Abstract
A PDA with an ear phone and a loudspeaker completely brings the diminutive capacity of the PDA into effect, having the advantage of convenient carrying. The PDA is capable of processing voice communication and listening to music and medium reports in the noisy environment.
Description
Along with the progress of science and technology, the function of PDA (personal digital assistant) is more and more perfect.The PDA that integrates functions such as network, communication, speech processes will be that trend becomes.Like this, under the situation of present no external earphone and microphone, the use of PDA will be restricted greatly.
Purpose of the present invention is exactly to having the leading design of above-mentioned functions PDA, realize the output and the input of voice signal, make the end user PDA can be put in pocket, only transmit voice with earphone and microphone, do not need hand-held PDA, highlight the ease of use of the utility model so that end user's both hands can carry out other work.
To achieve these goals, the present invention proposes on the basis of present PDA and add phonetic entry, output port or a module.By this port or module can be wired with the outside microphone, earphone, or wireless microphone, earphone carry out the transmission process of voice signal.
With reference to the accompanying drawings most preferred embodiment of the present invention is described.
Fig. 1 is a schematic diagram of the present utility model.
As shown in Figure 1, of the present utility model being characterised in that added an earphone 21 and pocket microphone 22 on the PDA 10, through its lead-in wire 23 and plug 24, can be plugged on the voice output port 11 set on the PDA 10, and be linked to be same system with PDA.
In sum, set up earphone and microphone on the PDA of the present utility model, make the end user in use, can be in pocket with the PDA pendulum, receive and the transmission voice signal with earphone and microphone, both hands needn't be held PDA just can carry out voice transfer, greatly facilitates the function use of abundant PDA day by day.
Should be appreciated that above explanation just in order to describe embodiments of the invention, rather than to any qualification of the present invention.Interest field of the present invention has claim subsequently to limit, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to the covering scope of patent of the present invention.
