Abstract
The invention discloses a sing voice-changing device which is used for modulating a signal of an audio input device into a target signal and outputting the target signal into an audio output device. The sing voice-changing device comprises a voice-changing circuit and a voice-changing regulation device, wherein the voice-changing circuit is connected between the audio input device and the audio output device, and the voice-changing regulation device is connected with a control wire of the voice-changing circuit and used for inputting a target signal instruction.
Description
(1) technical field
The utility model relates to a kind of sing voice-changing device, particularly is applied to being used on the amusement equipment to adjust the device of audio signal.
(2) background technology
Karaoke is present popular recreational facilities, and also widespread uses of amusement equipment such as present VCD, DVD, but above-mentioned recreational facilities all have single function basically, the sound that the loudspeaker of promptly playing Karaoka broadcasts is singer's the actual sound and the morbid sound of corresponding music, in like manner, above-mentioned amusement equipment also are the primary sounds that has reflected on the CD disc.Raising along with people's living standard, simple sing or listen to the music with regard to the not simple needs of music, friend such as some male sex goes Karaoke to sing, recreational in order to increase, perhaps need some female voice singing styles, rely on popular singer's the change of voice, good effect can not be arranged, recreational reduction greatly.
(3) summary of the invention
Therefore, goal of the invention of the present utility model is to provide a kind of sing voice-changing device, is used for singer's sound is become the people's of all age group or different sexes sound, and is recreational to increase.
The technical solution adopted in the utility model is:
The utility model sing voice-changing device, be used for the signal of audio input device is modulated into echo signal and exports to audio output apparatus the change of voice regulating device that is used to import described echo signal instruction that it comprises the change of voice circuit that is connected between audio input device and audio output apparatus and is connected in this change of voice circuit controling line.
The utility model is incorporated into change of voice circuit between the present audio input device and audio output apparatus, between microphone and loudspeaker, some circuit based on frequency modulation technology have appearred in change of voice circuit at present, bias toward software, such as the change of voice function that is applied on the mobile phone, change of voice circuit in this programme can adopt the circuit based on frequency modulation technology, also can adopt the circuit of amplitude modulation.This programme can be exported different sound to singer's sound according to the echo signal instruction of change of voice regulating device input, increases recreational purpose.Its implementation is simple, regulates easily, can be widely used in Karaoke and wait in the amusement equipment.Because change of voice circuit is smaller, can directly be integrated on the microphone, and is easy for installation.
Above-mentioned sing voice-changing device, also comprise one in parallel with described change of voice circuit, have a branch road with the resistance R of described change of voice Circuit Matching, and on this branch road, be provided with a switch.
Above-mentioned sing voice-changing device, described change of voice circuit comprise A/D converter, modulator and the D/A converter that connects successively, and wherein adjuster is a filter capacitor, regulates its electric capacity by described change of voice regulating device and carries out the change of voice.
Above-mentioned sing voice-changing device, described filter capacitor are a plurality of, and are connected in parallel.
(4) description of drawings
Fig. 1 is a kind of structural representation of the utility model sing voice-changing device.
Among the figure: 1 refers to filter capacitor.
(5) embodiment
With reference to explanation accompanying drawing 1, the present embodiment sing voice-changing device, be used for the signal of audio input device is modulated into echo signal and exports to audio output apparatus, it is characterized in that: the change of voice regulating device that is used to import described echo signal instruction that it comprises the change of voice circuit that is connected between audio input device and audio output apparatus and is connected in this change of voice circuit controling line.
In order to obtain better entertainment effect, also comprise one in parallel with described change of voice circuit, have a branch road with the resistance R of described change of voice Circuit Matching, and on this branch road, be provided with a switch, thereby, can use simultaneously by two circuit in case of necessity, a people's sound class is same as two people and mixes performance.
For simplified structure, described change of voice circuit this programme preferably includes successively and to connect
A/D converter, modulator and D/A converter, wherein adjuster is a filter capacitor, regulates its electric capacity by described change of voice regulating device and carries out the change of voice, and used element is few, and change of voice effect is also good.
Described filter capacitor is a plurality of, and is connected in parallel, and can adopt and select the mode of electric capacity number to change electric capacity, for stepless adjustment, can select tunable capacitor.
Claims (4)
