An example stimulation device configured to stimulate a portion of a body of a user comprises a housing that includes a casing and a covering. The casing includes a nozzle, a motor disposed within the casing configured to generate stimulation patterns, a drive shaft connected to the motor, a sensor configured to detect changes in the rotation of the draft shaft, a controller, and a battery. The covering covers a portion of the casing. ## Claims ### Claim 1 A stimulation device configured to stimulate a portion of a body of a user, comprising: a housing having a first end, a second end opposite the first end, a nozzle, and a silicone covering, the silicone covering disposed such that it covers a portion of the first end and a portion of the second end, the housing defining a chamber having a first opening configured to receive said portion of said body, the chamber having a chamber surface that is defined by the silicone covering; a motor disposed within the housing and configured to generate a stimulation pattern, the motor configured to transmit the stimulation pattern into the chamber; a controller disposed within the housing and configured to control the motor; and a battery disposed within the housing configured to provide power to the motor and the controller. ### Claim 2 (depends on 1) The stimulation device of claim 1, wherein the silicone covering comprises a single piece. ### Claim 3 (depends on 2) The stimulation device of claim 2, wherein the chamber surface can extend between one and twenty millimeters towards or away from the first opening when the motor is activated. ### Claim 4 (depends on 1) The stimulation device of claim 1, wherein the controller contains pre-set stimulation patterns that may be communicated to the motor. ### Claim 5 (depends on 4) The stimulation device of claim 4, wherein the user interacts with the controller to choose stimulation patterns through a set of control buttons. ### Claim 6 (depends on 5) The stimulation device of claim 5, wherein the housing is waterproof. ### Claim 7 (depends on 6) The stimulation device of claim 6, wherein the chamber comprises a proximal end and a middle portion; and wherein a diameter of the middle portion is greater than a diameter of the proximal end. ### Claim 8 (depends on 7) The stimulation device of claim 7, wherein the housing is comprised of a casing; and wherein the casing comprises at least a first piece, a second piece, a third piece, and a fourth piece. ### Claim 9 (depends on 8) The stimulation device of claim 8, wherein the first piece, the second piece, the third piece, and the fourth piece are comprised of plastic. ### Claim 10 (depends on 9) The stimulation device of claim 9, wherein the covering is disposed adjacent the first piece, the second piece, and the third piece. ### Claim 11 (depends on 10) The stimulation device of claim 10, wherein the housing is curved along its length and forms an ergonomic shape. ### Claim 12 A stimulation device configured to stimulate a portion of a body of a user, comprising: a housing having a first end, a second end opposite the first end, a nozzle defined by the first end, and a silicone covering, the silicone covering disposed such that it covers a portion of the first end and a portion of the second end, the housing defining a chamber having a first opening configured to receive said portion of said body, the nozzle having a base defining a groove disposed adjacent the chamber, the chamber having a chamber surface that is defined by the silicone covering, the chamber surface being capable of moving toward and away from the first opening when in use; a motor disposed within the housing and configured to generate a stimulation pattern, the motor configured to transmit the stimulation pattern into the chamber; a controller disposed within the housing and configured to control the motor; and a battery disposed within the housing configured to provide power to the motor and the controller. ### Claim 13 (depends on 12) The stimulation device of claim 12, wherein no portion of the housing that defines the chamber is removeable or replaceable. ### Claim 14 (depends on 13) The stimulation device of claim 13, wherein no portion of the silicone covering is removeable or replaceable. ### Claim 15 (depends on 12) The stimulation device of claim 12, wherein the first opening has a first diameter of between five millimeters and thirty millimeters. ### Claim 16 (depends on 15) The stimulation device of claim 15, wherein the chamber defines a second diameter at the widest portion of the chamber; and wherein a second diameter is between five millimeters and thirty millimeters. ### Claim 17 (depends on 16) The stimulation device of claim 16, wherein the chamber defines a depth extending from the first opening to the base of the nozzle; and wherein the depth is between five millimeters and fifty millimeters. ### Claim 18 (depends on 12) The stimulation device of claim 12, wherein the motor comprises a drive shaft. ### Claim 19 (depends on 12) The stimulation device of claim 12, wherein the chamber surface can extend between one and twenty millimeters towards or away from the first opening when the motor is activated. ### Claim 20 A stimulation device configured to stimulate a portion of a body of a user, comprising: a housing having a first end, a second end opposite the first end, a nozzle defined by the first end, and a silicone covering, the silicone covering disposed such that it covers a portion of the first end and a portion of the second end, the housing defining a chamber having a first opening configured to receive said portion of said body, the nozzle having a base defining a groove disposed adjacent the chamber, the chamber having a chamber surface that is entirely defined by the silicone covering, the chamber surface being capable of moving toward and away from the first opening when in use; a motor disposed within the housing and configured to generate a stimulation pattern, the motor configured to transmit the stimulation pattern into the chamber; a controller disposed within the housing and configured to control the motor; and a battery disposed within the housing configured to provide power to the motor and the controller.
