[First-hand technology] ❹ Lu u you! ^ The rapid development of multimedia technology with the sound of the shirt, the technology of the audio-visual player will be improved and grow (for example: TV, audio equipment, multi-media, even $1) Brain multimedia center, etc.), and can be designed to support f = kind of w sound format and additional functions. Furthermore, let; Xiao Fei public can have a better visual and auditory sense of enjoyment. When people use audio and video players, they tend to increase the volume of the sound in order to enjoy the shock of the I 2, which often hinders the problem in order to improve this. Therefore, users use it. The "hearing effect" - this way can avoid obstructing the peace of others, but because of the wired connection, the user must be limited by the distance of the earphone cable, and the activity will be inconvenient. With the growth of wireless transmission technology, the more wireless transmission technology is produced, the more users can make progress at this time, for example, using Bluetooth wireless headsets with Bluetooth transceivers to solve the above problems. However, in practical applications, the user must first connect the Bluetooth transceiver to the AV player before pairing with the Bluetooth wireless headset. This is only a problem for the entire assembly application and collection. Am In addition, since the wireless earphone and the audio and video player's audio source are independent, the user still wants to listen to the wireless headphones. Listen to the effect. Therefore, under these inconvenient factors, the user's additional purchase of wireless headphones and wireless transceivers is greatly reduced. Heart, [invention content] In view of this, the test of the hairpin in this day is based on design.

Therefore, the switching unit 211 performs the cutting and outputting according to the potential signal to output the sound source signal from the wireless earphone S through the control unit. Or by the module source interface 218 and the Yang 9 source signal. The signal connection interface 213 is connected between the earphone accommodating slot 2 丨 9 and the audio switching unit 211 for supplying the potential signal transmitted by the earphone accommodating groove 219 to the audio switching unit 211. And the potential signal transmitted therein is continuously referred to as a potential signal formed according to whether the wireless earphone 8 is placed in the earphone accommodating groove 219. The definition of the potential signal has been exemplified in the first embodiment, and will not be described herein. In this way, the external design method described in this embodiment can also achieve the purpose of switching the output path of 12 200934155. In addition, because the wireless audio transmission mode is designed, that is, the design has an external design, the power supply...connec (four) provided by the power supply, used to supply power 2 in the operation of the second power = interface 5 η as a spicy sound The transfer module has a charge transfer group 21211 further configured to receive the power supply interface 214 ',; | 14 when the mains connection is connected, 217 is charged. The power supply is connected to the module battery unit 213. Next, the power interface 214 is a push-to-talk, for transmitting the signal to the wireless headset 8 and the valley center 219 by transmitting the signal connection interface 213 and =1 to the signal connection interface. ❹ With a charging circuit (not shown), when the slot 219 can be entered, the headset battery (not shown) placed in the headset can be directly received for charging. ", and the 'child wireless headset 8 one, with the mention of 'the audio and video player body 20 can be, #立立;: f slot (not shown), let the wireless audio transmission module 21 plug : In the accommodating slot, the actual switching operation principle of the present invention is explained in order to increase the appearance and reduce the external space. The main diagram of the present invention is the second example of the audio switching unit used in the present invention. Circuit diagram. As shown in the figure, 13 200934155, the connector CONI is used to receive and transmit the sound source signal (belonging to the signal source) output by the sound source processing module. The connector c〇N2 is used to receive the potential signal transmitted by the signal connection interface. The connector c〇N3 is one of the output paths of the sound source signal for connecting to the control unit, and the connector CON4 is another output path for the sound source signal for connecting the speaker through the sound source interface. Thus, the control s, m, U2 is the potential signal transmitted by the connector (7) to perform different output paths of the city. ❹ When the user uses the wireless headset, the wireless headset will be disconnected from the ear slot. Then the potential signal received by the connector (3) N2 belongs to the = potential signal. In the circuit design, it is designed to have a resistor illusion to further ensure that the controller U1, U2 is the received low power (4) ^ so the controller m 'U2 will receive the j signal from the connector c (10) Switch to the connector (7) N3 and transfer to the control unit, and the user can hear the audio signal from the wireless headset. When the headset does not use the wireless headset, the wireless headset is placed in the lift, so the connector (10) 2 will receive the wireless headset "potential call. Therefore, the controller m, U2 will receive the audio signal from = CQN1 Switching to the connector c (10), in line two = and then the speaker connected to the sound source interface, the skilled person should be able to understand that the above circuit diagram can also be used for convenience, for the convenience of explanation, In the actual application design, the circuit is directly wired or otherwise connected, and is not transmitted to the Α 参考 Α Α 第四 第四 第四 第四 第四 第四 第四 第四 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 In this embodiment, the audio and video 14 200934155 player 1 is exemplified by Wei, and the wireless sound is implemented by a built-in design. "Transfer mode level 11 as shown in the fourth A picture, when the user wants When the wireless earphone 8 is detached from the earphone accommodating groove 14, the sound source signal is played, and the sound source signal that is played is 3, the shirt β player 1 is connected to the audio and video player i, and the earphone 8 is rotated. And if For example, using 9 will stop outputting sound. In addition, the characteristics of the operation, if the incoming materials are based on the Bluetooth technology = = = = can switch the Bluetooth connection, 3 yuan, you can switch to use the audio signal. I—^ to continue listening to the device. When the user puts the wireless headset 8 back to the ear, the switch is switched: the two games are played, and the job will not operate. In this case, the wireless headset 8 is transmitted: i:: The simplified circuit design, in order to have the wireless core secret 'integration of the ethnicity', so that the video player can be wheeled. And Γ, let the: and wireless headsets for wireless audio transmission, and the direct automatic incoming headset connection use does not need to change the Hais I I, the function of the transmission, but also let No, the habit of using, directly by the wireless headset storage, but the switching of the output path of the β σ video player. And the second embodiment: the detailed description of the specific embodiment with == to limit the present invention, All of the scope of the present invention is intended to cover the scope of the invention as defined in the following paragraphs. • [Simple Description of the Drawings] - The first figure is a block diagram of a first embodiment of the video player having the wireless audio transmission function of the present invention; the second figure is the second embodiment of the video player having the wireless audio transmission function of the present invention. Example block diagram; ❹ The third figure is a circuit diagram of an embodiment of an audio switching unit used in the present invention; and the fourth A picture and the fourth B picture are audio and video playback of the present invention with wireless audio transmission function Schematic diagram of the application.
