A radio with a wireless sound receiving function receives the radio and plays it externally, reaching a wireless sound transmitter that is amplified by the radio. [Prior technology] After examining the domestic patent No. 568327 "Digital Music Player" new patent, it also reveals a method for converting digital sound data into wireless sound signals to the radio for external broadcasting. However, this new patent case is only for digital audio data storage devices, and cannot receive analog sounds, numbers, that is, it cannot be directly connected to a commercially available sound player and played. Therefore, the scope of application of this new patent case is still limited. ^ Introduced on the market '1'-a kind of available-general sound playback media connection ^ FM sound converter 'Please refer to the ninth figure, it is a sound conversion device ⑺), which mainly consists of-cigarette lighter plug straight: (71) and FM sound converter (72), such as the tenth plug: The DC power supply (71) of the cigarette lighter plug is mainly connected to the cigarette lighter socket in the car using the cigarette lighter straight method (7, 1 1). (8 1), get L power. X 'The cigarette plug DC USB socket (7 1 9, l factory 1) 6 There is a sound 2 2)' For FM, state / 7 2) with plug (⑴), so the FM sound The converter (7 can be selected from the working power supply. The FM sound converter (7 2) is also provided with a 1239192 sound source insertion hole (7 2 2) for the earphone cable (8 3) to be plugged in.) :: The FM sound converter (7 2) can be connected with any = player that has a headphone jack. Because the FM sound converter (7 2) has a fixed FM frequency built-in, it can be converted to the FM frequency after the sound signal is input The audio signal is sent externally. In this way, the user can turn on the FM radio (8 2) and adjust to the same frequency in the car: he can receive the sound signal emitted by the FM sound converter (7 2), and then Played by the speakers inside the car. Delayed use of the FM audio converter can be used for personal sound players to use the car audio for amplification and broadcasting 'However,' this FM audio converter has the following disadvantages in use, such as failure to play smoothly Sound disturbed because Because the FM sound converter only has a set of FM frequencies built in, when the car is driving on a certain section and there is a radio station using the same FM frequency, the playback sound will be full of noise. The problem of FM; frequency: because the FM sound converter cannot display the FM frequency it is in. When the user wants to adjust the corresponding channel of the car radio to receive the sound signal emitted by the frequency sound converter, it will be impossible to know Tuning: frequency and it takes quite a long time to search for the same frequency; & w has the problem of power consumption, because the FM sound converter is directly powered by:: cigarette lighter 'and no power is set on _, So when Tianjiu started, 'If the user does not use the FM sound converter, it will continue to consume the power in the car; and it takes up space, because the FM sound converter is a two-piece design, so when When installed in the car, it will take up a lot of space for the gearbox ^ and occupy too much space in the car. Place 1239192 / In addition to the FM sound converter used in the car, The former driver also loves to use the mobile phone hands-free device, and the mobile phone hands-free device: Amplifies the incoming call signal of the mobile phone and converts it to the aforementioned FM sound; therefore, for users who want to install the two devices : Need to purchase separately, and the installation of hands-free handsets will occupy more space in the car.

Among them, the switch (δ 1) is connected to the sound conversion circuit 1239192 (52) of the circuit board (" 1), and the sound pickup circuit 1 15 6). Please refer to the ninth picture, 'The user is a sound player. (20) is plugged into the external dual media = connected to (6 0). Then control the switch (6 workers) to determine whether it is the monitor phone (4 2 U is the signal of the sound-cutting medium (2Q) is input to the sound conversion circuit (52) φ ^ ^ ^, ,, z J, and is converted into an FM signal for external transmission. Please refer to Figure 6 for cooperation. This is the third preferred embodiment of the present invention, most of which has the same structure as the first preferred embodiment, and the sound source connector (14) is also a headphone cable (14 1). However, the casing (1 1) is provided with an automatic rewinding device (1 8). The middle line of the headphone cable (! 4 1) is set on the automatic rewinding device (work 8). When not in use, the headphone cable (1 4 1) It will be rolled up in the casing (work), and only the earphone plug (142) is exposed on the casing. »Read more in the seventh figure, which is the fourth preferred embodiment of the present invention. Most of the structures are the same as the first preferred embodiment, except that the casing (1 i) is additionally provided with a power charging output 4 (19), and the power charging output port ( 19) It is connected to the output terminal of the voltage stabilization circuit (551) of the power supply circuit (5 $) on the circuit board (丄 丄), as shown in the third figure, to output the DC power after the voltage is stabilized. It is used by sound playback media (20) or Bluetooth mobile phones (42) that use the same DC power supply. Since most portable sound playback media (20) use dry batteries, there will be problems of battery replacement after long-term use. Therefore, the present invention provides a DC power supply: the charging output 珲 (19) 'can solve the problem that the sound playback medium (20) power cannot be provided in the car, and the playback is interrupted. 1239192 Shi Li According to the description of the above embodiments, the present invention is The FM sound of the circuit board is converted to a built-in complex FM stepper rate on the t-channel. It is equipped with a display and -press built-in, and 7 users can select a specific set of built-in FM _ frequency by the key set. The display can be selected when selected. The FM frequency value is clearly displayed. In this way, when the user matches the frequency of the radio in the vehicle σ δ week, 'the user can quickly adjust to the same FM frequency.' In addition to providing a more convenient way of use, the present invention also has the function of automatically and manually switching the hands-free function of a Bluetooth mobile phone, which has considerable convenience whether it is applied in a car or indoor. _ Is Therefore, the present invention does have industrial applicability, and meets the requirements of the novelty and progress of the invention, so it is filed in accordance with the law.
