1. A 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 enclosing 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;
an accumulator configured for accumulating air and for reducing noise originating from a pumping action of the pump unit, the accumulator being in fluid communication with an outlet of the pump unit and with an inlet of the inflatable air chamber; and
a pump unit suspension system configured for reducing noise originating from operation of the pump unit, the pump unit suspension system comprising:
a tubular casing configured 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 configured 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 configured for sealing the tubular casing, arranged at ends of the tubular casing, and
an outer suspension configured for suspending the tubular casing with respect to the housing, arranged between the tubular casing and the housing, wherein the noise produced by the haptic respiration simulator is below 40 dBA (decibels A) measured at a position outside of the haptic respiration simulator, at a distance of 25 cm (centimeter).
