CN201259787Y - MP3 player - Google Patents

Abstract

The utility model relates to an MP3 player whose control switch is a rotary type. The MP3 playing circuit is located in a circular casing. The upper and lower shells of the circular casing form a circular track. Advantages: It not only has the function of switch control, but also has the function of celestial body teaching.

Description

The MP3 player

Technical field

It is revolving MP3 player that the utility model relates to a kind of gauge tap, belongs to the MP3 player and makes the field.

Background technology

Existing MP3 player mostly adopts touch-key single by form on the key control, is inconvenient to use; Secondly, do not have the function of teaching.

Summary of the invention

Purpose of design: avoid the weak point in the background technology, the design ball type switch is around the MP3 player of circular shell periphery rotary switch.

Design proposal: to achieve these goals.MP3 switch control button be distributed on the periphery of circular casing and with the design that rotary knob is complementary, be principal character of the present utility model.The purpose of doing like this is: rotary knob both can have been controlled the switch of MP3 easily, can play the purpose of celestial body teaching along the circular casing orbit rotation again.

Technical scheme: the MP3 player, the MP3 playing circuit is positioned at circular casing, and MP3 switch control button is distributed on the periphery of circular casing and with rotary knob and is complementary, and the last lower casing that rotary knob is positioned at by circular casing constitutes circuit orbit.

The utility model is compared with background technology, has both had the function of switch control, has the function of celestial body teaching again.

Description of drawings

Fig. 1 is a rotary switch MP3 player synoptic diagram.

Fig. 2 constitutes structural representation in the circuit orbit by the last lower casing of circular casing among Fig. 1.

Embodiment

Embodiment 1: with reference to Fig. 1 and 2.The MP3 player, the MP3 playing circuit is positioned at circular casing 1, MP3 switch control button is distributed on the periphery of circular casing 1 and with rotary knob 2 and is complementary, the last lower casing that rotary knob 2 is positioned at by circular casing 1 constitutes circuit orbit 3, the trigger head of rotary knob 2 is the piano type trigger head, is used to trigger be positioned at opening or closing of MP3 switch operating key on circular casing 1 periphery.Rotary knob 2 is the spherical of magnetic tape trailer.During as teaching, circular casing 1 is equivalent to the sun or the moon, and spherical rotary knob 2 is equivalent to the earth.

What need understand is; though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; it is simple description to the utility model mentality of designing; rather than to the restriction of mentality of designing of the present utility model; any combination, increase or modification that is no more than the utility model mentality of designing all falls in the protection domain of the present utility model.

Claims (3)

1. An MP3 player, the MP3 player circuit is located in a circular casing, and its feature is: the MP3 switch control buttons are distributed on the circumferential surface of the circular casing and matched with the rotary button, and the rotary button is located on the circular machine. The upper and lower shells of the shell form a circular orbit. 2. The MP3 player according to claim 1, wherein the trigger head of the rotary button is a keyboard trigger head. 3. The MP3 player according to claim 1 or 2, characterized in that: the rotation button is in the shape of a ball with a tail.
