Described controller is connected with described switching device, controls the first audio frequency output dress described in described switching means into conduction
Put, described switching device and described power amplifier are linked in sequence the first path formed；Or it is defeated to turn on described second audio frequency
Go out device, described switching device and described power amplifier be linked in sequence formed alternate path.
Embodiment of the present utility model provides the benefit that:
In such scheme, by receiver and speaker being shared same power amplifier, and increase a switching device, logical
Cross controller control switching device when handle is conversed, conducting power amplifier and receiver carry out audio frequency output；At hand-free call
Or when playing music/video, conducting power amplifier and speaker carry out audio frequency output.Program simple in construction, it is easy to real
Existing, improve loudness and the tonequality of receiver output audio frequency, meet Consumer's Experience, and the layout of beneficially printed circuit board.

Detailed description of the invention
It is more fully described exemplary embodiment of the present utility model below with reference to accompanying drawings.Although accompanying drawing shows this
The exemplary embodiment of utility model, it being understood, however, that may be realized in various forms this utility model and should be by not here
The embodiment illustrated is limited.On the contrary, it is provided that these embodiments are able to be best understood from this utility model, and energy
Enough complete for scope of the present utility model is conveyed to those skilled in the art.
Embodiment
As it is shown in figure 1, this utility model embodiment provides a kind of terminal unit, including: coder 1, power amplification
Device the 2, first audio output device the 3, second audio output device 4, switching device 5 and controller 6；Wherein, power amplifier 2 with
Coder 1 electrically connects；First audio output device 3 electrically connects with switching device 5；Second audio output device 4 and switch dress
Put 5 electrical connections；Controller 6 is connected with switching device 5, controls switching device 5 and turns on the first audio output device 3, switching device 5
With power amplifier 2 be linked in sequence formed the first path；Or conducting the second audio output device 4, switching device 5 and power
Amplifier 2 be linked in sequence formed alternate path.
In this embodiment, when terminal unit produces voice signal under handle call mode (receiving audio frequency by receiver)
Time, voice signal warp knit decoder 1 processes, and controller 6 controls switching device 5 and turns on the first audio output device 3 (example
As: receiver) and power amplifier 2 place path, and carry out audio frequency output by the first audio output device 3, it is achieved the first sound
Frequently the purpose that output device 3 loudness increases；When terminal unit produces under music/video play mode or handsfree talk mode
During voice signal, voice signal warp knit decoder 1 processes, and controller 6 controls switching device 5 and turns on the second audio frequency output dress
Put 5 (such as: speaker) and power amplifier 2 place path, and carry out audio frequency output by the second audio output device 5.Should
Scheme is simple, improves receiver and carries out loudness and the tonequality of audio frequency output, and disclosure satisfy that winding displacement on printed circuit board
