Abstract

A display card includes a circuit board, a graphic processing unit and a noise reduction module. The circuit board has multiple gold fingers. The graphic processing unit is disposed on the circuit board. The noise reduction module is disposed on and electrically connected to the circuit board. The noise reduction module includes an active noise cancellation and a speaker electrically connected to the active noise cancellation. The speaker is capable of emitting a noise reduction sound to offset a noise from surrounding environment by the noise reduction sound. Thereby, the disclosure can effectively overcome the disturbing problem of noise.

First claim

What is claimed is:

1. A display card with a noise reduction mechanism, comprising:
a circuit board, comprising multiple gold fingers;
a graphic processing unit, disposed on the circuit board; and
a noise reduction module, disposed on and electrically connected to the circuit board, comprising an active noise cancellation and a speaker electrically connected to the active noise cancellation, the speaker being capable of emitting a noise reduction sound to offset a noise from surrounding environment by the noise reduction sound.

2. The display card of claim 1 , wherein the active noise cancellation and the speaker are fixed on and electrically connected to the circuit board.

3. The display card of claim 2 , wherein the noise reduction module further comprises a microphone, and the microphone is fixed on the circuit board and electrically connected to the active noise cancellation.

4. The display card of claim 3 , wherein the microphone comprises a reference microphone and an error microphone.

5. The display card of claim 1 , wherein the noise reduction module further comprises a microphone, and the microphone is fixed on the circuit board and electrically connected to the active noise cancellation.

6. The display card of claim 5 , wherein the microphone comprises a reference microphone and an error microphone.

7. The display card of claim 1 , wherein the noise reduction module further comprises a secondary circuit board, the secondary circuit board is fixed on and electrically connected to the circuit board, and the active noise cancellation and the speaker are fixed on and electrically connected to the secondary circuit board.

8. The display card of claim 7 , wherein the noise reduction module further comprises a microphone, and the microphone is fixed on the secondary circuit board and electrically connected to the active noise cancellation.

9. The display card of claim 8 , wherein the microphone comprises a reference microphone and an error microphone.

10. The display card of claim 1 , wherein the noise reduction module further comprises a secondary circuit board, the active noise cancellation and the speaker are fixed on and electrically connected to the secondary circuit board, the secondary circuit board comprises multiple insert terminals, and the secondary circuit board is electrically connected with the circuit board by each insert terminal.

11. The display card of claim 1 , wherein the noise reduction module further comprises a secondary circuit board, the active noise cancellation and the speaker are fixed on and electrically connected to the secondary circuit board, the secondary circuit board comprises multiple press terminals, and the secondary circuit board is electrically connected with the circuit board by each press terminal.
