Abstract
A movement structure of a phonograph comprises a rotating disk and a tone arm. The rotating disk is provided with a transmission apparatus. The tone arm is arranged above the rotating disk in a horizontally swinging manner through a returning arm. The movement structure is characterized in that, the rotating disk, the transmission apparatus, the tone arm and the returning arm are all arranged on a wooden pedestal. The pedestal is provided with a recessed room for accepting the transmission apparatus. The pedestal is also provided with a pore space for installing and positioning the tone arm and the returning arm. The movement structure provided by the utility model has the advantages that, the rotating disk and the tone arm adopt a split type design, enabling the structures of the rotating disk and the tone arm to be diversified and customized; after the rotating disk and the tone arm are designed in the split type, the rotating disk and the tone arm are respectively arranged on the pedestal, hence the rotating disk is protected from influence caused by the swinging tone arm, integral vibration of the rotating disk is reduced and tone quality of a disc is increased. The rotating disk and the tone arm are both embedded in a chassis, an integrated structure is formed, enabling transportation and movement to be stable and firm. Shake and shift are prevented and further product quality is increased.

For this reason, people have improved the tone arm structure of disc machine, and after a disc has been sung, tone arm upwards lifts and be recovered to reset mode automatically, has improved further disc machine performance, has extended the serviceable life of disc machine.As the patent No. Chinese utility model patent < < electronic type electric phonograph that is ZL88214622.X returns arm > > midway, a kind of electronic device for phonograph halfway pickup-returning is disclosed; this patent has solved current commercially available electric phonograph need to increase the problem of returning arm function midway, as long as add an integrating circuit, an automatic reset switch and an electromagnet just can realize the function that it returns arm and shutdown midway in electric phonograph.But, electromagnet has been used in returning in arm assembly of this patent, mounting distance between electromagnet and spinal plate, gear has certain requirement, electromagnet reliably need to be positioned on the position of designing requirement, higher to installation requirement, if product needed long-distance transport, easily causes electromagnet dislocation in transportation, and then affect the normal use of disc machine; And electromagnet is owing to having magnetic, disc machine is easily subject to external interference and destroys the precision that disc machine returns arm assembly in transportation and use procedure, reduces the reliability that disc machine uses.
In addition, current electric phonograph rotating disk and tone arm are all that integral molding is on a working of plastics, make one-piece construction comparatively stiff, the profile variation of rotating disk and tone arm is less, secondly, the motor of auto back arm function is installed and because being subject to the space constraint of working of plastics, is difficult to arrange, and, the revolution action of tone arm is easy to cause the vibration of rotating disk, and then affects the broadcasting tonequality of disc record.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, to provide a kind of simple in structure and can effectively improve the cassette mechanism structure of the electric phonograph of disc tonequality.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of cassette mechanism structure of electric phonograph, include rotating disk and tone arm, described rotating disk has gearing, described tone arm can be arranged at the top of described rotating disk by returning arm assembly horizontal hunting, it is characterized in that: described rotating disk, gearing, tone arm and time arm assembly are all arranged on wooden base, described base offers the alcove that can hold described gearing, also offers and can and return the vestibule that arm assembly is installed location for described tone arm on described base.
Gearing can be various structures of the prior art, as gear drive or belt pulley transmission or linkage assembly etc., for simplified structure, as preferably, simply, described gearing can be following structure, this gearing includes motor and belt, between described rotating disk and motor, by described belt, be connected, the transmission shape of the shape of described alcove and described belt is suitable, and, described rotating disk has center rotating shaft, on described alcove, also offer and can wear the first through hole of described center rotating shaft and the second through hole that can accommodating described motor.
In order to make the installation of belt more reliable, as preferably, the bottom of described rotating disk has annular boss, and described motor has motor shaft, between described motor shaft and annular boss by described belt tension and realize transmission.
In order to make volume more compact, reduce component structural, reduce and produce and assembly cost, as preferably, described cassette mechanism structure also includes substrate, and described time arm assembly includes drive unit, and described motor, center rotating shaft and drive unit are all arranged on described substrate, and the cover of driver of described drive unit and described substrate are one-body molded.
In order to facilitate mounting limit, as preferably, described vestibule is rectangular, and the two ends of described vestibule are respectively arranged with the step surface for described time arm assembly axial limiting.
Compared with prior art, the utility model has the advantage of: rotating disk and tone arm have adopted split-type design, make the structure of rotating disk and tone arm can be more diversified and personalized; After rotating disk and tone arm split-type design, be arranged on respectively on base, the impact of avoiding tone arm to swing back and forth on rotating disk, reduces the body vibration of rotating disk, thereby improves the acoustical quality of disc; Rotating disk and tone arm are all embedded on chassis, form integral structure, make transportation and mobile more stable firm, prevent from rocking displacement, further improve the quality of products.
