Abstract
The invention relates to a record player whose disc is under the turntable, comprising turntable, disc, needle, needle arm, and disc seat, where the needle is at one end of the needle arm; and also comprising: suspension arm and balance block; one end of the suspension arm is fixed with the disc seat and the other end is fixed with the turntable; there is a certain distance between the turntable and the disc seat; the disc is arranged under the turntable and there is a fixing piece under the axis of the disc; the balance block is at the other end of the needle arm; the needle is under the disc and makes the needle contact with the disc through the balance block; in air suspending mode, arranging the disc on the needle and the needle slides under the disc, able to effectively make disc dustproof and keep tone quality of the disc for long time.
Description
Technical field
The present invention relates to a kind of electric phonograph, relate in particular to the arrangement of disc in this electric phonograph.
Background technology
Settle the mode of disc to be in the existing electric phonograph: disc is placed on the rotating disk in the electric phonograph, with dial rotation, stylus streaks in the groove of disc, and groove makes the stylus vibration, the shuttle belt dynamic pressure electric crystal of pin and produce electric signal, electric signal is converted to sound with loudspeaker after amplifier amplifies.But can there be following problem in the mode of this arrangement disc: the firstth, and disc easily is stained with dirt; The secondth, stylus is repeatedly friction in the disc groove, and time one length can cause groove wear, and the sound of emitting " is got out of tune ", is not durable.
Summary of the invention
The technical issues that need to address of the present invention have provided the electric phonograph of a kind of disc under rotating disk, are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes rotating disk, disc, stylus, stylus arm, disc base; Stylus is at an end of stylus arm; Also comprise: a suspension arm; Described suspension arm one end is fixedlyed connected with the disc base, and the other end is fixedlyed connected with rotating disk, between rotating disk and the disc base certain distance is arranged; Disc is placed in the below of rotating disk, and below the disc axle center fixture is arranged; A counterbalance weight, described counterbalance weight is at the other end of stylus arm; Stylus makes stylus contact with disc below disc and by counterbalance weight;
Compared with prior art, the invention has the beneficial effects as follows: by the mode of air suspension, disc is placed the top of stylus, and stylus can effectively realize on the one hand that in the disc slid underneath disc is dustproof, maintenance disc tonequality that on the other hand also can be permanent.
Description of drawings
Fig. 1 is a structural drawing of the present invention;
Fig. 2 is the structural drawing of pneumatic pump among Fig. 1;
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
By Fig. 1, Fig. 2 as seen: the present invention includes rotating disk 1, disc 8, stylus 6, stylus arm 5, disc base 9; Stylus 6 is at an end of stylus arm 5; Also comprise: a suspension arm 2; Described suspension arm 2 one ends are fixedlyed connected with disc base 9, and the other end is fixedlyed connected with rotating disk 1, between rotating disk 1 and the disc base 9 certain distance are arranged; Disc 8 is placed in the below of rotating disk 1, and below disc 8 axle center fixture 7 is arranged; A counterbalance weight 4, described counterbalance weight 4 is at the other end of stylus arm 5; Stylus 6 makes stylus 6 contact with disc 8 below disc 8 and by counterbalance weight 4;
Described fixture 7 can be made up of upper and lower two blocks of magnet; Last magnet is at rotating disk 1, and lower magnet is below disc 8;
Described rotating disk 1 and disc 8 close one sides can also comprise several apertures 11; Described aperture 11 links to each other with an evacuated air pump 3 by the connecting tube 12 that is placed in the suspension arm 2;
Described evacuated air pump 3 is placed in the suspension arm 2.
Rotating disk is positioned the centralized positioning axle, behind power supply opening, drives the evacuated air pump, and the absorption disc is finished normal rotation playing function; And stylus can upwards streak on the surface of disc by the balance of the counterbalance weight of the stylus arm other end, brings damage so just can for the groove of disc.
The mode of laying of disc is: disc is put into, after it is fixed on the rotating disk fixture.
Principle of the present invention is, works as electric power starting, and the evacuated air pump operation by air duct, is adsorbed on disc on the rotating disk, guarantees disc in the uniform rotation of centralized positioning axle, also has the fixation of counterbalance weight in addition, and duplicate protection guarantees that disc can not fall.
