted to wirelessly receive digital sound data comprising the at least one digital sound signal; and the control module being further adapted to convert the at least one digital sound signal comprised in the wirelessly received digital sound data into the electric audio signal to drive the at least one loudspeaker. ### Claim 4 (depends on 1) The wireless sound-emitting device of claim 1, further including: one or more status indicator lights, each of the status indicator lights being responsive to a status of one or more of: the at least one loudspeaker, the control module, a source of electric power, and the wireless communications module. ### Claim 5 (depends on 4) The wireless sound-emitting device of claim 4, wherein the one or more status indicator lights is adapted to emit light in a direction parallel to a surface of a wall when the at least one electric plug is coupled to an outlet in the wall. ### Claim 6 (depends on 1) The wireless sound-emitting device of claim 1, further including: an acoustic enclosure acoustically coupled to a rear end of the at least one loudspeaker. ### Claim 7 (depends on 6) The wireless sound-emitting device of claim 6, wherein the acoustic enclosure is a sealed or ported enclosure. ### Claim 8 (depends on 1) The wireless sound-emitting device of claim 1, wherein the at least one loudspeaker has a largest aperture dimension of less than about 3 centimeters. ### Claim 9 (depends on 1) The wireless sound-emitting device of claim 1, wherein the housing further including a protective grille covering the at least one loudspeaker. ### Claim 10 A system for managing the sound environment of one or more rooms, the system including: at least one wireless sound-emitting device, the at least one wireless sound-emitting device comprising: a housing, the housing comprising a front face and a rear face, the front face having at least one electric socket, the rear face of the housing comprising at least one corresponding electric plug, wherein the at least one electric socket is configured to pass-through an electric power signal to the corresponding electric plug such that the housing presents a standard electric outlet;
