Thereby, replace only using non-weaving cloth, in this embodiment as the non-weaving cloth of the resonance attenuating elements 42 of content playback unit 11 have effective attenuation basically 1KHz in the equipment resonance frequency scope of 3KHz vibration and the ability of impact.
Second embodiment
In first embodiment, as shown in Figure 3, each resonance attenuating elements 5 get involved first or second section 4a of corresponding impact-absorbing element 4 or 4b and the object 3 protected between entire contact surface.In contrast, with reference to Figure 13, each resonance attenuating elements 5 is according to a second embodiment of the present invention got involved the part of the first or second section 4a or the contact-making surface between 4b and the object 3 of corresponding impact-absorbing element 4.
This means that in a second embodiment, each impact-absorbing element 4 directly contacts with object 3 parts.Therefore, get involved the structure of the entire contact surface between first and second sections 4a, the 4b of objects 3 and impact-absorbing element 4 with the attenuating elements 5 of wherein resonating and compare, the shock and vibration in the resonance frequency scope of object 3 are bigger.Yet; if the object of being protected 3 has complex multilayer as shown in Figure 13; then consider for example to be easier to install resonance attenuating elements 5, resonance attenuating elements 5 only can be placed in the part of the contact-making surface between first and second sections 4a, the 4b of object 3 and impact-absorbing element 4.
Described below is the actual tests of carrying out according to the effect of the resonance attenuating elements 5 of second embodiment at being used to test.
With reference to Figure 14, each resonance attenuating elements 42 is to be 45g/m by thickness T 1 for 0.15mm and weight
2The band of chemical adhesion non-weaving cloth form.Resonance attenuating elements 42 uses the two-sided tape 43 of the thickness T 2 with 0.05mm to adhere to the upper and lower surface of extention 41.Provide first section 40a thickness T 31.85mm of each impact-absorbing element 40, provide the thickness T 41.75mm of second section 40b.Provide the gross thickness T66.9mm of content playback unit 11, and the thickness T 5 that provides each extention 41 is 3.3mm.
Figure 15 show as with the content playback unit that is not equipped with resonance attenuating elements 42 of the comparative example of according to a second embodiment of the present invention content playback unit 11.In the content playback unit of this comparative example, provide the thickness T 32.2mm of first section 40a of each impact-absorbing element 40, provide the thickness T 42.1mm of second section 40b.Provide the gross thickness T67.6mm of the content playback unit of this comparative example, and provide the thickness T 53.3mm of each extention 41.Other configuration of this content playback unit is basic identical with the configuration according to the content playback unit 11 of second embodiment shown in Figure 14.
Figure 16 illustrates the impact of being obtained according to the content playback unit 11 of second embodiment in being in operator scheme or the curve chart of vibration characteristics when the predetermined altitude of for example 16cm falls down.In Figure 16, the dotted line indication is not equipped with the oscilating characteristic of the content playback unit of resonance attenuating elements 42, and the solid line indication is equipped with the oscilating characteristic according to the content playback unit 11 of the resonance attenuating elements 42 of second embodiment.With the solid line contrast among Figure 11 of the characteristic of suffered impact value of the magnetic head unit 37 that content playback unit 11 in the perfect condition is shown and amplitude, the vibration characteristics that Figure 16 is obtained when showing when actual dropping for example content playback unit 11.As from the comparison between two impact characteristics curves, obviously the impact value in the resonance frequency scope (that is, 1KHz is to 3KHz) of magnetic head unit 37 is lower in the content playback unit 11 of outfit resonance attenuating elements 42 according to a second embodiment of the present invention.The reason that impact value is lower is that owing to be used as the non-weaving cloth of resonance attenuating elements 42, content playback unit 11 can at utmost absorb the high-frequency range of frequency shifting to 1KHz to 3KHz of shock and vibration.The vibration of 1KHz in the scope (that is, the resonance frequency scope of magnetic head unit 37) of 3KHz owing to decayed, so reduced the resonance of magnetic head unit 37.Thereby this prevents magnetic head unit 37 bump storage mediums 36, prevents that also magnetic head unit 37 is owing to the vibration of himself damages.

And, although the resonance frequency of object 3 can comprise, the resonance frequency of the shell of content playback unit 11 for example, the resonance frequency among the above embodiment is the resonance frequency at magnetic head unit 37, latter's influence is for the read and write operation of hard disk.
And although above embodiment is the example at portable audio player, above embodiment also can be applicable to the convention transcriber, such as the DVD player and the audio devices that are equipped with hard disk.
Use resonance attenuating elements 5 to be used for preventing the situation of the displacement of impact-absorbing element 4 therein, the upper and lower major surfaces 3a and the 3b of object 3 can be equipped with coarse part.By allowing impact-absorbing element 4 contact, can under resonating the situation of attenuating elements 5, use not prevent that impact-absorbing element 40 from being the displacement of the object 3 protected with respect to hard disk drive 35 with this coarse part.
And, although in above embodiment, settle impact-absorbing element 40 and resonance attenuating elements 42 so that clamp hard disk drive 35, but impact-absorbing element 40 and resonance attenuating elements 42 replacedly only provide on one of them of the upper and lower major surfaces of hard disk drive 35 from the upper and lower major surfaces of hard disk drive 35.
In vibration-shock absorbing mechanism according to the embodiments of the present invention, between impact-absorbing element and the object of being protected, have decay be in the frequency range that absorbed with impact-absorbing element vibration in the different frequency range or the resonance attenuating elements of impact.Thereby the resonance of object can be reduced by the resonance attenuating elements.And, because the frictional force that generates between resonance attenuating elements and impact-absorbing element can prevent that impact-absorbing element from leaving the object displacement.And as mentioned above, impact-absorbing element and resonance attenuating elements are clamped object from the upper and lower major surfaces of object.And the resonance attenuating elements is positioned at least in one of them of the bottom major surface of the top major surface of object and space between the impact-absorbing element and object and the space between the impact-absorbing element at least.Thereby this has reduced the possibility of impact-absorbing element from the upper and lower major surfaces of object both or first type surface one of them displacement effectively.
In the content playback unit according to above embodiment, impact-absorbing element and resonance attenuating elements protection equipment (that is the object of being protected) are avoided vibration and are impacted.Particularly, owing to the resonance attenuating elements is made of the vibration in the resonance frequency scope of relaxation equipment and the material of impact, so when content playback unit is vibrated or impact, vibration and impact in the resonance frequency scope that is in this equipment that can decay.And, because impact-absorbing element and resonance attenuating elements are positioned on both or one of them of upper and lower major surfaces of the equipment of being protected, therefore can prevent impact-absorbing element both or one of them displacement from the upper and lower major surfaces of this equipment effectively.
And in the content playback unit according to above embodiment, the second low section of impact-absorbing element is relative with the sensing element on the storage medium.Thereby,, therefore can protect sensing element safely because impact-absorbing element can absorb the impact that is applied on the direction of sensing element bump storage medium effectively.
And, the display part towards on drop in the situation of content playback unit, the second low section of the impact-absorbing element of settling away from the display part is subjected to impacting greatly than first epimere of the impact-absorbing element of more settling near the display part.In this case, the second low section may be shifted.Yet, clamp first and second sections of impact-absorbing element from the upper and lower major surfaces of this equipment, be mounted with the resonance attenuating elements between the second low section of the impact-absorbing element of settling away from the display part and the respective major surface of this equipment.Thereby, prevented that impact-absorbing element from leaving the equipment displacement.
And, owing to can for example can on hard disk drive, carry out suitable reproduction operation by the effective attenuation of resonance attenuating elements in response to the resonance of vibrating or impact the hard disk drive that generates.And, also can prevent the accident deletion that causes by vibration or impact to data.
