M253157 4. Creation Description (0 [Technical Field to which New Types belong] Especially the original creation used in mobile phones is about a mobile phone sound playback processing device. [Prior Technology] Mobile phones have become a necessary communication in human daily life Communication tools. Almost every modern person carries a mobile phone with them. Please refer to Figure 1A. Figure 1A is a schematic diagram of a conventional mobile phone 2a. General mobile phone 2a contains a long-range radio frequency communication module. 4. And a speaker 6. The long-range radio frequency communication module 4 is used for communication connection with a base station 8 and can enable the mobile phone 2a to transmit and receive sound radio signals between the base station 8. The speaker 6 is used to connect the base station 8. The received sound wave signal is broadcasted to the callee within a predetermined distance. Because the mobile phone 2 a is usually attached to the ear of the callee, the speaker 6 mostly uses an output power of 1 to 2 watts (W). The distance of the transmitted sound signal is also within 10 cm. In addition, some mobile phones with amplifying function 2 a will also include an output power of more than 4 watts. (W) The loudspeaker 10 above, so that the mobile phone 2 a broadcasts a sound signal to a callee more than 10 cm in the hands-free communication condition. The mobile phone 2 a can also be adjusted by The output power is such that sound signals of various powers are output from the same speaker, so the speaker can be both the loudspeaker 10 and the speaker 6 at the same time.

Page 5 M253157 4. Creation instructions (2) However, although the mobile phone 2a is almost a manpower, when salespersons in shops and street vendors call for sales, they use the long-range RF communication module 4 to transmit through the base station 8. The sound wave signal is sent to another mobile phone 2 b, otherwise the loudspeaker 10 of the mobile phone 2 b cannot be used to broadcast the sound signal to all the callees near the mobile phone 2 b. Furthermore, if things are announced during the meeting, the teacher lectures, find the lost mobile phone, etc., all of them must turn on the long-range radio frequency communication module 4 so that the loudspeaker 10 of the mobile phone 2b broadcasts the sound signal. The problem. Because it is necessary to transmit the sound wave signal between the mobile phone 2a and the base station 8 through the long-range radio frequency communication module 4, it will inevitably generate communication costs with the telecommunications company that owns the base station 8, which is quite uneconomical and must be applied The two mobile phones 2 a and 2 b require dialing to operate, which is quite inconvenient. In addition, please refer to FIG. 1B, which is a schematic diagram of the short-distance control mobile phone 2 of the conventional technology. The conventional technology uses a short-range wireless communication module 12 such as a Bluetooth, which is installed in a mobile phone 2 and a wireless headset microphone device 14 respectively. The user inputs sound through the radio microphone 15 of the wireless headset microphone device 14 The signal is transmitted to the mobile phone 2 through the short-range wireless communication module 12 as a sound radio wave signal, and then the sound radio wave signal is transmitted to the base station 8 through the long-range radio frequency communication module 4 to complete the distance control action. Phone 2 communication function. However, the mobile phone 2 is only a medium for signal transmission, and cannot be directly used in other mobile phones 2 such as the speaker 6 and the loudspeaker 10.

Page 6 M253157 4. Creation Instructions (3) Therefore, the main purpose of this creation is to provide a sound playback processing device used in mobile phones to solve the above problems.
