[0029] Embodiment 1
[0030] Reference Figure 1-4As shown, a circuit board assembly is disclosed, which includes a flexible circuit board 1, a sensing control device 2 and at least one sound receiving unit 3. The sensing control device 2 is used to receive or send sensing control signals, and the sound receiving unit 3 is used to receive sound signals. The flexible circuit board 1 is folded to form a first board portion 11, a second board portion 12 and a connecting portion 13 connecting the two. The first board portion 11 and the second board portion 12 are spaced apart and substantially parallel. It should be noted that the substantially parallel arrangement here should be understood as that the first board portion 11 and the second board portion 12 are not strictly parallel, but a certain parallel error is allowed between the two, that is, the inclination angle between the two can be between 0-20°. The sensing control device 2 is arranged on a side of the first board portion 11 away from the second board portion 12, and each sound receiving unit 3 is arranged on a side of the second board portion 12 away from the first board portion 11. The second board portion 12 is provided with a sound receiving hole 121 at each sound receiving unit 3, and the sensing control device 2 and each sound receiving unit 3 are staggered. The sensing control device 2 includes an infrared unit and / or a temperature sensor and / or a humidity sensor. When the sensing control device 2 is an infrared unit, the sensing control device 2 is used to receive or send a sensing control signal, which should be understood as the sensing control device is used to receive or send an infrared signal. The sensing control device can also be a distance sensing device, which can be an infrared sensor, or a laser sensor, a millimeter wave radar sensor, a human proximity sensing module, etc., which is used to sense the distance of the user to start the device or start the device screen and other modules. The sensing control device can also be a prompt light, such as a prompt light that can send a prompt message after the user operates the device.
[0031] In the above-mentioned setting, the sensor control device 2 is arranged on the first board portion 11, and the sound receiving unit 3 is arranged on the second board portion 12, and the first board portion 11 and the second board portion 12 are arranged substantially in parallel, so the sensor control device 2 and the sound receiving unit 3 can simultaneously receive the sensor control signal and the sound signal from the normal direction of the first board portion 11, thereby improving the adaptability. Moreover, since the sensor control device 2 and each sound receiving unit 3 are staggered with each other, the shielding of the sound receiving unit 3 by the sensor control device 2 is avoided, thereby ensuring the sound receiving effect of the sound receiving unit 3. In addition, the sensor control device 2 and the sound receiving unit 3 share a flexible circuit board 1, thereby saving manufacturing costs.
[0032] In this embodiment, the number of the sound receiving units 3 is two, and the two sound receiving units 3 are evenly arranged along the circumference of the sensor control device 2. Such a configuration can balance the material cost and the sound receiving effect. In other words, using three or more sound receiving units 3 has limited improvement on the sound receiving effect, but increases the material cost.
[0033] In this embodiment, the circuit board assembly also includes a sealing plate 4, which is arranged in the gap between the first plate portion 11 and the second plate portion 12, and the first plate portion 11 and the second plate portion 12 are respectively connected to the sealing plate 4, and the sealing plate 4 is also provided with first through holes 41 which are equal in number to and correspond to the sound receiving holes 121. By providing the sealing plate 4, the structural strength of the flexible circuit board 1 can be improved, that is, the sealing plate 4 is equivalent to providing a rigid support skeleton for the flexible circuit board 1. The sealing plate can be specifically a foam backing adhesive, so that the structure of the first plate portion and the second plate portion is more stable, and the connection between the flexible circuit board and the middle frame is more stable. The first through holes 41 are provided on the sealing plate 4 to avoid the sealing plate 4 blocking the sound receiving holes 121, thereby ensuring the sound receiving effect.
[0034] In this embodiment, the diameter of the first through hole 41 is not less than the diameter of the sound receiving hole 121. In this way, the influence of the sealing plate 4 on the sound receiving effect can be minimized, and even to a certain extent, the first through hole 41 can bring sound receiving gain. Specifically, the first through hole 41 and the sound receiving hole 121 can be regarded as microphone holes, and the larger end of the microphone hole is the end where the first through hole 41 is located, so that the effect of sound receiving gain can be brought.
[0035] In this embodiment, the first plate portion 11 and the second plate portion 12 are respectively bonded to the sealing plate 4. The bonding method is simple in process and easy to operate, and can enhance the airtightness of the device, ensuring that the sound receiving unit 3 in the device can receive sound better.
[0036] In this embodiment, coaxially arranged positioning holes 61 are provided on the first plate portion 11, the second plate portion 12 and the sealing plate 4. The coaxially arranged positioning holes 61 can facilitate assembly. Specifically, when assembled with other components, the pin shaft can be inserted into the coaxial multiple positioning holes 61 to complete the assembly, which is very convenient.
[0037] In this embodiment, refer to Figure 7-8 The second plate portion 12 is provided with a first notch 122 and a second notch 123 formed by the circumference thereof being recessed toward the middle, the connecting portion 13 is connected to the first notch 122 of the second plate portion 12, and the second notch 123 of the second plate portion 12 is suitable for connecting the flat cable 8. With such a configuration, when the connecting portion 13 is connected to the first notch 122 and the flat cable 8 is connected to the second notch 123, the connecting portion 13 or the flat cable 8 can be prevented from protruding from the second plate portion 12, thereby playing a role in saving space.
[0038] Embodiment 2
[0039] The difference between the second embodiment and the first embodiment is that the circuit board assembly does not include the sealing plate 4, so in this embodiment, only coaxial positioning holes 61 are provided on the first plate portion 11 and the second plate portion 12. Similarly, the coaxial positioning holes 61 can facilitate assembly.
[0040] Embodiment 3
[0041] Reference Figure 2 , Figure 5-6 , Embodiment 3 discloses an intelligent control switch, which includes a bracket and the circuit board assembly in Embodiment 1, wherein the second plate portion 12 is disposed with one side away from the first plate portion 11 facing the bracket 5, and a positioning pin 51 is disposed on the bracket 5, and the positioning pin 51 is suitable for cooperating with the first plate portion 11, the second plate portion 12 and the positioning hole 61 on the sealing plate 4. By cooperating with a plurality of positioning holes 61 through one positioning pin 51, assembly can be facilitated, making the structure more compact.
[0042] In this embodiment, continue to refer to Figure 2 The bracket 5 is provided with a receiving groove 52 on one side facing the second plate portion 12, which is equal to the number of the sound receiving units 3. Each receiving groove 52 is suitable for receiving each sound receiving unit 3 in a one-to-one correspondence. In this way, the thickness of the circuit board assembly in the direction from the second plate portion 12 to the first plate portion 11 can be reduced, making the entire circuit board assembly thinner and occupying less space. In addition, the receiving groove 52 can also protect the sound receiving unit 3.
[0043] In this embodiment, the intelligent control switch also includes a middle frame 7, a circuit board assembly is arranged on the middle frame 7, a second through hole 71 is provided on the middle frame 7, the sensing control device 2 of the circuit board assembly is located in the second through hole 71, and the middle frame 7 is also provided with sound receiving through holes 72 which are equal in number and correspond one to one to the sound receiving holes 121. The sensing control device 2 is located in the second through hole 71 of the middle frame 7, which saves space and has good effects in transmitting and receiving infrared. If it is a temperature and humidity sensor, it can better sense the temperature and humidity around the device. The sound receiving through holes 72 provided on the middle frame 7 prevent the middle frame 7 from blocking the sound receiving holes 121, thereby ensuring the sound receiving effect.
[0044] In this embodiment, the diameter of the sound receiving through hole 72 is not less than the diameter of the sound receiving hole 121. Similarly, such a configuration can minimize the influence of the middle frame 7 on the sound receiving effect, and even to a certain extent, the sound receiving through hole 72 can bring sound receiving gain.
[0045] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
