Thereby, the sound absorbing tips 140 laid in the soundproof housing 112 and the chambers 112a to 112e can generate sound absorbing effects to reduce the interference of the environmental noise outside the audio testing system 100 to the product to be tested 102.

Furthermore, in the present embodiment, in addition to the sound absorbing tip 140, the soundproof housing 112 of the soundproof box 100 is further provided with a plurality of sound absorbing cottons 150, which also have a sound absorbing effect. In detail, in the present embodiment, the soundproof housing 112 further includes a plurality of partitions 160. The sound insulating case 112 has a partition 160 as an inner wall and forms a space 118 with the outer wall of the soundproof case 112, and the sound absorbing cotton 150 is filled in the space 118. More specifically, the spacer 160 includes a plurality of sound-insulating sheets, for example, a perforated plate having a thickness of 5 mm and a perforation rate of 50%, but the invention is not limited thereto. Thereby, the partition 160 itself has a sound absorbing effect, and the partition 160 is spaced apart from the bottom portion of the sound insulating housing 112 by a space 118 between the partition 160 and the outer wall of the soundproof housing 112. The partition 160 can be considered to be the inner wall of the soundproof housing 112. At this time, the sound absorbing cotton 150 is filled in the space 118, and part of the sound absorbing tip 140 can be further laid on the partition 160 (ie, the inner wall of the soundproof case 112).

Among them, the conveyor belt 120 can adopt a silent conveyor belt to avoid noise when transmitting the product to be tested 102. Thereby, the conveyor belt 120 can be connected to the device required before or after the test step (for example, assembly), and automatically transports the product to be tested 102 to the soundproof box 110 through the same conveyor belt 120 for testing, without being tested here. In the step, the product to be tested 102 is delivered by human power.

Further, when the product to be tested 102 is finished at the previous step of the production line, it can be transferred to the soundproof box 110 by the conveyor belt 120 for audio testing. Wherein, the conveyor belt 120 transfers the product to be tested 102 from the inlet 119a to the soundproof box body 112 of the soundproof box 110, and stops the transmission when the product to be tested 102 corresponds to the chamber 112c, so that the product to be tested 102 corresponds to the chamber 112c and the setting Test element 130 within chamber 112c. In this manner, the product to be tested 102 is subjected to an audio test in the chamber 112c by the test component 130, wherein the sound absorbing tip 140, the sound absorbing cotton 150, and the spacer 160 in the soundproof housing 112 can generate sound absorbing effects, and the cavity located on the outer side. The chambers 112a, 112b, 112d, 112e may provide a sound insulation to reduce interference from the ambient noise outside the audio test system 100 to the product under test 102. After the test is completed, the product to be tested 102 is removed from the exit box 119b by the conveyor belt 120, and the next step on the line is performed. However, the present invention is not limited to the intermediate in the chambers 112a to 112e for testing, which can be adjusted as needed. Thereby, the audio test system 100 can automatically test the audio of the product to be tested 102 and has a good test effect.

2 is a schematic diagram of an audio test system in accordance with another embodiment of the present invention. Referring to FIG. 2, in the present embodiment, the audio test system 200 includes a soundproof box 210, a conveyor belt 220, a test component 230, a sound absorbing tip 240, a sound absorbing cotton 250, and a partition 260. The soundproof box 210 includes a soundproof box body 212 and a tunnel 214 extending through the soundproof box body 212. The soundproof box body 212 is partitioned by a wall body 216 to partition a plurality of adjacent chambers 212a to 212e, and the conveyor belt 220 is disposed in the tunnel. The test element 230 is disposed in one of the chambers 212a to 212e, such as in the middle (i.e., the chamber 212c), through the soundproof housing 212 and corresponding to the positions of the chambers 212a to 212e. Moreover, the sound absorbing tip 240 is laid on the inner wall of the soundproof box 212 and the wall 216 of the chambers 212a to 212e, and the sound absorbing cotton 250 is disposed on the top of the chambers 212a to 212e and filled in the partition 260 and the soundproof box. 212 is within the space 218 between the outer walls. Therefore, the audio test system 200 has a similar structural design to the audio test system 100. Therefore, for the specific implementation of the above components, reference may be made to the description of the previous embodiment, and details are not described herein.

In the present embodiment, the main difference between the audio test system 200 and the aforementioned audio test system 100 is that the conveyor belt 220 of the present embodiment is different from the aforementioned conveyor belt 120. Specifically, in the present embodiment, the inlet 219a and the outlet 219b are disposed on opposite sides of the soundproof box 210, and are substantially at the same level. The tunnel 214 communicates with the inlet 219a and the outlet 219b such that the conveyor belt 220 passing through the tunnel 214 extends from the inlet 219a toward the outlet 219b. In addition, the conveyor belt 220 has a recessed portion 222. The level of the recess 222 is lower than the level of the entrance 219a and the outlet 219b of the tunnel 214 through the soundproof enclosure 212, and the recess 222 corresponds to one of the chambers 212a to 212e. More specifically, the chamber corresponding to the recess 222 is located in the middle of the chambers 212a to 212e (ie, the chamber 212c). In other words, the conveyor belt 220 corresponds to a portion of the middle of the chambers 212a to 212e (i.e., the chamber 212c) that is lower than other portions of the conveyor belt 220 such that it constitutes a recess 222 having a lower level than the inlet 219a and the outlet 219b. Thereby, when the product to be tested 202 is transferred into the soundproof box body 212 by the conveyor belt 220 and corresponds to the chamber 212c and the test element 230 located in the chamber 212c for testing, the product to be tested 202 corresponds to the recessed portion 222. Internally, the lateral noise that enters the sound insulating housing 212 from the inlet 219a and the outlet 219b can be reduced to affect the test of the product 202 to be tested.

In addition, in the present embodiment, the chambers 212a to 212e may be further adjusted in accordance with the design of the recess 222. In detail, in the present embodiment, the chambers 212a to 212e are partitioned by the wall body 216 in the soundproof housing 212. Wherein, the wall body 216 respectively faces the test position of the product to be tested 202, for example, appears to be radial, and corresponds to the recessed portion 222 of the conveyor belt 220. In other words, the wall 216 corresponding to the recess 222 (for example, the middle wall 216) extends toward the recess 222 such that the vertical distance between each wall 216 and the conveyor belt 220 is substantially the same, that is, each chamber 212a There is a similar or consistent distance between the 212e and the conveyor belt 220. Further, since the level of the recessed portion 222 is lower than the level of the inlet 219a and the outlet 219b, the level of the wall 216 extending into the recessed portion 222 is also lower than the level of the inlet 219a and the outlet 219b. Thereby, the chambers 212a to 212e and the conveyor belt 220 are close to each other, so that the product to be tested 202 located in the recess 222 and corresponding to the middle of the chambers 212a to 212e (ie, the chamber 212c) can effectively pass through the chamber 212a to The outer side of the 212e (i.e., the chambers 212a, 212b, 212d, 212e) produces sound insulation and produces sound absorbing by the sound absorbing body 212 and the sound absorbing tips 240, the sound absorbing cotton 250 and the partition 260 in the chambers 212a to 212e. The lateral noise can also be isolated by the outer chambers 212a, 212b, 212d, 212e and the sound absorbing tip 240, thereby reducing the interference of the ambient noise outside the audio test system 200 to the product to be tested 202.

Further, when the product to be tested 202 is finished at the previous step of the production line, it can be transferred to the soundproof box 210 by the conveyor belt 220 for audio testing. Wherein, the conveyor belt 220 transfers the product to be tested 202 from the inlet 219a to the soundproof box 212 of the soundproof box 210, and stops the transmission when the product to be tested 202 corresponds to the chamber 212c, so that the product to be tested 202 corresponds to the chamber 212c and the setting Test element 230 within chamber 212c. In this manner, the product to be tested 202 is subjected to an audio test in the chamber 212c by the test component 230, wherein the sound absorbing tip 240, the sound absorbing cotton 250, and the spacer 260 in the soundproof housing 212 can generate sound absorbing effects, and the cavity located on the outer side. The chambers 212a, 212b, 212d, 212e may provide a soundproofing effect to reduce the interference of the ambient noise outside the audio test system 200 with the product 202 to be tested, for example, within the soundproof box 210 if the ambient noise is 65 decibels (dB). The noise is reduced to 40 decibels, but the invention is not limited thereto. After the test is completed, the product to be tested 202 is removed from the outlet 219b by the conveyor belt 220 and the next step on the production line. However, the present invention is not limited to the intermediate in the chambers 212a to 212e for testing, and does not limit the recess 222 to correspond to the intermediate one of the chambers 212a to 212e, which can be adjusted as needed. Thereby, the audio test system 200 can automatically test the audio of the product to be tested 202 and has a good test effect.

In summary, in the audio test system of the present invention, a plurality of adjacent chambers are partitioned from the soundproof box of the soundproof box, and a plurality of sound absorbing tips, sound absorbing cotton and partitions are disposed in the soundproof box. In addition, the tunnel of the soundproof box runs through the soundproof box, and the conveyor belt passes through the tunnel to pass through the soundproof box. In this way, the product to be tested can be transferred to the soundproof box through the conveyor belt to be tested at a position corresponding to one of the chambers (for example, in the middle). At this time, the other person in the chamber (for example, the outer side) can generate sound insulation, and the sound absorbing tip, the sound absorbing cotton and the partition plate which are laid in the soundproof box can generate sound absorbing function to reduce the environmental noise to be tested. interference. In addition, the conveyor belt is arranged to have a depressed depression and the wall is placed towards the test position of the product to be tested (for example, in a radial manner), which also helps to absorb and isolate environmental noise. Thereby, the audio test system of the present invention can automatically test the audio of the product to be tested and has a good test effect.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
