Embodiment Construction

[0049] The present disclosure describes various embodiments of devices configured to reduce the transmission of noise and vibration frequencies from internal components to external surfaces. More generally, applicants have recognized and understood that it would be beneficial to provide a suspension system within the device that more accurately and economically minimizes the transmission of acoustic and vibrational energy. A suspension system includes a rigid support, an operating element (such as a pump assembly) positioned within the rigid support and containing a drive frequency when the device operates, and a suspension including a resilient element engaged with the rigid support and configured to An elastic force of one or more degrees of freedom is created that resists the vibrations produced by the operating element.

[0050] The suspension system is configured such that the natural frequencies in one or more degrees of freedom of the suspension system are tuned to with...

Abstract

A suspension system (22) configured to minimize transmission of acoustic and vibratory energy in a device, the suspension system comprising: (i) a rigid support (24); (ii) an operating element (16) positioned within the rigid support and including a drive frequency when the device is operated; and (iii) an elastic element (26) engaging the rigid support and configured to generate an elastic force of one or more degrees of freedom against vibrations generated by the operating element; wherein the natural frequency in one or more degrees of freedom (in the degree of freedom of interest) of the suspension system is tuned by the suspension to a narrow resonant frequency range, and wherein the resonant frequency is less than the drive frequency.

Description

technical field [0001] The present disclosure generally relates to a suspension system configured to minimize the transmission of acoustic and vibrational energy generated by a pump or motor to an outer housing to reduce audible noise perceived by a user. Background technique [0002] Due to moving or vibrating parts, the device can be noisy and exhibit unwanted vibrations. Noise or vibration associated with a consumer device can limit or prevent the use of the device due to the user's volume or the user's concerns about others who may be disturbed. This can lead to dissatisfaction with the consumer device, inconsistent use of the device, or inability to use the device, thereby reducing or preventing the full potential benefits that can be obtained from using the device. [0003] An oral irrigator is just one example of a consumer device that generates unwanted noise and vibration. Oral irrigators use a pump to pump fluid from a low-pressure reservoir into a high-pressure ...
