Haptic respiration simulator for relaxing a user by simulating a respiration, the respiration being sensible by a body part of the user, wherein the haptic respiration simulator comprises: - a housing for housing components of the haptic respiration simulator; - an inflatable air chamber , outside of the housing and configured to simulate a respiration by repeated inflation and deflation of the inflatable air chamber ; - a pump unit , in fluid communication with the inflatable air chamber and configured to pump a volume of air into the inflatable air chamber , the pump unit being positioned inside the housing ; characterised by - a pump unit suspension system for reducing noise originating from operation of the pump unit , the pump unit suspension system comprising: ∘ a tubular casing for receiving the pump unit at an inside thereof, the tubular casing having a substantially closed circumferential wall that prevents at least a part of the sound waves resulting from operation of the pump unit to transfer outside the tubular casing , the tubular casing being positioned inside the housing ; ∘ an inner suspension for suspending the pump unit with respect to the tubular casing , the inner suspension being positioned inside the tubular casing , between the pump unit and the tubular casing ; ∘ a pair of end caps for sealing the tubular casing , arranged at ends of the tubular casing , and ∘ an outer suspension for suspending the tubular casing with respect to the housing , arranged between the tubular casing and the housing . - a housing for housing components of the haptic respiration simulator; - an inflatable air chamber , outside of the housing and configured to simulate a respiration by repeated inflation and deflation of the inflatable air chamber ; - a pump unit , in fluid communication with the inflatable air chamber and configured to pump a volume of air into the inflatable air chamber , the pump unit being positioned inside the housing ; characterised by - a pump unit suspension system for reducing noise originating from operation of the pump unit , the pump unit suspension system comprising: ∘ a tubular casing for receiving the pump unit at an inside thereof, the tubular casing having a substantially closed circumferential wall that prevents at least a part of the sound waves resulting from operation of the pump unit to transfer outside the tubular casing , the tubular casing being positioned inside the housing ; ∘ an inner suspension for suspending the pump unit with respect to the tubular casing , the inner suspension being positioned inside the tubular casing , between the pump unit and the tubular casing ; ∘ a pair of end caps for sealing the tubular casing , arranged at ends of the tubular casing , and ∘ an outer suspension for suspending the tubular casing with respect to the housing , arranged between the tubular casing and the housing . ∘ a tubular casing for receiving the pump unit at an inside thereof, the tubular casing having a substantially closed circumferential wall that prevents at least a part of the sound waves resulting from operation of the pump unit to transfer outside the tubular casing , the tubular casing being positioned inside the housing ; ∘ an inner suspension for suspending the pump unit with respect to the tubular casing , the inner suspension being positioned inside the tubular casing , between the pump unit and the tubular casing ; ∘ a pair of end caps for sealing the tubular casing , arranged at ends of the tubular casing , and ∘ an outer suspension for suspending the tubular casing with respect to the housing , arranged between the tubular casing and the housing . <EOS>
