具体实施方式第一实施例 DETAILED DESCRIPTION Example embodiments of the first embodiment

图3是根据本发明的第一实施例的振动冲击吸收机构1的横断面视图。 FIG 3 is a cross sectional view of an impact absorbing mechanism according to an embodiment of the vibration of the first embodiment of the present invention. 振动冲击吸收机构1包括外壳2、冲击吸收元件4和共振衰减元件5。 Vibration impact absorbing mechanism 1 comprises a housing 2, shock absorbing member 4 and the resonance damping member 5. 冲击吸收元件4 被安置在外壳2与安置在外壳2内部将被保护的物体3之间。 The shock absorbing element is arranged in the housing 2 to be protected and disposed in the interior of the housing 2 between the object 4 3. 共振衰减元件5由具有与冲击吸收元件4不同的振动衰减特性的材料构成,它被安置在物体3与冲击吸收元件4之间。 Materials resonance damping element 54 different vibration damping characteristics of the shock absorbing member having a configuration, which is disposed between the object 3 and the shock absorbing member 4.

每一冲击吸收元件4在横断面中基本上是C形的,且它具有一对第一上段4a 和第二下段4b、以及连接第一和第二段4a和4b的第三中段4c。 Each shock absorbing member 4 is substantially C-shaped in cross-section, and having a pair of a first upper segment 4a and second lower segment 4b, and connecting first and second segments 4a and 4b of the middle third 4c. 冲击吸收元件4 按照第一和第二段4a和4b分别从物体3的上下主表面3a和3b部分地夹住物体3 来附加到物体3的左侧和右侧。 Shock absorbing member 4 according to the first and second segments 4a and 4b respectively, from upper and lower main surfaces 3a and 3b of the object 3 clamped portion 3 to attach the object to the left and right sides of the object 3. 而且,冲击吸收元件4由诸如橡胶和合成橡胶的弹性材料构成。 Further, the shock absorbing member 4 is made of an elastic material such as rubber and synthetic rubber.

共振衰减元件5被附加到上和下主表面3a和3b的诸部分,其中在冲击吸收元件4的第一和第二段4a和4b的内表面之间夹住物体3。 Damping the resonance element 5 is attached to the upper and lower main surfaces 3a and 3b of portions, wherein the object 3 sandwiched between the first and second segments 4a and 4b of the inner surface of the shock absorbing element. 因此,冲击吸收元件4 的第一和第二段4a和4b的内表面在没有与上下主表面3a和3b直接接触的情况下经由共振衰减元件5夹住物体3。 Thus, the shock absorbing element sandwiched between a first object and a second section 5 and the inner surfaces 4a and 4b via the resonance damping element in the absence of direct contact with the upper and lower main surfaces 3a and 3b 3 4 in.

共振衰减元件5由制成片或条的通常所说的非织造布构成。 5 is constituted by the resonance damping element is made of sheet or strip-called nonwovens. 将在此处简要地 Will briefly here

描述非织造布。 Description of non-woven cloth. 非织造布通过机械地缠结纤维或通过化学或使用热量来处理纤维形成。 Nonwoven fabric fibers be treated by the use of heat or chemical formed by mechanically entangling fibers or. 与此相反, 一般的纺织品和针织物是使用线或纱的织物,它们通过对一组纤维进行纺纱或捻线来形成,并通过使用例如织布机或针织设备的复杂加工来制成。 In contrast, general textiles and knit fabrics using yarn or wire, which is formed by a group of fibers on spinning or twisting, and be made by using the complex machining, for example, a loom or knitting device. 取决于不同的制造工艺,非织造布可分为各种组,包括例如,热轧(thermal bond) 非织造布、针剌(needle punch)非织造布、水刺(spun lace)非织造布和化学粘合(chemicalbond)非织造布。 Depending on the manufacturing process, the nonwoven fabric can be divided into various groups, including, for example, hot rolling (thermal bond) nonwoven fabric, needled (needle punch) nonwoven, hydroentangled (spun lace) and nonwoven fabric chemical bonding (chemicalbond) nonwoven fabric. 具体地,化学粘合非织造布通过经由浸渍、喷射或起泡将粘合树脂应用于纤维来使得纤维的缠结点(intertwiningpoint)粘附在一起, 然后对纤维加热来形成。 In particular, chemical bonded nonwoven fabric via impregnation, spraying or foaming the binder resin to be such that the fibers entangled points of the fibers (intertwiningpoint) adhered together, and then heated to form a fiber. 因此,化学粘合非织造布能以相对的低成本制造,因此适用作共振衰减元件5。 Accordingly, the chemical bonded nonwoven fabric can be manufactured at relatively low cost, and therefore suitable as the resonance damping element 5.

在第一实施例中,如图3中所示,每一共振衰减元件5介入相应的冲击吸收元件4的第一或第二段4a或4b与所保护的物体3之间的整个接触面。 In a first embodiment, shown in Figure 3, each of the resonance damping element 5 intervention respective shock absorbing element of the first or second segment 4a or 4b 4 and protected the entire contact surface between the object 3. 与此相反, 参考图13,根据本发明的第二实施例的每一共振衰减元件5介入相应的冲击吸收元件4的第一或第二段4a或4b与物体3之间的接触面的一部分。 In contrast to this part, referring to FIG. 13, according to each of the intervention corresponding impact of the resonance of the second embodiment of the present invention, the damping element 5 between the first or second segment 4a or 4b 4 and the absorbent body 3 of the contact surface element .

这意味着,在第二实施例中,每一冲击吸收元件4与物体3部分直接接触。 This means that, in the second embodiment, each of the shock absorbing member 4 in direct contact with the object 3 portions. 因此,与其中共振衰减元件5介入物体3与冲击吸收元件4的第一和第二段4a、 4b之间的整个接触面的结构相比,物体3的共振频率范围中的冲击和振动更大。 Accordingly, the resonance damping element and wherein the intervening structure of the entire contact surface 5 of the object 3 and the shock absorbing member 4 between the first and second segments 4a, 4b compared, the greater the resonance frequency range of the object 3 of shock and vibration . 然而,如果所保护的物体3具有如图13中所示的复杂多层结构,则考虑到例如更易于安装共振衰减元件5,可将共振衰减元件5仅安置在物体3与冲击吸收元件4 的第一和第二段4a、 4b之间的接触面的一部分中。 However, if the protected object 3 has a complex multilayer structure shown in FIG. 13, for example, is considered easier to install the resonance damping element 5, the resonance damping element 5 may be disposed only on the object 3 and the shock absorbing member 4 part of the contact surface between the first and second segments 4a, 4b of.

以下描述的是针对用于测试根据第二实施例的共振衰减元件5的效果而进行的实际试验。 The following describes the practical tests conducted for testing for the effect of the resonance element 5 according to a second embodiment of attenuation.

图15示出了作为与根据本发明的第二实施例的内容再现装置11的比较示例的未配备共振衰减元件42的内容再现装置。 Figure 15 shows a content based on the content of the second embodiment of the present invention, the reproducing apparatus 11 of the comparative example not provided with the resonance damping element 42 of the reproducing apparatus. 在该比较示例的内容再现装置中,给出每一冲击吸收元件40的第一段40a的厚度T3 2.2mm,给出第二段40b的厚度T4 2.1mm。 In the content reproducing apparatus of the comparative example, the shock absorbing element is given for each of first section 40a of a thickness of 40 T3 2.2mm, the thickness of the second segment 40b is given a T4 2.1mm. 给出该比较示例的内容再现装置的总厚度T6 7.6mm,而给出每一附加部分41的厚度T5 3.3mm。 The total thickness of the comparative example is given content reproducing apparatus T6 7.6mm, given the thickness of each additional portion 41 of T5 3.3mm. 该内容再现装置的其它配置与根据图14中所示的第二实施例的内容再现装置11的配置基本相同。 Other configurations of the content reproducing apparatus the contents of the second embodiment is substantially the same with the embodiment shown in FIG. 14 according to the reproducing apparatus 11 is disposed.

图16是示出当处于操作模式中的根据第二实施例的内容再现装置11从例如16 cm的预定髙度掉下时所获取的冲击或振动特性的曲线图。 FIG 16 is a view showing the mode of operation in accordance with a second embodiment of the reproducing apparatus of the embodiment of FIG. 11 from a graph such as impact Gao predetermined degree of fall 16 cm or acquired vibration characteristics. 在图16中,虚线指示未配备共振衰减元件42的内容再现装置的振动特性曲线,实线指示配备根据第二实施例的共振衰减元件42的内容再现装置11的振动特性曲线。 In FIG. 16, a broken line indicates the resonance characteristic is not equipped with the vibration damping element content reproducing apparatus 42, the solid line indicates the characteristic curve in accordance with the contents of the resonance oscillation of the second embodiment of the damping element 42 of the reproducing apparatus 11. 与示出理想状态中内容再现装置11的磁头单元37所受到的冲击值和振幅的特性的图11中的实线对比,图16示出了当例如实际掉落时内容再现装置11时所获取的振动特性。 The solid line 11 in FIG comparative impact value and an amplitude characteristic of the magnetic head unit 37 is subjected to the ideal state shown in the content reproduction apparatus 11, FIG. 16 shows an example when the actual drop the content reproduction apparatus 11 acquired the vibration characteristics. 正如从两条冲击特性曲线之间的比较,显然磁头单元37的共振频率范围(即,lKHz 到3KHz)中的冲击值在配备根据本发明的第二实施例的共振衰减元件42的内容再现装置11中较低。 As comparison between the two shock characteristic curves, the resonance frequency range is clearly the impact value (i.e., lkHz to 3KHz) the head unit 37 in the content reproducing apparatus equipped with a second embodiment of the resonator of the present invention, the damping element 42 lower 11. 冲击值较低的原因是,由于用作共振衰减元件42的非织造布, 内容再现装置11可最大程度吸收冲击和振动的频率位移至1 KHz到3 KHz的高频范围。 The reasons for the low impact value, since the nonwoven fabric used as the resonance damping element 42, the content reproduction apparatus 11 can maximize the impact and vibration absorption frequency position is moved to a high frequency range of 1 KHz to 3 KHz. 由于衰减了lKHz到3KHz的范围(g卩,磁头单元37的共振频率范围)中的振动,因此减少了磁头单元37的共振。 Since the attenuation range to 3KHz lKHz vibration (resonance frequency range g Jie, the head unit 37) in, thus reducing the resonance of the head unit 37. 从而,这防止磁头单元37撞击存储介质36,也防止磁头单元37由于其自身的振动而损坏。 In turn, this prevents the head unit 37 striking the storage medium 36 and also prevents the head unit 37 due to its own vibration damage.

在其中未使用共振衰减元件5用于防止冲击吸收元件4的移位的情况中,物体3的上下主表面3a和3b可装有粗糙部分。 In the case of member 5 for preventing displacement of the shock absorbing member 4 which is not a resonance damping, the upper and lower main surfaces 3a and 3b of the object 3 may be provided with a roughness. 通过允许冲击吸收元件4与该粗糙部分接触,可在未使用共振衰减元件5的情况下防止冲击吸收元件40相对于硬盘驱动器35即所保护的物体3的移位。 By allowing the shock absorbing member 4 is in contact with the roughened portion, may be used without resonance dampening member 5 to prevent the case 40 of the impact absorbing member for shifting the hard disk drive 35 that is protected object 3.

而且,尽管在以上实施例中,安置冲击吸收元件40和共振衰减元件42以便从硬盘驱动器35的上下主表面夹住硬盘驱动器35,但冲击吸收元件40和共振衰减元件42可替换地仅在硬盘驱动器35的上下主表面的其中之一上提供。 Furthermore, although in the above embodiment, the placement of the shock absorbing member 40 and the resonance damping element 42 so as to sandwich a hard disk drive 35 from the upper and lower major surfaces of the hard disk drive 35, but the shock absorbing member 40 and the resonance damping element 42 may alternatively be only the hard disk wherein one of the upper and lower main surface of the driver 35 is provided.

在根据本发明的以上实施例的振动冲击吸收机构中,在冲击吸收元件与所保护的物体之间具有衰减处于与冲击吸收元件所吸收的频率范围所不同的频率范围中的振动或冲击的共振衰减元件。 In the shock and vibration according to an embodiment of the present invention, the above absorption mechanism, having a shock absorbing attenuation in different frequency ranges in the absorption of the shock absorbing element or shock vibration frequency range between the resonance element and the protected object damping element. 从而,物体的共振可由共振衰减元件减少。 Thus, the resonance of the object can be reduced resonance damping element. 而且, 由于在共振衰减元件与冲击吸收元件之间生成的摩擦力,可防止冲击吸收元件离开物体移位。 Further, since the frictional force generated between the elements and the shock absorbing element in the resonant attenuation to prevent a shift shock absorbing member away from the object. 而且,如上所述,冲击吸收元件和共振衰减元件从物体的上下主表面夹住物体。 Further, as described above, the shock absorbing element sandwiched between the object and the resonance damping element from the upper and lower main surface of the object. 而且,共振衰减元件至少被安置在物体的上主表面与冲击吸收元件之间的空间和物体的下主表面与冲击吸收元件之间的空间的至少其中之一内。 Wherein at least one of a space between the inner member and the lower main surface of the impact, the resonance damping element is arranged at least on the main surface of the object and the shock absorbing space between the object and the absorption element. 从而,这有效地减少了冲击吸收元件从物体的上下主表面两者或主表面其中之一移位的可能性。 Accordingly, this effectively reduces the possibility of shock absorbing member from the upper and lower main surface of the object or both the main surface of one of the shift.

在根据以上实施例的内容再现装置中,冲击吸收元件和共振衰减元件保护设备(即,所保护的物体)免受振动和冲击。 Content according to the above embodiment of the reproducing apparatus, the shock-absorbing element and the resonance damping element protection devices (i.e., protected object) from vibration and shock. 具体地,由于共振衰减元件由衰减设备的共振频率范围中的振动和冲击的材料构成,因此当内容再现装置受到振动或冲击时,可衰减处于该设备的共振频率范围中的振动和冲击。 In particular, the resonance damping element made of a material damping in the resonance frequency range of the equipment vibration and shock, and thus when the content reproducing apparatus is subjected to vibration or shock can be attenuated in the resonant frequency range of the apparatus vibrations and shocks. 而且,由于冲击吸收元件和共振衰减元件被安置在所保护的设备的上下主表面的两者或其中之一上,因此可有效地防止冲击吸收元件从该设备的上下主表面中的两者或其中之一移位。 Further, since the shock absorbing element and resonance damping device is placed in both the main surface of the protection member, or on one of the vertical, it can be effectively prevented from both the upper and lower major surfaces of the device or shock absorbing elements one of displacement.

而且,在根据以上实施例的内容再现装置中,冲击吸收元件的第二低段与存储介质上的读出单元相对。 Also, the content of the embodiment according to the above reproduction apparatus, the read unit relative to the second segment and low shock absorbing element storage medium. 从而,由于冲击吸收元件可有效地吸收读出单元撞击存储介质的方向上所施加的冲击,因此可安全地保护读出单元。 Thus, since the shock absorbing member can effectively absorb shock readout direction unit hits against the applied storage medium, the reading unit may be so protected safely.

而且,在显示部分面向上掉落内容再现装置的情况中,远离显示部分安置的冲击吸收元件的第二低段受到比更接近显示部分安置的冲击吸收元件的第一上段更大程度的冲击。 Further, in the case of the display portion facing the drop in the content playback apparatus, the second low stage away from the display portion of the impact absorbing member being disposed on a first section of a greater degree of impact shock absorbing portion is disposed closer than the display element. 在这种情况中,第二低段可能移位。 In this case, the second lower segments may be shifted. 然而,在从该设备的上下主表面夹住冲击吸收元件的第一和第二段中,远离显示部分安置的冲击吸收元件的第二低段与该设备的相应主表面之间安置有共振衰减元件。 However, in the shock absorbing element sandwiched between the upper and lower main surfaces of the first and second segments of the apparatus, there is disposed away from the display between the respective main surface of the second portion of the low stage shock absorbing member disposed with the resonance damping device element. 从而,防止了冲击吸收元件离开设备移位。 Thus, the impact absorbing member is prevented from shifting away from the device.

而且,由于响应于振动或冲击生成的硬盘驱动器的共振可由共振衰减元件有效衰减,例如可在硬盘驱动器上执行适当的再现操作。 Further, since the response to a vibration or shock generated by the hard drive of the resonance damping element effective resonant attenuation, for example, perform an appropriate reproduction operation on the hard drive. 而且,也可防止由振动或冲击引起的对数据的意外删除。 Moreover, it prevents accidental data caused by vibration or shock deleted.
