Description
Technical field
The utility model belongs to electronic device field, and particularly a kind of Single button amplifies.
Background technology
Loudspeaker, as the term suggests amplified by sound exactly, the farther meaning of propagation, the micropkonic sound penetration of relative audio amplifier is stronger.Initial loudspeaker, use electron tube, bulky, weight is not light.Along with electronic component is constantly microminiaturized, integrated, Portable loudspeaker also runs and gives birth to, though volume is little, sound is not inferior at all.Portable loudspeaker refers to and is easy to carry eaily, mostly possesses small volume, clear a kind of public address set simple to operate.Nowadays micropkonic level setting switches structure comparison is single, conventional loudspeakers, universal through market in recent years, homogeneity competition brings price blood to spell, make enterprise more and more bias toward product cost and think little of quality, the particularly difference of volume adjusting mode, product structure not only can be caused complicated, but also make noise noise increasing, bring to user's physical and mental health and to a certain degree damage, traditional loudspeaker volume adjustment knob function ratio is more single, can only regulate the volume of individual feature pattern, can not satisfy the demands.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of Single button loudspeaker, single knob and each function volume adjustable.
The utility model by the following technical solutions, a kind of Single button loudspeaker, comprise loudspeaker main body and single volume adjustment knob, described loudspeaker body comprises housing and intraware, described single volume adjustment knob comprises button cap and potentiometer, button cap to be arranged on housing and to be connected with potentiometer, and described potentiometer is connected with intraware, and Single button volume adjustment knob is used for control and amplifies volume, MP3 volume and loudspeaker switch.
Described button cap comprises first and screws portion and second and screw portion, first screws portion and second screws that portion is rotating to be connected, so that volume is finely tuned, first screws surface, portion arranges some projections, so that screw regulate volume time anti-skidding, second portion that screws is connected with potentiometer, screws first and screws portion, finely tune second simultaneously and screw portion, fine-tuning each function volume.
Preferably, described intraware comprises loud speaker, display module, wireless receiving assembly and circuit board, described loud speaker, display module are connected with circuit board with wireless receiving assembly, described intraware is fixedly installed in housing, the display screen of display module is arranged on the upper surface of housing, the wireless sound signals that described wireless receiving assembly sends for receiving wireless microphone, to realize Wireless amplification effect.
Preferably, described housing comprises procapsid and back casing, and described procapsid removably covers to be located on back casing and forms cavity structure, and described intraware is fixedly installed in cavity structure, described procapsid comprises front shroud, so as loud speaker amplify after sound send.
Preferably, described back housing portion caves inward, and forms a groove so that placing battery, and groove arranges one and the dismountable groove lid of back casing.
The beneficial effects of the utility model are: by changing the mode of loudspeaker volume adjusting, adopt single volume adjustment knob, simultaneously, single volume adjustment knob comprises turns round cap and potentiometer, potentiometer is connected with the assembly of loudspeaker inside, realize volume adjusting effect, loudspeaker function is more, therefore single volume adjustment knob can be adopted to regulate the volume of difference in functionality, and volume adjustment knob can also control micropkonic switch, compare traditional loudspeaker to need independently to arrange mains switch, the utility model obviously has more practicality and novelty.
