Description

The audio frequency adjusting knob
Technical field
The present invention relates to a kind of audio frequency adjusting knob.
Background technology
Audio-frequence player device is had relatively high expectations to the potentiometer knob smooth operation, because of when rotation has some setbacks, easily produces noise, produces noise.The potentiometer manufacturer of specialty is that metal shaft potentiometer or knob-style potentiometer etc. have all reached the degree of precision requirement at present, but because potentiometer is weldingly fixed on circuit board usually, simultaneously due to product appearance moulding demand, configuration design will meet the consumption grade demand of different crowd, at the operation knob of the outside design of product different shaping, so potentiometer is connected direct affect operating handle and potentiometer start stationarity with the design between external knob.
Summary of the invention
In view of this, be necessary to provide a kind of when guaranteeing the knob rotation periphery tolerance clearance unanimously can overcome again the audio frequency adjusting knob of the welding position inconsistency of potentiometer and circuit board.
A kind of audio frequency adjusting knob, be arranged on electronic installation and be used for regulating audio frequency, described electronic installation comprises protecgulum, bonnet and is contained in protecgulum and the circuit board of bonnet institute restriceted envelope, described audio frequency adjusting knob comprises: shell fragment, comprise body and be arranged on the elastic arm on described body, between described elastic arm and described body, thering is gathering sill; Handheld Division, with described shell fragment phase riveted to be assemblied on described protecgulum; Potentiometer, be welded on described circuit board; And connecting rod, being fixed on described potentiometer, described connecting rod has projection, and described projection stretches in described gathering sill, and described elastic arm orders about to drive described link motion and then drives described potentiometer rotation for the external force be applied on described Handheld Division.
Compared to prior art, the Handheld Division of the audio frequency adjusting knob of the present embodiment is assemblied on protecgulum by shell fragment riveted mode, can guarantee the consistance in Handheld Division and front cover match gap; The elastic arm of shell fragment is controlled spinning force, can reduce the manufacturing accuracy of part, and can guarantee the consistance of spinning force.

Embodiment
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the audio frequency adjusting knob 40 that the embodiment of the present invention provides is arranged on electronic installation 100 and is used for regulating audio frequency, for example, and volume, channel (shortwave, long wave or medium wave) etc.
Electronic installation 100 comprise protecgulum 10, bonnet 20 and be arranged on protecgulum 10 and 20 restriceted envelopes of bonnet in circuit board 30.Be provided with a plurality of circuit orbits 11 on protecgulum 10, be used for matching with audio frequency adjusting knob 40.
Certainly, the number of circuit orbit 11 is different according to the needed audio frequency adjusting knob 40 of electronic installation 100, for example, while only needing an audio frequency adjusting knob 40, has a circuit orbit 11.
Audio frequency adjusting knob 40 comprises Handheld Division 41, shell fragment 42, potentiometer 43, connecting rod 44 and screw 45.
Handheld Division 41 is assemblied on protecgulum 10 by the riveted mode with shell fragment 42.Handheld Division 41 has respectively force section 410 and grip unit 411 on relative two surfaces, and force section 410 is towards electronic installation 100 outsides, and grip unit 411 is towards electronic installation 100 inside.Force section 410 presents " one " font to facilitate the application of force, and grip unit 411 is the crannied right cylinder of middle tool, because grip unit 411 has crack, therefore grip unit 411 is in having in the radial direction certain elasticity.External force puts on Handheld Division 41 so that Handheld Division 41 by force section 410 and can rotate, and grip unit 411 has elasticity and is used for and shell fragment 42 phase riveteds.
Certainly, in other embodiments, force section 410 also can be other shape that facilitates the application of force, for example, and serpentine.
Shell fragment 42 comprises the body 420 of a circle, has three elastic arms 421 that uniformly-spaced arrange on body 420, the circumferencial direction of the parallel body 420 of the extending direction of elastic arm 421.All there is a hemisphere jut 422 on each elastic arm 421, the projection 422 be positioned at protecgulum 10 circuit orbit 11 so that shell fragment 42 can rotate relative to protecgulum 10.All form a gathering sill 423 between each elastic arm 421 and body 420.In addition, also have the through hole 424 matched with the grip unit 411 of Handheld Division 41 on body 420, then grip unit 411 stretches in through hole 424 replys original shape body, thereby Handheld Division 41 and shell fragment 42 riveteds are fixed.
Potentiometer 43 is welded on circuit board 30 Shang,Qi centers and has a rotating shaft 430, and the rotation of rotating shaft 430 can drive potentiometer 43 and rotate to realize the audio frequency adjusting.
Connecting rod 44 is fixed on by screw 45 in the rotating shaft 430 of potentiometer 43, and connecting rod 44 has a projection towards shell fragment 42 440, and projection 440 inserts in the gathering sill 423 of shell fragment 42.
Certainly, connecting rod 44 also can be fixed on potentiometer 43 by alternate manner, for example, and welding.
Putting on external force on Handheld Division 41 projection 440 by the gathering sill 423 on shell fragment 42 and connecting rod 44 passes to the rotating shaft 430 that connecting rod 44 drives potentiometer 43 and rotates, in rotary movement, thereby the different parts of potentiometer 43 and circuit board 30 are realized the audio frequency regulatory function.
The Handheld Division 41 of the audio frequency adjusting knob 40 of the present embodiment is assemblied on protecgulum 10 by shell fragment 42 riveted modes, can guarantee the consistance of Handheld Division 41 and protecgulum 10 tolerance clearances; The elastic arm 421 of shell fragment 42 is controlled spinning force, can reduce the manufacturing accuracy of part, and can guarantee the consistance of spinning force; The gathering sill 423 of shell fragment 42 coordinates to drive potentiometer 43 with connecting rod 44, but the positioning error while overcoming potentiometer 43 welding and the assembly error of correlated parts.
Be understandable that, those skilled in the art also can do other variation etc. and be used in design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
