[0037] Embodiment 1:
[0038] like Figure 1 , Figure 2 , Figure 3 As shown, the control panel 100 includes a control panel body 110, a pin header 120 and an observation hole 130. The pin header 120 is arranged on the control panel body 110, and the pin header 120 is provided with a pin header hole 121, and the pin header hole 121 is used to abut against the pin header 140 inserted into the pin header hole 121; the observation hole 130 is provided on the control panel body 110 and / or the pin header 120, and the observation hole 130 is directly or indirectly connected with the pin header hole 121. Exemplarily, the observation hole 130 can be arranged on the control panel body 110, or on the pin header 120, or on both the control panel body 110 and the pin header 120. Specifically, in this embodiment, the observation hole 130 is arranged on the control panel body 110 and penetrates the control panel body 110, and on the orthographic projection of the control panel body 110, each observation hole 130 overlaps with or covers the corresponding pin header hole 121. In addition, it should be noted that when the observation hole 130 is set on the needle header 120, the observation hole 130 and the pin header hole 121 are directly connected. When the observation hole 130 is set on the control board body 110, because there is a gap between the needle header 120 and the control board body 110, the observation hole 130 and the pin header hole 121 are indirectly connected.
[0039] like Figure 1 , Figure 2 , Figure 3 As shown, the control board 100 provided by the technical solution of the present application has an observation hole 130 on the control board body 110 and / or the pin header 120, and the observation hole 130 is directly or indirectly connected to the pin header hole 121, so the inspector can visually observe the state of the pin 140 inserted into the pin header hole 121 through the observation hole 130, and timely check for abnormal plugging problems. When the pin 140 is plugged into the pin header 120, the pin pins of the pin 140 may be inserted incorrectly or bent. At this time, the inspector can observe whether the pin 140 in the pin header hole 121 is abnormal through the set observation hole 130, which is beneficial for the inspector to conduct quality inspection, and at the same time, it is beneficial to avoid the situation where the control board is short-circuited and burned after power is turned on. At the same time, it is beneficial to improve production efficiency, save costs, and reduce the number of defective products.
[0040] like Figure 1 , Figure 2 , Figure 3 As shown, in a possible implementation, the observation hole 130 is disposed on the control board body 110 and penetrates the control board body 110, and the observation hole 130 is directly opposite to the pin hole 121. Exemplarily, it can be understood that the area of the observation hole 130 should be greater than or equal to the area of the pin hole 121, so that the user can fully observe the plugging state of the pin hole 121 in the pin hole 121 through the observation hole 130.
[0041] like Figure 1 , Figure 2 , Figure 3 As shown, in a possible implementation manner, the number of observation holes 130 is the same as the number of pinholes 121, and each observation hole 130 is connected to one pinhole 121. Exemplarily, in this embodiment, each pinhole 121 is correspondingly provided with an observation hole 130, and it can be understood that the position of the observation hole 130 corresponds to the position of the pinhole 121.
[0042] like Figure 1 , Figure 2 , Figure 3 As shown, in a possible implementation, the shape of the observation hole 130 is one of a circular, rectangular, elliptical, and irregular shape. Exemplarily, in this embodiment, the shape of the observation hole 130 is rectangular, and correspondingly, the shape of the pin hole 121 is also set to be rectangular. Of course, in a specific application, the shape of the observation hole 130 is not limited thereto. For example, as an alternative, the observation hole 130 can also be set to be circular, elliptical, or other irregular shapes, which are not too limited here.
[0043] like Figure 1 , Figure 2 , Figure 3 As shown, in a possible implementation, the control board 100 further includes a pin header 140, and the pin header 140 is fixed to the control board 100 through the pin header hole 121. Exemplarily, the pin header 140 cooperates with the socket to realize electrical connection between control boards, or electrical connection between electronic components and control boards, or circuit connection between electronic components.
[0044] like Figure 4 As shown, to achieve the above purpose, the present application also proposes an intelligent audio device, including the above control board 100. Exemplarily, the intelligent audio device can be an electronic device such as a microphone, a speaker, a headset, an MP3, a mobile phone or a tablet.
[0045] Embodiment 2:
[0046] like Figure 5 As shown, compared with the first embodiment, the difference of this embodiment is that the setting position of the observation hole 130 is different, and the specific scheme is as follows:
[0047] like Figure 5 As shown, in a possible implementation, the observation hole 130 is arranged on the side 124 of the pin header 120, and the observation hole 130 is connected with the pin hole 121. Exemplarily, in this embodiment, the observation hole 130 is arranged perpendicular to the pin hole 121. It can be understood that at this time, the observation hole 130 and the pin hole 121 are in the shape of a "T" after rotating 90 degrees. Of course, in specific applications, the observation hole 130 can also be arranged to be inclined with respect to the pin hole 121. Based on the product shape, it is convenient for the inspector to observe the condition of the pin 140 in the pin hole 121. No excessive restrictions are made here. In addition, it should be noted that the side of the needle header 120 that contacts the control board body 110 is defined as the bottom surface 122, the side away from the bottom surface 122 is the top surface 123, and the side connected to the bottom surface 122 and the top surface 123 is the side surface 124. It can be understood that there are four side surfaces 124, and the observation hole 130 can be set on one or more of the side surfaces 124 to facilitate observation by inspectors based on the product shape.
[0048] like Figure 5 As shown, in a possible implementation, the observation hole 130 is disposed on a side of the side 124 of the pin header 120 close to the control board body 110. Exemplarily, the observation hole 130 is disposed on a side close to the control board body 110, that is, the position of the observation hole 130 should be conducive to observing the bottom of the pin header 140, because when the pin header 140 is matched with the pin header 120, the bottom of the pin header 140 is the most likely to be deformed or bent.
[0049] Except for the above-mentioned structural differences, the control board 100 and its components of this embodiment are the same as those of the above-mentioned embodiment 1, and will not be described in detail here.
[0050] Embodiment three:
[0051] like Figure 6 , Figure 7 As shown, compared with the first embodiment, the difference of this embodiment is that the size of the observation hole 130 is different, and the specific scheme is as follows:
[0052] like Figure 6 , Figure 7 As shown, in a possible implementation, the number of observation holes 130 is less than the number of pin holes 121, and one observation hole 130 is connected to one or more pin holes 121, so that each pin hole 121 is connected to the observation hole 130. Exemplarily, the difference from the first embodiment is that one observation hole 130 of the present embodiment can correspond to multiple pin holes 121, that is, the inspector can observe the conditions of the pins 140 in multiple pin holes 121 through one observation hole 130.
[0053] Except for the above-mentioned structural differences, the control board 100 and its components of this embodiment are the same as those of the above-mentioned embodiment 1 or embodiment 2, and will not be described in detail here.
[0054] Embodiment 4:
[0055] like Figure 8 As shown, compared with the first embodiment, the difference of this embodiment is that the object to which the needle header 120 is installed is different, and the specific scheme is as follows:
[0056] like Figure 8 As shown, in a possible implementation, the control board 100 further includes a chip 150, and the chip 150 is fixed on the control board 100 through the pin header hole 121. For example, both the first embodiment and the third embodiment are applied to the scenario where the pin header 140 cooperates with the pin header seat 120, and the observation hole 130 of this embodiment can also observe the pin status of the chip 150, and the observation hole 130 can be opened to observe the plug-in when the plug-in chip 150 is plugged into the pin header seat 120.
[0057] Except for the above-mentioned structural differences, the control board 100 and its components of this embodiment are the same as those of the above-mentioned embodiments 1 to 3, and will not be described in detail here.
[0058] like Figure 4 As shown, to achieve the above purpose, the present application also proposes an intelligent audio device, including the above control board 100. Exemplarily, the intelligent audio device can be an electronic device such as a microphone, a speaker, a headset, an MP3, a mobile phone or a tablet.
[0059] In addition, as to how to apply the control panel 100 described in the present application to smart audio devices, it should be set by technical personnel in this field when applied to specific smart audio devices, such as speakers, according to the volume of the speakers and the size of the control panel in the speakers. This part is not the focus of protection of this application, so this application will not elaborate on it.
[0060] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
