具体实施方式Detailed ways

为能更了解本发明的技术内容，特举一较佳具体实施例说明如下。In order to better understand the technical content of the present invention, a preferred specific embodiment is given as follows.

图1为本实施例的操作环境示意图，请一并参照图2为本实施例的功能方块图，本实施例的车用随身MP3播放装置，使用于车辆9上，如图1所示，于一般车辆9乘员室内的仪表板上均组设有一收音机，在本例中使用可解调RF射频的车载射频收音机92。于本实施例中，车用随身MP3播放装置包括有一外壳体10、以及一电源插头12，并于外壳体10内组设有一射频发射器13、一输入介面14、以及一MP3擂放器11。其中，电源插头12凸设于外壳体10前端，并可对应插入车载射频收音机92所组设的电源插孔91内，以获取电力。Fig. 1 is a schematic diagram of the operating environment of the present embodiment, please refer to Fig. 2 in conjunction with the functional block diagram of the present embodiment, the car portable MP3 player of the present embodiment is used on the vehicle 9, as shown in Fig. 1, in A radio is all grouped on the instrument panel in the passenger compartment of the general vehicle 9 , and in this example, a vehicle-mounted radio frequency radio 92 that can demodulate RF radio frequency is used. In the present embodiment, the car portable MP3 player includes anouter casing 10 and apower plug 12, and in theouter casing 10, a radio frequency transmitter 13, aninput interface 14, and anMP3 playback device 11 are assembled. . Wherein, thepower plug 12 protrudes from the front end of theouter casing 10, and can be correspondingly inserted into the power jack 91 formed by the car radio 92 to obtain power.

由电源插头12获得的电力，上述MP3播放器11可撷取一MP3资料档予以播放，再通过射频发射器13调变以射频载波无线广播出去，此经车载射频收音机92的无线接收及解调变后，便可通过车上Hi-Fi音响系统的喇叭予以播放。由于本实施例以体积小巧的行动MP3播放装置取代公知的CD匣播放盒，确实能降低车上存取CD空间及置换CD匣的不便利性，并可增加车辆内部空间使用上的弹性。With the power obtained from thepower plug 12, the above-mentionedMP3 player 11 can extract an MP3 data file to play, and then modulate and broadcast wirelessly with a radio frequency carrier through the radio frequency transmitter 13, which is wirelessly received and demodulated by the car radio 92 After changing, it can be played through the speakers of the Hi-Fi audio system on the car. Because this embodiment replaces the known CD box player box with a small and exquisite mobile MP3 player device, it can indeed reduce the inconvenience of accessing the CD space and replacing the CD box on the car, and can increase the flexibility in the use of the interior space of the vehicle.

本例将所播放的MP3音乐歌曲通过射频发射器13的射频载波无线传送至车载射频收音机92，以经由车上的音响系统予以播音时，首先必须将车载射频收音机92的接收频率调整至与车用随身MP3播放装置的发射频率相同的频率。在本例中车用随身MP3播放装置上设置有一射频波段频率选择器131，此射频波段频率选择器131于本实施例中可设定五组不同的发射频率，以做为切换车用随身MP3播放装置的发射频率，而车用随身MP3播放装置发射频率的选择是取决于当地电台间的空间频率区段，以免电台互相干扰而造成收音失真，例如：A电台的射频发射频率为98.3MHz，B电台的射频发射频率为98.9MHz，则较佳地是我们可撷取中间值的98.5MHz或98.7MHz来做为本例车用随身MP3播放装置的发射频率，以此方法可设定出五组不同频率，做为切换车用随身MP3播放装置的射频播放频率之用。纵使本例所选择的发射频率不幸与当地既有电台的频率重叠相同，但如图1所示，由于该车用随身MP3播放装置插置于车载射频收音机上的电源插孔91内，因此本例车用随身MP3播放装置的射频信号相对较强不会被盖台，驾驶人可安心收听本装置的MP3音乐。图示前述射频波段频牢选择器131于本实施例中为一指拨开关，并位设于外壳体10上，其亦可为一可调旋钮、或电子式固定频率选择器…等，或其他等效频率调整装置皆可。In this example, the played MP3 music song is wirelessly transmitted to the car radio 92 by the radio frequency carrier of the radio frequency transmitter 13, and when broadcasting through the sound system on the car, at first the receiving frequency of the car radio 92 must be adjusted to the car radio 92. Use the same frequency as the transmission frequency of the portable MP3 player. In this example, the car portable MP3 player is provided with a radio frequencyband frequency selector 131, and this radio frequencyband frequency selector 131 can set five groups of different transmission frequencies in this embodiment, so as to switch the car portable MP3 The transmission frequency of the playback device, and the selection of the transmission frequency of the portable MP3 player for the car depends on the spatial frequency segment between the local radio stations, so as to avoid radio interference caused by radio distortion. For example: the radio frequency of radio station A is 98.3MHz, The RF transmission frequency of radio station B is 98.9MHz, then preferably we can extract the median value of 98.5MHz or 98.7MHz as the transmission frequency of the car portable MP3 player in this example, and five can be set in this way Different frequencies are used for switching the radio frequency of the car portable MP3 player. Even though the selected transmission frequency of this example unfortunately overlaps identically with the frequency of the local existing radio station, as shown in Figure 1, because the portable MP3 player for this car is inserted in the power jack 91 on the car radio frequency radio, so this For example, the radio frequency signal of the portable MP3 player device for a car is relatively strong and will not be blocked, and the driver can listen to the MP3 music of the device with peace of mind. The above-mentioned radio frequencyband frequency selector 131 shown in the figure is a dip switch in this embodiment, and is located on theouter casing 10, and it can also be an adjustable knob, or an electronic fixed frequency selector...etc., or other Any equivalent frequency adjustment device is acceptable.

于本实施例中，上述MP3播放器11所播放的MP3资料档可预先储存于一内建式储存装置15中，由MP3播放器11直接读取其中的MP3资料档经解码后再播放。此外，本例的车用随身MP3播放装置亦设有一输入介面14其电连接至一USB连接器141，如图3所示，此USB连接器141可提供一外接式USB随身盘140由外部插接用，其中，前述外接式USB随身盘140内储存有欲播放的MP3资料裆；或者是，如图1所示，将该行动MP3播放装置拔出后携回家中，利用家中电脑将自己喜爱的MP3资料档通过USB连接器141转录至内建式储存装置15内，留待上车时播放使用。In this embodiment, the MP3 data files played by the above-mentionedMP3 player 11 can be pre-stored in a built-instorage device 15, and the MP3 data files therein can be read directly by theMP3 player 11 and then played after being decoded. In addition, the car portable MP3 player device of this example is also provided with aninput interface 14 which is electrically connected to aUSB connector 141, as shown in Figure 3, thisUSB connector 141 can provide an externalUSB flash drive 140 to be plugged in from the outside. Connect and use, wherein, store the MP3 data crotch that wants to play in the aforementioned externalUSB flash drive 140; Or, as shown in Figure 1, after pulling out this mobile MP3 player, take it home, utilize the computer at home to Favorite MP3 data files are transcribed into the built-instorage device 15 through theUSB connector 141, and then played when getting on the car.

此外，车用随身MP3播放装置的外壳体10外周可增设有三个操作键111，用来控制MP3播放器11的播放作业，于本实施例中，三个操作键111分别为前进(forward)、倒退(backward)及播放/暂停(play/pause)键，且播放键可用来控制车用随身MP3播放装置的开启与关闭，当使用者持续按住播放键一段时间，即可控制车用随身MP3播放装置的开启与关闭状态的变换。在本例中，车用随身MP3播放装置的外壳体10上设有一耳机孔18，可对应插设一耳机，当车内乘客并非全部都想听MP3音乐时，可接上耳机聆听音乐，避免干扰到其他乘客。In addition, the outer periphery of theouter shell 10 of the portable MP3 player for a car can be provided with three operation keys 111, which are used to control the playback operation of theMP3 player 11. In this embodiment, the three operation keys 111 are respectively forward (forward), Reverse (backward) and play/pause (play/pause) keys, and the play key can be used to control the opening and closing of the car portable MP3 player. When the user continues to press the play button for a period of time, the car portable MP3 can be controlled The transition between the on and off states of the playback device. In this example, theouter casing 10 of the portable MP3 player for the vehicle is provided with anearphone hole 18, and an earphone can be inserted correspondingly. interfere with other passengers.

前述车用随身MP3播放装置的外壳体10内可开设一电池座16以提供一备用电力，当车用随身MP3播放装置无法插设于电源插孔91时，例如驾驶人将其拔离插孔91并下车至车外，车用随身MP3播放装置仍可通过电池161所供应的电源来正常运作。A battery holder 16 can be provided in theouter casing 10 of the aforementioned car portable MP3 player to provide a backup power. 91 and get off to the outside of the car, the portable MP3 player for the car can still operate normally through the power supply supplied by the battery 161.

上述实施例仅为了方便说明而举例而已，本发明所主张的权利范围自应以申请专利范围所述为准，而非仅限于上述实施例。The above-mentioned embodiments are only examples for convenience of description, and the scope of rights claimed by the present invention should be based on the scope of the patent application, rather than limited to the above-mentioned embodiments.
