Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1 to 4, the portable electronic device comprises a fixing frame 1, sound units 2 are arranged at two ends of the fixing frame 1, and an elastic sleeve 3 is sleeved on a frame body of the fixing frame 1 between the two sound units 2.

The elastic sleeve 3 is located the cover body of the inboard of mount 1 and has been seted up the groove of making an uproar 4 of making an uproar, and the groove of making an uproar 4 has been seted up a plurality of sound holes of inhaling in the side of keeping away from mount 1, and inhale the sound hole and run through to the inboard surface of elastic sleeve 3, and the elastic sleeve 3 is kept away from the groove of making an uproar 4 one side and has been seted up matched with slope guide surface 5.
