Specific embodiment
Further to illustrate that the application is the technical means and efficacy reaching predetermined purpose and being taken, below in conjunction with attached drawing
And preferred embodiment, to specific embodiment, structure, feature and its effect according to the application, detailed description is as follows.Following
In explanation, what different " embodiment " or " embodiment " referred to is not necessarily the same embodiment.In addition, in one or more embodiments
Special characteristic, structure or feature can be combined by any suitable form.
In conjunction with shown in Fig. 1 and Fig. 3, the utility model discloses a kind of phonograph, includes at least: shock-absorbing support seat；Setting exists
Turntable 4, tone arm 9 and the pickup 8 positioned at 9 end of tone arm on shock-absorbing support seat for placing disc record and disc record being driven to rotate,
4 center of turntable is equipped with main shaft 5, and the upper end of the main shaft 5 is equipped with for disc record to be pressed on 4 town Shang Die 6 of turntable.Cause
This, the upper end that disc record is set in main shaft 5 is placed on turntable 4 and drives rotation by turntable 4, thus the stylus on pickup 8
The piece line sounding of friction disc.
Wherein, the specific structure and working principle of main shaft 5, refers to Chinese patent application CN2017206637205's
Technical solution, this will not be detailed here.
Further combined with shown in Fig. 2 and Fig. 4.Shock-absorbing support seat specifically includes multiple columns 1, the bottom being fixed on column 1
Plate 2 and the chassis 3 on bottom plate 2, and damping is equipped between each column 1 and chassis 3.The damping specifically wraps
Elastic portion 13 and damping elastic slice 15 are included, upper end and the column 1 of the elastic portion 13 are fixedly linked, the first end of damping elastic slice 15
It suspends in midair and is arranged with the lower end of elastic portion 13, the second end of the damping elastic slice 15 is equipped with fixation hole 151, solid using screw etc.
