Detailed Description

The utility model will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to fig. 3, the sound detection apparatus for a television set according to the present embodiment includes a plurality of acousto-optic conversion modules and an image collector; as in the present embodiment, five televisions 100 in the same group are synchronously detected, so that the number of the acousto-optic conversion modules is five, and the five acousto-optic conversion modules are respectively disposed on the five televisions 100. The acousto-optic conversion module comprises a vibration sensor 10, a first processor 20, a light emitting source 30 and a power supply, wherein the first processor 20 is respectively electrically connected with the vibration sensor 10 and the light emitting source 30 and is powered by the power supply, the vibration sensor 10 corresponds to a bell mouth 110 of a television 100 to sense vibration when the television 100 emits sound, the output end of the vibration sensor 10 is connected with the input end of the first processor 20, and the output end of the first processor 20 is connected with the light emitting source 30 to control the light emitting source 30 to emit light; specifically, when the vibration sensor 10 detects the vibration of the speaker of the television 100 (i.e. the television 100 is in the sound-emitting state), the information is transmitted to the first processor 20; after the first processor 20 obtains the signal, the light emitting source 30 is controlled to emit light; in this way, the sound of the television 100 is converted into a light signal to be visually indicated.

The image collector 40 simultaneously corresponds to the light sources 30 of the plurality of acousto-optic conversion modules to collect the light information of the light sources 30 of the plurality of acousto-optic conversion modules. The detection personnel can visually confirm whether the plurality of televisions 100 are in normal sounding at the same time; if the light sources 30 corresponding to the first to fourth tv sets 100 are illuminated and the light sources 30 corresponding to the fifth tv set 100 are not illuminated in five tv sets with the same channel and the same volume, the sound emitting of the first to fourth tv sets 100 can be intuitively determined to be normal and the sound emitting of the fifth tv set 100 is abnormal. The implementation mode is simple, the detection efficiency is high, and the accuracy is high.

The image collector 40 is adopted to simultaneously collect the luminous sources 30 of the plurality of acousto-optic conversion modules, so that the detection personnel can visually confirm through one picture at any time interval. Specifically, for more convenience, in this embodiment, the image information collected by the image collector 40 is directly uploaded to a remote terminal, so that the detection personnel can perform remote centralized confirmation. Specifically, one of the preferable structures for realizing the method is as follows: the image acquisition device further comprises a second processor 50 and a communication unit 60, wherein the output end of the image acquisition device 40 is connected with the output end of the second processor 50 so as to transmit the acquired image information to the second processor 50, and the second processor 50 is in communication connection with a remote end through the communication unit 60 so as to transmit the image information to the remote end. More specifically, the communication unit 60 is preferably a wireless communication unit, such as WiFi, bluetooth, etc. in the prior art. Of course, a wired communication unit may be used.

The image information collected by the image collector 40 is uniformly uploaded to the remote end in a remote transmission mode, so that detection personnel can confirm the conditions detected by the multiple groups of detection mechanisms at the remote end, and the efficiency is higher. Of course, in other embodiments, the image information collected by the image collector 40 may not be transmitted remotely, for example, the image collector 40 with a memory card is adopted to store the collected image information first, and then the subsequent detection personnel call the stored image information to perform the judgment.

Further, in this embodiment, the image collector 40 is a camera, and the camera can perform shooting monitoring in the whole process, so that the collected information is more complete. Of course, in other embodiments, the camera may be used, and when the camera is used, shooting may be performed once at regular intervals, and thus, capturing may be performed well.

Further, in this embodiment, the acousto-optic conversion module further includes a housing 70, and the vibration sensor 10, the first processor 20 and the light emitting source 30 are all mounted on the housing 70. Therefore, the acousto-optic conversion module is integrated and is convenient to take and place.

Specifically, in this embodiment, the housing 70 is a long rod structure, the vibration sensor 10 and the light-emitting source 30 are respectively located at two end positions of the housing 70, so that when the test is performed again, the housing 70 is fixed on the television 100, the vibration sensor 10 corresponds to the bell mouth 110 of the television 100, the light-emitting source 30 is located at an outer end of the television 100, the light-emitting source 30 can be far away from the display screen of the television 100, so as to achieve good distinction, and light between the two is not easy to be confused. Of course, in other embodiments, the shock sensor 10, the first processor 20 and the light emitting source 30 may not be mounted on the housing 70, and the three may be connected by wires. Thus, the light emitting sources 30 can be placed according to actual requirements.

More specifically, the housing 70 is fixed to the television 100 by tape bonding, and by tape bonding, the structure of the television 100 or the housing 70 does not need to be changed, so that the housing is convenient to take and place, and the television 100 and the housing 70 are not easily damaged. Of course, in other embodiments, the manner in which the housing 70 is secured to the television 100 is not limited thereto.

Further, in the present embodiment, the light source 30 is an LED indicator, such as a red LED indicator, which is mature in operation, fast in response and long in service life. Of course, in other embodiments, light emitting source 30 is not limited to LED indicator lights, and other types of indicator lights may be used.

Further, in this embodiment, the image collector 40 also simultaneously corresponds to the display screens of multiple televisions 100 in the same group to collect display information of the display screens. Thus, the display screen function of the television 100 can be synchronously confirmed, and the detection effect is better.
