Playback device. ^ 大 k 成 饬 吾 ’s sound [Previous technology] Currently on the market, there are generally sound broadcast recorders, TVs, video recorders, walkmans, = two devices, regardless of the receiver, etc. 'At least two types of audio sources will be provided ^ or LCD shouts No ίο 15 or external speaker mode 1 type 'One is built-in, and the other is external earphone (MEar-phone) mode, allowing users to easily choose. When no headphones are plugged in, the sound is played by inserting the built-in speaker or speakers = volume control chess set ^ ° and for the installation of the output audio signal t 'own headphones are placed on the headphone plug, Set to play the audio signal from the source to the headset. The day-to-day automatic switch is output by the headphone jack as shown in the figure! 'Is a volume control mode of an existing sound playback device ^ has a volume control unit 11, an electrical volume control unit amplifier 12' and an electrical connection with the amplifier U The attenuation circuit is just like this), the earphone 13 is electrically connected to the attenuation circuit 14 and the amplifier 12, and a speaker 10 installed in the player device of the Pan9 ear 9 is also electrically connected to the amplifier 12. Volume control module! At the time of electrical conduction ', the sound source signal ⑼ is transmitted to the amplifier 12 through the volume control unit to amplify the signal and passed to the speaker w for playback. 20 5 10 15 20 M258500 When the earphone η and the volume control module are electrically connected, the sound source signal f tiger 101 is transmitted to the amplifier 12 to amplify it by the volume control, and the attenuation circuit 14 is attenuated and then amplified by the earphone 13 The next source signal is out = If the role of Road 14 is when the user uses the speaker 10 to listen ^ When Zhou Zheng's corpse ear volume is too loud, it is too late to switch to the earphone listening mode = to make the human ear and headphones Causes damage, so it is necessary to set this attenuation circuit M to appropriately reduce the volume of the source signal. However, the disadvantage of the attenuation circuit is that 'if the design is poor, the headphone output will be too low, and the sound effect will be satisfactory. In addition, the attenuation circuit 14 will easily cause the output to be too large and cause damage to the earphone and the human ear. Content] Therefore, Li Dan's "The Head of the New Model @" is providing a sound playback device that can regulate the appropriate output and reduce the damage caused by the ear-hearing mode. Therefore, the new type of sound playback with a volume control module The device has a casing for remote sound playing, and the casing is formed with a jack for plugging several pins. The sound playing device is used to process electrical signals from a source and provide an output. The signal is sent to a speaker or through the jack to 1 earphone. The volume control module includes —amplifier circuit, —: switching unit in the hole ’and —electrically connected to the switch“ the second put π to receive and amplify from The electrical signal of the audio source, the sub-supplier outputs the output signal to the speaker at the -th-magnification ratio ... Plug two = the output unit is connected to the headphone jack for power supply: / / early cut off the amplifier The output circuit of the speaker, and to the discharge M258500 two = - smaller than the first - second magnification of the magnification of the output signal to the output means to round out the earphone plug. ^ The amplifying circuit of the volume control module of the new sound playback device has an amplifier and a control circuit electrically connected to the amplifier to receive and amplify the electrical signal from the audio source. The: system amplifier Γ is actuated early and outputs a magnification control signal to the ίο 15 The sound exchange unit of the new sound playback device has a resistor and is electrically connected to the resistor == :::: A pair of electrical connections to the amplifying circuit and the second " voltage source and the = Γ: ί: Γ, the resistor 11 is connected to the ground terminal and the ground contact is made to contact the device with a single reading. When the pure level is applied to the second connection :::: when the machine plug lock is inserted, the guide piece is held in place by the headphone plug lock. Electricity: The shrapnel makes the switching unit turn the high and low level power from the power source: : Device ': This is the output of the device that turns out when the headphone plug lock is not inserted. This allows the controller to say goodbye to the speaker. The foregoing and other technical content, features, and effects will be clear in the detailed description of the preferred embodiment of the formula 4 «: This is another preferred embodiment of the new type of sound playback with a volume control module. The sound playback device 2 has a casing (Figure 20, M258500 1 and the machine), and a headphone plug is formed on the device (not shown). ） Connected jack 21 'Sound playback farm 2 is used to process electrical signals from-sound source 301, and to provide an output signal 3202 in the sound playback device 2 to a speaker 22 installed in it' Or for another-multiplying output signal 303 via jack 21: machine plug. In this preferred embodiment, the sound playback device 2 Γ in this example has a speaker sound mode and a headphone listening mode. For 'of course, it can also be a sound machine, television, video player, walkman, notebook computer, etc. with the above two listening modes. 15 20: The volume control module includes-amplifying circuit 23, _ switching unit M and- ^ 25 'amplifier circuit 23 is used to receive and amplify the hot ^ tiger from sound source 301' and output the output signal 3002 at a first magnification to the Yanglun output unit. 25 is electrically connected to the switching unit 24, Among them, = 25 series power supply The earphone pin, when the earphone pin is inserted, ^ change early 24 to control the amplifier circuit 23 and cut off the input of the speaker 22, and the amplifier circuit 23 transmits the signal 303 at a second magnification which is smaller than the first magnification. To output unit 25.

When the earphone is plugged into the output unit 25 _, the controller 232 uses the switching unit 24 as described below to change the voltage signal at different levels to cut off the original sound source 301 for amplification : 231 pair of the first magnification output signal 3002 of the speaker 22, and send the source signal 301 to the output unit 25 at an output signal M258500 303 that is smaller than the second magnification of the first magnification. This preferred implementation In the example, the switching unit ^ 24 has a resistor 241 and a lead piece 242 connected to the resistor 241, and the output unit M is a one-to-one spring piece 25 1, 252 connected to the amplifier circuit and not connected to each other. It has a thousand pieces without 252 and has a grounding end 253. The resistor 241 is connected to: =!

When a headphone pin is inserted, the earphone pin is held by its elastic force due to the elastic piece 252 to maintain a good power. "Sexual contact" Therefore, the elastic piece 25 and 252 are in the same state when the headphone pin is inserted, so the female and ▲ ^ m stand pieces 252 are also not touched by the guide piece 242, and the ^ piece 242 is no longer grounded. The electric voltage Vcc of the switching unit 24 outputs a South-level (High) voltage to the controller 232, so it can be separated from the low-level voltage not shown by the headphone pin, thereby enabling the controller 23 to respond to the "22 or to The headphone plug is given a rotation of different magnifications. It must be noted that the value of the second magnification preset in the controller 232 in the preferred embodiment is to attenuate its power to a percentage of the first magnification.
