[0019] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.
[0020] A wearable display module with a microphone, referring to Figure 1 and Figure 2 , includes a display module 10. The display module 10 includes a cover plate 20 and a display screen 30 arranged in sequence. The size of the cover plate 20 is larger than the size of the display screen 30, and the four sides of the cover plate 20 all extend beyond the four side edges of the display screen 30.
[0021] Referring to Figure 2, a circuit board 40 is provided on one side of the display module 10. The circuit board 40 is located on the side of the display screen 30 away from the cover plate 20. A microphone 50 is encapsulated on the circuit board 40, and the microphone 50 is encapsulated on the back of the circuit board 40, that is, on the side of the circuit board 40 away from the cover plate 20. The microphone 50 is relatively arranged in the upper side area where the cover plate 20 extends beyond the display screen 30, and the microphone 50 is arranged above the display screen 30.
[0022] Referring to Figure 2 and Figure 3 , a sound receiving hole 21 is opened on the front surface of the display module 10 at a position relative to the microphone 50. The sound receiving hole 21 is opened on the cover plate 20, and the sound receiving hole 21 penetrates through both sides of the cover plate 20 so that the outside communicates with the microphone 50.
[0023] Further, referring to Figure 2 and Figure 3 , an opening 41 is opened on the circuit board 40 in the sound receiving area relative to the microphone 50. The opening 41 enables the sound receiving area of the microphone 50 to communicate with the outside. The sound receiving hole 21 on the cover plate 20 and the opening 41 on the circuit board 40 are arranged relatively, so that the sound receiving hole 21 on the cover plate 20 and the sound receiving area of the microphone 50 are arranged relatively, facilitating the sound from the outside to be directly transmitted to the sound receiving area of the microphone 50 through the sound receiving hole 21 and the opening 41 for sound collection, reducing the loss of sound transmission inside the circuit board 40, and thus improving the call quality.
[0024] Further, referring to Figure 2 and Figure 3 , the size of the sound receiving hole 21 on the cover plate 20 is larger than the size of the opening 41. The sound receiving hole 21 can enable more sound to be transmitted into the display module 10 and be collected by the microphone 50 from the opening 41 or other areas.
[0025] Further, referring to Figure 2 and Figure 3 , the microphone 50 is integrated on the back of the cover plate 20, that is, the circuit board 40 provided with the microphone 50 is pasted on the back of the cover plate 20. The circuit board 40 is a flexible circuit board and can be bent. The area of the circuit board 40 with the microphone 50 is bent and attached to the back of the cover plate 20. The bending part of the circuit board 40 is located above the display screen 30, and the display screen 30 is located below the microphone 50. The circuit board 40 with the microphone 50 is attached to the back of the cover plate 20 so that the microphone 50 is directly fixed on the back of the cover plate 20. The sound receiving hole 21 on the cover plate 20 is arranged corresponding to the opening 41 on the circuit board 40 and the sound receiving area of the microphone 50, and the sound will directly enter the microphone 50 through the sound receiving hole 21 to achieve the sound collection effect.
[0026] Referring to Figure 2 and Figure 3, a paste layer 60 for pasting and fixing is provided between the circuit board 40 and the cover plate 20. The two opposite sides of the paste layer 60 are respectively pasted to the cover plate 20 and the circuit board 40. The paste layer 60 has a certain thickness to buffer the cover plate 20 and the circuit board 40, so as to prevent the circuit board 40 from directly contacting the cover plate 20.
[0027] Further, referring to Figure 2 and Figure 3 , a relief hole 61 is provided at the position of the paste layer 60 relative to the sound receiving hole 21. The size of the relief hole 61 is adapted to the size of the sound receiving hole 21, so as to prevent the paste layer 60 from affecting the entry of external sound into the microphone 50.
[0028] Referring to Figure 2 and Figure 3 , the wearable display module 10 integrates the microphone 50 onto the display module 10. When speaking to the wearable device, the sound will directly enter the microphone 50 through the sound receiving hole 21 of the cover plate 20 for sound collection, reducing the loss of sound transmission inside the main board, thereby improving the sound quality.
[0029] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
