Wherein, the frame size of the optical disc mounting frame for testing is 200 mm in depth and 640 mm in width, and the scattering property test is performed by using the structure of the partitioning member 2 of the second embodiment of the present invention, and the size of the partitioning member 2 is the bonding portion 21 to The depth of the first abutting surface 222a is 25 mm; the depth of the joint portion 21 to the second abutting surface 222b is 55 mm. The width (W) of the first abutting surface 222a and the second abutting surface 222b is 40 mm. The invention uses a non-directional speaker as a test sound source to avoid unnecessary interference and affect test results. Sound energy in a generally good listening space should be non-directional and evenly distributed throughout the listening Position, scattering coefficient s measurement focus on the reverberation chamber does not consider the directivity of the reflected sound energy, but the random incidence of the non-directional sound source as the source of sound energy, the measured data is more comprehensive, therefore, According to the present invention, the change in the area of the storage case 3 caused by the shape of the partition plate 2 and the change in the area of the storage case 3 are corresponding to the change in the scattering performance, and the scattering coefficient is used as the evaluation basis.
請參照第7圖所示，藉由聆聽室聲場電腦模擬分析獲得較佳之收納盒3配置比例。比較收納盒3置入率分別為100%、80%、50%、20%、0%時之散射性能，由圖所示，如要取得頻帶範圍較廣的散射係數就必須增加收納盒3置入量，從50%、80%及100%的散射係數變化可以看到於200至1k Hz頻帶範圍的落差，當收納盒3在光碟置放架上配置的位置越均勻，影響的頻帶也就越高和越廣，不同之收納盒3置入率在隨機入射吸音係數方面則會產生與散射係數相對之變化，該收納盒3置入率越高其散射效果越明顯，但隨機入射吸音係數則降低。本發明較佳係將該收納盒3依序置入，依序置入方式較接近傳統擴散板的散射效果。本發明光碟置放架之散射係數測試在中低(250~500 Hz)及中高頻(630~1.6k Hz)平均產生高於0.5之散射效果。當該收納盒3置入率為100%時，在400及500 Hz兩個中心頻率分別產生最佳散射效果為0.88及0.85，此結果與構造變化為主之聲學擴散板之散射效果近似，證明本發明之光碟置放架具有擴散板的功能。此外，本發明光碟置放架之收納盒3置入率為100%時，形成之擴散面可達到最佳之散射效果。Please refer to Fig. 7 to obtain a better configuration ratio of the storage box 3 by computer simulation analysis of the sound field of the listening room. Comparing the scattering performance when the insertion rate of the storage box 3 is 100%, 80%, 50%, 20%, and 0%, respectively, as shown in the figure, if the scattering coefficient of a wide frequency band is to be obtained, the storage box 3 must be added. The variation of the scattering coefficient from 50%, 80% and 100% can be seen in the range of 200 to 1k Hz. When the storage box 3 is placed on the disc rack, the more uniform the frequency band is. The higher and wider, the different insertion rate of the storage box 3 will produce a change with respect to the scattering coefficient in terms of the random incident sound absorption coefficient. The higher the insertion rate of the storage box 3, the more obvious the scattering effect, but the random incidence sound absorption coefficient. Then lower. In the present invention, the storage box 3 is preferably placed in sequence, and the sequential placement method is closer to the scattering effect of the conventional diffusion plate. The scattering coefficient test of the optical disc placement frame of the present invention produces an average scattering effect of more than 0.5 at medium to low (250 to 500 Hz) and medium and high frequency (630 to 1.6 k Hz). When the insertion rate of the storage box 3 is 100%, the optimal scattering effects are 0.88 and 0.85 at the two center frequencies of 400 and 500 Hz, respectively, and the result is similar to the scattering effect of the acoustic diffusion plate whose structure is dominant. The disc placement rack of the present invention has the function of a diffuser. In addition, when the insertion rate of the storage box 3 of the optical disc placement rack of the present invention is 100%, the formed diffusion surface can achieve an optimum scattering effect.
請參照第8圖所示，本發明之光碟置放架收納盒3置入率對隨機入射散射與吸音係數之影響，以擴散板的設計規範來說應是要以整塊板材的散射係數皆大於0.5為基準，然而本發明之光碟置放架乃實際使用之生活產品，其使用配置的方式不同就會在擴散面結構上產生變化，隨著使用者使用的時間越長所置入的收納盒3數量就越多。但排序與結構變化的現象則是相反，當收納盒3置入率在0%與100%時的變化是最少的，因為其結構變化範圍已達到極限。置入率50%~80%時剩餘空間仍足夠做排序變化，但較佳為依序均勻置入。如圖所示，置入率愈高散射能力愈佳，吸音能力愈低。Please refer to FIG. 8 , the influence of the insertion rate of the optical disc storage rack storage box 3 on the random incident scattering and the sound absorption coefficient, and the scattering coefficient of the whole plate should be the design specification of the diffusion plate. More than 0.5 is the benchmark. However, the optical disc placement rack of the present invention is a living product that is actually used, and the configuration of the dispersing surface is different in the configuration of the diffusing surface, and the storage box placed with the user is used for a longer period of time. 3 The more the number. However, the phenomenon of sorting and structural change is the opposite. When the insertion rate of the storage box 3 is 0% and 100%, the change is the smallest because the structural variation range has reached the limit. When the placement rate is 50%~80%, the remaining space is still enough to make sorting changes, but it is better to place them evenly. As shown in the figure, the higher the placement rate, the better the scattering ability and the lower the sound absorption capability.
此外，藉由電腦模擬環境針對空室與置入本發明光碟置放架對測試聆聽室之總聲能聲壓位準(Total sound pressure level,T-SPL)及30 dB外推迴響時間(T30 )之影響做比較。本發明係藉由EASE聲學模擬軟體，測試室內環境材料對本發明光碟置放架的影響。請參照第9圖所示，電腦模擬模型之室內壁面均以清水混凝土為主，第A組為空室，第B組為於空室中置入本發明光碟置放架。由圖中之總聲能聲壓位準(T-SPL)可知，置入光碟置放架後的聲場自250 Hz起有7 dB的最大衰減，而在1k Hz也出現約3 dB的衰減值，顯示光碟置放架在頻帶範圍250~1k Hz有最佳散射性能，能發揮其控制聲場的特性。另，請參照第10圖所示，電腦模擬模型之室內壁面均以木絲水泥板為主，第C組為空室，第D組為於空室中置入本發明光碟置放架。由圖可知，500 Hz至4k Hz的頻帶範圍由90 dB衰 減至80 dB以下。置入光碟置放架後的聲場由於其構造所產生的吸音又消耗掉部份聲能，所以高頻4k Hz之總聲能聲壓位準衰減至約75 dB左右，同樣在250 Hz與1k Hz的差異量最大。由圖可知，藉由於空室中置入本發明光碟置放架，可提升散射性能，有助於改善聆聽室內聲壓之均勻分佈性。In addition, the total sound pressure level (T-SPL) and the 30 dB extrapolated reverberation time (T) of the test listening room are determined by the computer simulation environment for the empty room and the optical disc placement frame of the present invention. 30 ) The impact is compared. The present invention tests the influence of indoor environmental materials on the optical disc placement rack of the present invention by means of an EASE acoustic simulation software. Referring to Figure 9, the indoor wall of the computer simulation model is mainly made of clear water concrete, the first group is an empty room, and the second group is the optical disc placement frame of the present invention. From the total sound energy sound pressure level (T-SPL) in the figure, the sound field after being placed in the disc rack has a maximum attenuation of 7 dB from 250 Hz, and about 3 dB attenuation at 1 k Hz. The value shows that the disc placement rack has the best scattering performance in the frequency range of 250~1k Hz, and can exert its characteristics of controlling the sound field. In addition, please refer to Fig. 10, the indoor wall surface of the computer simulation model is mainly wood wool cement board, the first group C is an empty room, and the fourth group is the optical disc placement frame of the invention placed in the empty room. As can be seen from the figure, the frequency range from 500 Hz to 4 k Hz is attenuated from 90 dB to less than 80 dB. The sound field after being placed in the disc placement rack consumes part of the sound energy due to the sound absorption generated by its structure, so the total sound energy level of the high frequency 4k Hz is attenuated to about 75 dB, also at 250 Hz. The difference in 1k Hz is the largest. It can be seen from the figure that the scattering performance can be improved by inserting the optical disc placement frame of the present invention into the empty chamber, which helps to improve the uniform distribution of the sound pressure in the listening room.
請參照第11及12圖所示，為不同材質空室置入本發明光碟置放架前後之迴響時間(T30 )比較。如第11圖所示，電腦模擬模型之室內壁面均以清水混凝土為主，第A組為空室，第B組為於空室中置入本發明光碟置放架。本發明之光碟置放架置入率為100%。由圖可知，在中低頻帶100~500 Hz頻帶範圍能有效控制低頻迴響時間過高的情況，從500 Hz前的低頻範圍可看到空室的迴響時間皆高於2.5秒，透過光碟置放架置入空室使迴響時間可控制於2至2.5秒之間，使音樂於各頻率的表現均齊且完整，藉由本發明之光碟置放架可改善室內之聲學效果。另，請參照第12圖所示，電腦模擬模型之室內壁面均以木絲水泥板為主，第C組為空室，第D組為於空室中置入本發明光碟置放架，光碟置放架置入率為100%。如圖所示，在中低頻帶100~250 Hz頻帶範圍將迴響時間由2秒降低至1.5秒以下，而500 Hz以上因木絲水泥板吸音力衰減使迴響時間降至0.5秒以下，在置入本發明之光碟置放架後可因其散射的特性提高迴響時間，使聆聽室的高頻迴響時間維持在0.5至1秒之間，使各頻率間的迴響時間較一致，進而提升聲場均勻性，讓原本因為木絲水泥板吸音力所產生之乾澀 感獲得改善。由空室與置入本發明之光碟置放架模擬條件比對結果顯示，可藉由置入本發明之光碟置放架來降低迴響時間之差異，使各頻率在音樂效果上獲得較均齊之感受度。Referring to Figures 11 and 12, the reverberation time (T 30 ) of the different material empty chambers before and after the placement of the optical disc placement rack of the present invention is compared. As shown in Fig. 11, the indoor wall surface of the computer simulation model is mainly made of clear water concrete, the first group is an empty chamber, and the second group is the optical disc placement frame of the present invention placed in the empty chamber. The disc placement rate of the present invention is 100%. It can be seen from the figure that in the low-frequency band of 100~500 Hz, the low-frequency reverberation time can be effectively controlled. From the low-frequency range before 500 Hz, it can be seen that the reverberation time of the empty room is higher than 2.5 seconds. The placement of the empty chamber allows the reverberation time to be controlled between 2 and 2.5 seconds, so that the performance of the music at each frequency is uniform and complete, and the acoustic arrangement of the present invention can be improved by the optical disc placement rack of the present invention. In addition, please refer to Figure 12, the indoor wall surface of the computer simulation model is mainly wood wool cement board, the first group is empty room, the first group is the optical disc placement frame, optical disc placed in the empty room. The placement rate of the rack is 100%. As shown in the figure, the reverberation time is reduced from 2 seconds to less than 1.5 seconds in the low-frequency band of 100~250 Hz, and the reverberation time is reduced to less than 0.5 second due to the attenuation of the sound absorption of the wood-cement cement board above 500 Hz. After the optical disc placement frame of the invention, the reverberation time can be improved due to the scattering characteristics, and the high frequency reverberation time of the listening room is maintained between 0.5 and 1 second, so that the reverberation time between the frequencies is relatively uniform, thereby improving the sound field. The uniformity improves the dryness caused by the sound absorption of the wood wool cement board. The comparison result between the empty chamber and the optical disc placement frame of the present invention shows that the difference in reverberation time can be reduced by placing the optical disc placement frame of the present invention, so that the frequencies are more uniform in the music effect. Feelings.

For the comparison of the range (2k to 5k Hz), the storage box 3 is placed at a rate of 100%. Group E is a conventional QRD diffuser; Group F is a disc placement rack of the present invention. The scattering effect of the E group and the scattering effect of the F group are in a reverse trend in the trend of the scattering coefficient. The optical disc placement frame of the present invention has a better scattering effect in the middle, low, and high frequency bands, and the QRD is used. The diffuser plate gradually increases its scattering coefficient from low frequency to high frequency. The results show that the scattering performance of the disc placement frame of the present invention has a similar scattering effect as the QRD diffusion plate. The optical disc placement rack of the present invention has a storage function, and the structure of the entire optical disc placement rack is different in depth by the ordering change of the position of the storage storage case 3, thereby achieving an effect similar to that of the diffusion plate. The optical disc placement frame of the invention has the function of combining with the function and the multi-function, and has high combination, and the user can make various changes according to the requirements, thereby improving the uniform distribution of the sound pressure in the listening room and achieving a uniform sound field.
