Embodiment Construction

[0014] see figure 1 , a preferred embodiment of the present invention provides a portable electronic device, which can be a mobile phone, MP3 and so on. In this embodiment, a mobile phone 100 is taken as an example for illustration. The mobile phone 100 includes a body 10 and a sound amplifying device 30 mounted on the body 10 .

[0015] The main body 10 is provided with a plurality of sound holes 11 . The sound amplifying device 30 includes a base 31 , a horn 33 and a sealing portion 35 . The base 31 is an injection molded plastic body made of polypropylene (PP), polyamide (PA), polycarbonate (PC), polyethylene terephthalate (PET) and polymethyl methacrylate (PMMA). ) and other plastic materials. The base 31 is generally in the shape of a rectangular plate, and two ends of the base 31 are respectively extended with a generally "L"-shaped buckle portion 311 for clamping two opposite edges of the body 10, and then assembling the base 31 to the base. On the main body 10. T...

Abstract

The invention provides a sound amplification device and a portable electronic device employing the same. The sound amplification device includes a base and a loudspeaker mounted on the base, wherein the base is made of polypropylene (PP), polyamide (PA), polycarbonate (PC), polyethylene terephthalate (PET) or polymethyl methacrylate (PMMA), and the loudspeaker is made of rubber or silica gel. The sound amplification device is portable, and can effectively reduce the assembly procedures and lower the manufacture costs.

Description

technical field [0001] The invention relates to a sound amplifying device and a portable electronic device with the sound amplifying device. Background technique [0002] In order to increase the external volume of portable electronic devices such as mobile phones and MP3 players, various passive loudspeakers have appeared on the market. One of the passive loudspeakers consists of a base and a horn made of soft materials (such as silicone, rubber, etc.). In order to tightly wrap the portable electronic device, the base of this passive loudspeaker must be made relatively large, which is inconvenient for the passive loudspeaker to be carried around. Another type of passive loudspeaker is composed of a base and a horn made of hard materials (such as PC, PMMA, PA, etc.). This kind of passive loudspeaker needs to add a foam between the base and the sound hole on the portable electronic device, which will inevitably increase the production cost of the passive loudspeaker. Cont...
