Description

The present invention is a heat dissipation type USB audio digital AMP built-in speaker laid down as a notebook computer stand [Problem to be Solved by the Invention]

Computer software related to video and music has become widespread, and music and DVD video are often viewed on a laptop computer. When used only on the computer itself, the volume can be heard only on a monitor and the sound quality is excellent. I can't say that.

In order to improve volume and sound quality, connect external speakers to a notebook computer, install them on the left and right, and connect cables. In addition, connect either the output terminal or earphone terminal of the notebook computer to the amplifier of the speaker. Many power supplies are separate from the PC. It is very complicated.

As mentioned above, when listening to music or watching movies on a conventional laptop computer, neither sound quality nor volume is satisfactory.
However, if you connect external speakers and listen in stereo, you may need to connect at least 2 units or 3 units with a woofer. Ease of use, such as taking the place and being easy to use, is lost. [Means for solving problems]

The present invention is originally intended for use with a notebook computer, has a small space design, and can be easily carried.
Based on the above, speakers that can be connected with a single USB cable and have the effect of diffusing the heat generated from the bottom of the notebook computer, taking into account volume, sound quality, etc. It is a realization of the stand.

First, the present invention is a small space design in which a speaker system is constructed in an inclined table as shown in FIG. 1 and a notebook type personal computer is placed on the table so that no space other than the outer shape of the notebook is required.
"About the outer case"

  By tilting the base, the conventional PC can be operated easily, and the heat generation efficiency of the notebook PC is increased by using an aluminum plate with good heat conduction efficiency on the contact surface.

  In order to lose the escape route of sound etc. by placing a notebook on the table, a mesh aluminum plate is used on the lower side of the table as shown in FIG.

  A panel that vibrates like 001 in FIG. 1 is turned downward, and a panel stopper 401 is attached along a corner of the lower surface of the panel as shown in FIG. Separate the sound from the sound from above and reduce interference.

  The exciters that vibrate the panel are shifted so that they do not interfere with each other as shown in FIG. 2, and the exciter is embedded in the bobbin and bonded as shown in FIG. 4, and the vibrating surface is cloth adhesive tape as shown in 301 of FIG. Adhere with. The height of the stand can be lowered by embedding the exciter in the panel.

As shown in 002a and 002b in Fig. 4, the cable for connecting to the amplifier is rotated once and the exciter and the cable are bonded together, so there is no need to attach the exciter. Use it to increase the volume.
"Digital amplifier"

Reference numeral 101 in FIG. 1 denotes a USB audio digital amplifier that was originally developed.
It operates with a small amount of power by making it digital, and heat generation is very small compared to analog amplifiers.
Also, a clear sound with little noise can be obtained.

  2 in FIG. 2 is an external input (input) terminal, and external input is given priority.

  The portion 102 (USB audio board) in FIG. 5 is a board for transmitting left and right sound and power to a digital amplifier via a USB cable from a personal computer.

  Reference numeral 103 in FIG. 5 denotes a digital power amplifier that operates with the power source received from 102 in the digital amplifier portion, amplifies the left and right sounds received from 102, and vibrates the exciter.

  The output side of the digital amplifier is full power output, and the volume on the input side is adjusted with the volume of 104. The two-button volume specific to the digital amplifier is very difficult to use, and the rotary stereo on the input side A volume is attached.

  The reason why the input volume is added is that there is a limit to the power consumption of USB other than the one described in [0013]. When power supply such as an amplifier is supplied from USB, if the power consumption limit is exceeded, the personal computer will cause an error. If there is a risk that the sound of a DVD movie suddenly increases, the power consumption may exceed the specified level, so adjustments can be made to suit each output.

  In this USB audio digital amplifier, the USB audio and digital amplifier can be used independently by folding the line A in FIG. 5 by hand.

  By separating the board, each USB board and digital amplifier can be used alone, and moving the digital amplifier position frees space.

  In addition, the power consumption problem described in [0016] can also be separately supplied to each other so that the USB input side can use the power supply of the notebook personal computer side and the amplifier can use the external power supply. Because of this, the maximum capabilities of a digital amplifier can be demonstrated.

  As described above, the installation of the panel board exciter, the original USB audio digital amplifier, and the use of an aluminum plate for the contact surface makes it possible to create a notebook computer stand with speakers that is optimal for notebook computers. Moreover, it can be changed according to the purpose, for example, by attaching it to the base or arm stand of a notebook personal computer simply by changing the outer case for [FIG. 7] and [FIG. 8].

Claims (3)

It can be used as a base for notebook computers, and it can capture power and audio signals with just a USB (Universal Serial Bus) connection to produce realistic sounds.
If a personal computer stand is used, it can be used as a speaker with higher sound quality, and using a digital AMP consumes less power and generates less heat.
A heat dissipation effect can also be obtained by using an aluminum plate for the contact surface with the notebook computer. The digital AMP equipped with the USB audio digital amplifier USB has an integrated structure, but the two circuits can be separated, and it can be separated by hand along the groove of the board. The digital AMP board portion is cut off, and the power supply and signal system terminals are independent and can be used according to the application. The exciter is embedded in the diaphragm up to the bobbin part and bonded, and the signal cable is rotated and bonded to the exciter head once, so that exciter fixing brackets are not required and the exciter's vibration can be extracted to the maximum.
