[0030] image 3 is a cross-sectional view of the vibration shock absorbing mechanism 1 according to the first embodiment of the present invention. The vibration shock absorbing mechanism 1 includes a housing 2 , a shock absorbing element 4 and a resonance damping element 5 . The shock absorbing element 4 is arranged between the casing 2 and the object 3 to be protected arranged inside the casing 2 . The resonance-damping element 5 consists of a material having different vibration-damping properties than the shock-absorbing element 4 and is arranged between the object 3 and the shock-absorbing element 4 .

[0031] Each shock absorbing member 4 is substantially C-shaped in cross-section, and it has a pair of first upper section 4a and second lower section 4b, and a third middle section 4c connecting the first and second sections 4a and 4b. The shock absorbing member 4 is attached to the left and right sides of the object 3 by partially sandwiching the object 3 from the upper a...

[0059] In the first embodiment, as image 3 As shown in , each resonance damping element 5 intervenes over the entire contact surface between the first or second segment 4a or 4b of the corresponding shock absorbing element 4 and the object 3 to be protected. In contrast, refer to Figure 13 , each resonance damping element 5 according to the second embodiment of the invention intervenes a part of the contact surface between the first or second section 4a or 4b of the corresponding shock absorbing element 4 and the object 3 .

[0060] This means that, in the second embodiment, each shock-absorbing element 4 is partly in direct contact with the object 3 . Consequently, shocks and vibrations in the resonant frequency range of the object 3 are greater compared to structures in which the resonance damping element 5 intervenes over the entire contact surface between the object 3 and the first and second sections 4a, 4b of the shock absorbing element 4 . However, if the protected...

Abstract

A vibration-shock absorbing mechanism that protects an object disposed in a housing includes a shock-absorbing member that is disposed in the housing and absorbs a shock, and a resonance-damping member that is disposed between the object and the shock-absorbing member and dampens a vibration and shock in a predetermined frequency range including a resonant frequency of the object.

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application No. JP2005-122277 filed in the Japan Patent Office on Apr. 20, 2005, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a vibration shock absorbing mechanism that reduces vibration of an object placed in a casing when vibration or shock is applied to the casing, and a content reproduction device equipped with such a mechanism. Background technique [0004] In portable electronic devices, considering better portability, a compact and low-profile structure is highly desired. In addition to compactness and small form factor construction, portable electronic devices are more resistant to vibration and shock than stationary devices because they are used in mobile environments. In particular, resistance to vibration and shock is more necessary in a portable content repr...
