The device has various parametric speakers arranged in a pattern to project sounds in a narrow field while preventing dispersion of sounds to nearby areas. The device can be connected to other electronic equipment by wires or wirelessly, and can be removed and used in different settings. This device has particular application in delivering sounds to infants and toddlers to soothe them while the same sounds are not heard by adults nearby. ## Claims ### Claim 1 A sound projection device, comprising: a hollow body with a thickness, a front and a back, the hollow body configured to contain multiple components; a plurality of parametric speakers arranged with the hollow body and completely contained within the hollow body; a wireless communication means configured to communicate with at least one remote computing device and to operatively connect to the plurality of parametric speakers, the wireless communication means is configured to receive signals from the remote computing device and operate the plurality of parametric speakers; a power source; multiple wires configured to physically and operatively connect the plurality of parametric speakers to each other, to the wireless communication means, and to the power source; a sound directing panel attached to the front cover: a front cover attached to the front of the body; and a back cover attached to the back of the body; wherein the parametric speakers are wired parallelly, wherein the plurality of parametric speakers are arranged in a cluster close to each other, the parametric speakers are without sound directive covers and are not surrounded, wherein the plurality of parametric speakers are operatively connected to each other and not to any other portions and wherein the sound projected from the sound projection device can be heard by a person positioned at 12 inches from the sound projection device. ### Claim 2 (depends on 1) The sound projection device of claim 1, wherein the hollow body is in substantially tubular shape. ### Claim 3 (depends on 1) The sound projection device of claim 1, wherein the hollow body is in substantially rectangular shape. ### Claim 4 (depends on 1) The sound projection device of claim 1, further comprising an on/off switch. ### Claim 5 (depends on 1) The sound projection device of claim 1, wherein the sound directing panel is in the shape of a baseball visor attached to the front cover at an angle. ### Claim 6 (depends on 5) The sound projection device of claim 5, wherein the angle is 45°. ### Claim 7 (depends on 1) The sound projection device of claim 1, wherein the back is configured to be attachable to a mounting pad. ### Claim 8 (depends on 7) The sound projection device of claim 7, further comprising a mounting pad configured to be attachable to the back of the body. ### Claim 9 (depends on 8) The sound projection device of claim 8, further comprising a detachable, flexible handle attached to the mounting pad. ### Claim 10 (depends on 9) The sound projection device of claim 9, wherein the detachable, flexible handle is adjustable in length. ### Claim 11 (depends on 9) The sound projection device of claim 9, further comprising a detachable clip attached to the detachable, flexible handle. ### Claim 12 (depends on 8) The sound projection device of claim 8, further comprising a strap attachable to the mounting pad. ### Claim 13 (depends on 12) The sound projection device of claim 12, wherein the strap has a Velcro attachment mechanism on the strap's body. ### Claim 14 (depends on 12) The sound projection device of claim 12, wherein the strap has eyelets to change the length in use. ### Claim 15 (depends on 8) The sound projection device of claim 8, further comprising a volume adjustment button. ### Claim 16 (depends on 8) The sound projection device of claim 8, further comprising a remote computing device configured to operatively connect to the sound projection device via a wireless communication means. ### Claim 17 (depends on 16) The sound projection device of claim 16, wherein the remote computing device is a smart phone, a tablet, a laptop, or a desktop computer. ### Claim 18 (depends on 16) A method to provide sounds to a child, the method comprising: providing a sound projection device as in claim 16; orienting the sound projection device towards the child; activating the sound projection device using the remote computing device; and playing sounds from the remote computing device.
