Description
Technical field
The utility model belongs to loudspeaker field, particularly a kind of pull-type loudspeaker.
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, particularly the 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.
Utility model content
The utility model is in order to solve the problem, there is provided a kind of pull-type loudspeaker, micropkonic volume adjusting and switch can be realized by single thumb wheel, change conventional loudspeakers labyrinth, and loudspeaker both can with microphone wired connection, but also to be connected with microphone by wireless mode.
The technical scheme adopted is as follows, a kind of pull-type loudspeaker, comprise loudspeaker main body and impeller switch, described loudspeaker main body comprises housing and intraware, described intraware is fixedly installed in housing, described housing parts with opening, to hold thumbwheel switch, described thumbwheel switch is connected with intraware and protrudes to housing extension and forms thumb wheel sliding area, and described thumbwheel switch is respectively used to regulable control and amplifies volume, MP3 volume and loudspeaker switch.
Preferably, described thumbwheel switch is arranged on the upper right corner of housing and is threaded, so that stirring when holding loudspeaker.
Preferably, described intraware comprises loud speaker, display module, wireless receiving assembly and circuit board, described loud speaker, display module, thumbwheel switch are connected with circuit board with wireless receiving assembly, acoustic information is decoded and is sent through loud speaker after amplifying by circuit board, the display screen of display module is arranged on the front end face of housing, the wireless sound signals that described wireless receiving assembly sends for receiving wireless microphone, to realize Wireless amplification effect.
Preferably, described intraware comprises function button, for regulating loudspeaker function, housing arranges button through hole, described button and circuit board are electrically connected, described thumbwheel switch is connected with circuit board by potentiometer, and impeller switch is used for each function volume adjusting and loudspeaker switch, reaches thumb wheel control effects.
Preferably, described housing comprises procapsid and back casing, and procapsid sends hole with some sound, procapsid lid is located on back casing and forms cavity structure, to hold loudspeaker intraware, procapsid forms viewing area, back housing portion caves inward formation groove, so that placing battery.
Preferably, described back casing arranges fastener, fastener inserts the chute being arranged on back casing and is removably disposed on back casing, so that loudspeaker is hung on human body.
The beneficial effects of the utility model are: by changing the mode of loudspeaker volume adjusting, adopt thumbwheel switch formula adjusting knob, thumbwheel switch is connected with circuit board, realize volume adjusting effect, pull-type switch-mode regulation volume is convenient, tuning space can be reduced, also user's tuning is facilitated, and thumbwheel switch can also control micropkonic switch, very convenient, further, loudspeaker is with wireless receiving function, the voice signal of wireless microphone can be received, and do not need to add independent receiving system ability Received signal strength again, simple and easy, easy-to-use.
