Abstract
The utility model discloses a multifunctional radio that is provided with a plurality of power supply modes to be selected and is capable of continuously supplying power and largely prolonging listen and play time of the radio. The multifunctional radio comprises a casing, a band select switch, a channel selection tuning knob, a power supply change over switch, a control circuit board, a buck rectifier module, an AC power port, a lead-acid battery, a lithium battery and a dry battery; the lead-acid battery, the lithium battery and the dry battery are respectively connected with the control circuit board through the power supply change over switch; the AC power port is connected with the control circuit board through the buck rectifier module; the multifunctional radio also comprises a function switch and an MP3 player, and the MP3 player is connected with the control circuit board; and the multifunctional radio further comprises an LED lighting lamp and a lighting switch. Compared with a traditional radio, the multifunctional radio has four power supply modes including the lead-acid battery, the lithium battery, the dry battery and the AC power, either of which can be optionally selected, the listen time can be largely prolonged, emergency lighting and MP3 play can also be performed, and the multifunctional radio is economical and practical and especially used in regions which are frequently powered off.
Description
Technical field
The utility model relates to a kind of broadcast receiver, and particularly a kind of have plurality of optional and select the late model radio of supply power mode.
Background technology
In the area of frequent power-off, economic development is relatively slow, in order to understand in time extraneous variation, with local information, this as broadcast receiver is economical and practical a kind of electronic product that can receive anywhere or anytime again information, be popular, still, existing a broadcast receiver adopts one of dry cell and alternating current to power, but, in the area of frequent power-off, once power-off, alternating current cannot use, can only use dry cell, dry cell power supply is not lasting, and long-term use cost is high, and can cause larger environmental pollution.
Utility model content
The purpose of this utility model is: a kind of selective multi-functional radio of multiple supply power mode that has is provided, and sustainable power supply, extends the wireless reproduction time of listening to greatly.
The technical solution adopted in the utility model is: comprise casing, range switch, channel selection tuner knob, it is characterized in that: also comprise for electrical switch, control circuit board, step-down rectifier module, alternating current port, lead-acid battery, lithium battery, dry cell, lead-acid battery, lithium battery, dry cell are respectively through being connected with control circuit board for electrical switch, and alternating current port is connected with control circuit board through step-down rectifier module.
The utility model is broadcast listening not only, and has MP3 playing function, therefore, comprises for MP3 and play function switch, the MP3 player changed between radio reception, and MP3 player is connected with control circuit board.
The utility model also has function of emergency illumination, therefore, comprises LED illuminating lamp, lighting switch.
The utility model is easy to carry, and therefore, comprises a handle, and handle two ends are connected with casing.
Good effect of the present utility model is: particularly in the frequent area of power-off, more general broadcast receiver, the utility model has four kinds of supply power modes: lead-acid battery, lithium battery, dry cell, the optional one of alternating current, listening period extends greatly, and can also emergency lighting, can also play MP3, economical and practical, easy to carry.
