Multifunctional sound box

Abstract

The invention discloses a multifunctional sound box. The multifunctional sound box comprises a box body, and a circuit mainboard and a loudspeaker, a radio function module, a record playing device anda compact disk playing device which are electrically connected with the circuit mainboard are arranged in the box body, wherein the record playing device is used for playing a record, and the compactdisk playing device is used for playing compact disks; the box body comprises a surface plate arranged at the front end, a station tuning rotary knob is arranged on the outer side of the surface plate, a rotating shaft is fixed to the channel tuning rotary knob, a tuning potentiometer which is electrically connected with the circuit mainboard and used for selecting a radio station is arranged onthe circuit mainboard, a rotor shaft capable of selecting the station during rotating is arranged on the tuning potentiometer, and a gear pair for allowing the rotating shaft and the rotor shaft to achieve reducing transmission is arranged between the rotating shaft and the rotor shaft; and a button switch capable of upwarping and downwarping to power on and power off a power supply is arranged onthe inner side of the surface plate, a safety switch which is exposed to the outer side of the surface plate and can push the button switch to upwarp and downwarp when being pushed up and down is hinged to the surface plate, and the button switch and the safety switch are made of insulating materials. The multifunctional sound box is simple in structure, good in radio tuning precision and securein use.

Description

【Technical field】 [0001] The invention relates to a multifunctional sound box. 【Background technique】 [0002] At present, most of the functional speakers on the market have the radio function. For users in different countries, especially foreign users, many users still like to play records or CDs. When users need to listen to radio, play records and CDs, they often need to purchase radios, Record players and DVD players, etc., cost a lot and take up space in the home. [0003] Moreover, the selection of radio stations is generally carried out by directly rotating the tuning potentiometer through the tuning knob. The tuning accuracy is poor, and it is often necessary to repeatedly adjust within a range for a radio station. [0004] In addition, the power switch is generally a button switch, which is connected to the power supply, and the finger directly touches the button switch for operation. Because the power switch is prone to arc or leakage, or many times the finger is ...

When users need to listen to radio, play records and CDs, they often need to purchase radios, Record players and DVD players, etc., are expensive and take up space in the home

[0003] Moreover, the selection of radio stations is generally carried out by directly rotating the tuning potentiometer through the tuning knob. The tuning accuracy is poor, and it is often necessary to repeatedly adjust within a range for a station.

[0004] In addition, the power switch is generally a button switch, which is connected to the power supply, and the finger directly touches the button switch for operation. Because the power switch is prone to arc or leakage, or many times the fingers are not dry, it is easy to be electrocuted during operation. There are certain security risks
