Description of the Invention: The present invention relates to an output volume control device for a computer device sound device, and more particularly to a notebook computer having an automatic sensing environment volume and controlling an output volume. When the notebook returns from the silent mode to the normal broadcast mode, the ambient volume is detected first, and the output volume of the audio output device is controlled to a predetermined volume level according to the detected ambient volume level. [Prior Art] Most of the notebook computers currently available for commercial use have the function of multimedia playback. The built-in or external audio output device cooperates with the driver and application of the notebook computer to perform the function of video and audio playback. In order to enable the user to conveniently and quickly operate the function of audio and video playback, most of the commercially available keyboard devices of the notebook computer are provided with FN fast function keys, and the purpose thereof can be used to match various function keys F1~F12 to achieve various types. Quick keys for different functions. When the user wants to perform a preset quick key function, he only needs to press the FN function key and one of the preset function keys F1~F12 at the same time. For example, one of the basic function quick keys designed in current notebook computers or multimedia computers is the function of "Mute". Although the design of this quick function key allows the user to perform the mute function easily and quickly, it often causes great trouble. For example, when the user has to temporarily turn the sound of a large volume into a silent mode (such as publishing a venue) in some cases, and then needs to play some sound effects or restore the sound output mode, it is found that the previous computer has been set to be muted. Mode, then it will be again 1261881 Press the mute function button, (4) t out of the original great volume, make the moon and fertilizer, but at this time the computer device will be troubled by the atmosphere. The makers are responsible for the money and bad atmosphere. [Inventive content] Although most of the pen-printing components are available for the self-promotion of the volume - the use of the knobs - every county - cut off the silent Wei d4 volume 'but the adjustment knob Position, the square is 'first view the volume disturbance, in the operation there is no way H does not cause the sound of the expected volume of sleep, and now most of the: there is a user can be used to set the output of the second sound ' When using the user, the user still has to use the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ i ensure that you can't make it out of the way that you can't avoid the unpredictable volume of the user of the pen D-type computer, and the user can't handle the mute function. The user can only relieve the static and damage. The volume adjustment knob of the venue's air effect output device is used; carefully; the sound number is carefully.

The electronic circuit includes a sound receiving and releasing the slow-changing direct current, and the The amplified signal forms a latch, a driver in which the snoring car smashes. The impedance in the ring circuit is changed to == the above output signal to change the volume of the environment, and the ringing; is inconvenient for the volume of the sound. Here, the sub-second sub-tone, the detector is connected to the telephone, the second bell = A /, the cost of clothing, the cost of electronic components are higher, and the households - the electronic computer in the notebook computer is hard to install. ... The body line is also practically not feasible. Therefore, the main purpose of the present invention is to provide a notebook computer with an automatic sensing loop, which is based on the knowledge of the output of the notebook computer. = Quantitative: The device controls the sound of the notebook computer to drink and stand out. The purpose is to provide a control mode for the notebook computer to return from the silent mode to the normal broadcast mode. The rate of force 'protects the sound output device is not embedded. Another purpose is to provide a type of notebook computer, which is not controlled. The invention is in a state of extremely low conversion to the circuit architecture of the pen-type computer. The function of controlling the output volume of the sound output device is controlled. The purpose of reaching the appropriate U is to provide a method of “electricity=quantity and control of the output volume”, which can be 4=^曰, when the mode returns to the normal broadcasting mode, the sound effect output device is automatically adjusted according to the size of the environment day. The power of the output. The technical means for solving the problem of the present invention is based on the technical means used in the problem of the problem, and the production means includes a soil volume sensing and output volume control device sensing unit. Measure the notebook computer to use the second ΪΪΪΓ ° # The notebook computer detects a notebook computer pre-release signal, you can make the sound effect «set into the quiet, the style' and the notebook computer again _ to In the preferred embodiment of the present invention in which the mute is activated/released 1261178, the volume control device is connected to the notebook computer;:: output tone = controller with ambient volume The sensing unit can enter: quantity " calculate the output level, and control the sound effect_set: wheel: the invention compares the power of the prior art, through the technical means adopted by the invention, can return the formula to the normal broadcast mode At the time of the present invention, the sound volume output device automatically adjusts the sound effect output to protect the sound effect. _ is not subject to instant control, and the system combines the work of the embedded controller in the notebook computer =: at, low cost And the need to change the circuit structure of the notebook computer can achieve the purpose of controlling the output volume of the sound output device at the right time. [Embodiment] The first figure shows a block diagram of a notebook computer circuit function of the ambient volume sensing and output control U of the present invention.
