Abstract
The utility model provides an intelligent hand mobile with a karaoke function built therein, comprising an intelligent hand mobile, a karaoke circuit module and an earphone power amplifier, wherein bidirectional communication connection is established between the karaoke circuit module and the intelligent hand mobile, the output end of the karaoke circuit module is connected with the earphone power amplifier, and the karaoke circuit module comprises a plurality of AD converters, a digital signal processor and a DA converter. The intelligent hand mobile can realize various professional effects such as echo processing, reverberation processing, equalization processing, voltage limit processing, and squeaking inhibition processing, etc., through adding a module with the karaoke functional built therein, thereby enabling the hand mobile to have a karaoke function, and greatly increasing the market competitiveness of hand mobile service providers.
Description
Technical field
The utility model relates to field of mobile phones, relates in particular to a kind of smart mobile phone of built-in karaoke function.
Background technology
At present, the standard audio in the smart mobile phone is configured to built-in microphone, a pair of Microspeaker and the earphone socket below the frequency band 8KHz, and earphone socket has also comprised an external microphone, can connect the microphone/ear speaker device of one.
But this configuration is because the restriction of hardware condition; The microphone part can not realize echo (ECHO), reverberation (REV) balanced (EQ) and other specialty type effect; Even increase these functional effects through inner software processes; Because there are defectives such as frequency response is narrow, dynamically little, background noise is big in quality, the configurable limit of microphone part itself, still can't satisfy high-quality Karaoke amusement requirement.
Summary of the invention
The purpose of the utility model is to provide a kind of smart mobile phone of built-in karaoke function, and this mobile phone has the effect of playing the Karaoke audio, can satisfy the needs of home entertaining.
The purpose of the utility model realizes through following technical scheme.
A kind of smart mobile phone of built-in karaoke function comprises: smart mobile phone, Karaoke circuit module and earphone power amplifier; Said Karaoke circuit module is set up two-way communication with smart mobile phone and is connected, and the output of said Karaoke circuit module links to each other with the earphone power amplifier, and said Karaoke circuit module comprises multi-channel A transducer, digital signal processor and DA transducer.
Preferably, said earphone power amplifier is a D class earphone power amplifier, and it comprises 2 covers or the above earphone accessory power outlet configuration of 2 covers.
Preferably, also comprise single-chip microcomputer, said single-chip microcomputer is used for control Karaoke circuit module work and establishes a communications link with smart mobile phone.
The utility model compared with prior art; Beneficial effect is: the utility model is through increasing a built-in karaoke functional module in smart mobile phone; Can realize microphone echo processing, reverberation processing, equilibrium treatment, the processing of pressure limit, the specialty type effects such as suppressing processing of uttering long and high-pitched sounds; Make mobile phone have Kara OK function, promoted the market competitiveness of mobile phone operators greatly.
Description of drawings
Fig. 1 is the smart mobile phone theory diagram of the utility model built-in karaoke function.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also shown in Figure 1ly, the smart mobile phone of the utility model built-in karaoke function comprises: smart mobile phone 1, single-chip microcomputer 2, Karaoke circuit module 3, earphone power amplifier 4; Karaoke circuit module 3 is set up two-way communication with single-chip microcomputer 2 and smart mobile phone 1 respectively and is connected, and single-chip microcomputer 2 is used for 3 work of control Karaoke circuit module and communicates by letter with smart mobile phone 1 foundation, and the output of Karaoke circuit module 3 links to each other with earphone power amplifier 4.
Wherein, Karaoke circuit module 3 comprises multi-channel A transducer, digital signal processor (DSP), DA transducer, 2 tunnel (or more than 2 tunnel) microphones (1,2) input; Through AD converter separately; With analog-signal transitions is digital signal, is input to digital signal processor (DSP), accomplishes microphone and presses processing such as limit processing, equilibrium treatment, time-delay echo, reverberation processing, the inhibition of uttering long and high-pitched sounds; Simultaneously; The audio output signal of cell phone system also gets into DSP through AD converter (if analog signal) or direct (if digital signal); Disappear song, rising-falling tone, equilibrium, pressure limit, etc. processing such as loudness afterwards mix and export the DA transducer to microphone signal, be analog signal with digital signal transition, output to the earphone power amplifier or be directly inputted to mobile phone; Earphone power amplifier lug machine (1,2) output.
Wherein, the audio output signal of cell phone system is sent cell phone system back to and is done the recording processing after DSP handles.
In the utility model, the earphone power amplifier is a D class earphone power amplifier, and it comprises 2 covers or the above earphone accessory power outlet configuration of 2 covers.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
