Abstract
The utility model relates to a handset with the reverberation function, which comprises a signal delay control circuit with a signal delay controller 20, a radio signal processing unit 30 connected with the signal delay controller 20, and a broadcast signal processing unit 40 connected with the signal delay controller 20, wherein, the signal delay controller 20 has a sound input signal that a microphone 51 receives the sound of the user, and then the sound is inputted to the signal delay controller 20 again; the sound import signal is delayed, and then is output to the broadcast signal processing unit 40 again. The broadcast signal processing unit 40 is connected with a handset earphone signal end 12, so the delayed sound signal and the music signal in the handset are mixed, and then are broadcast to the outside by an earphone 50. The user can hear the sound signal with reverberation effect by the earphone 50, and just as stay in the KTV.
Description
Technical field
The utility model is a kind of mobile phone with reverberation function, refers in particular to a kind of mobile phone that reverberation effect is arranged when cooperating music to sing.
Background technology
At present, along with the decline of the increasing of cell-phone function, price, the use of mobile phone is more and more universal.The call function of mobile phone has not been its unique attraction.Each mobile phone manufacturer buys new cell-phone again in order to attract masses on the market of so popularizing, and there's no one who doesn't or isn't racks one's brains and caters to the various demands of most consumers, releases various trendy mobile phones.Technically, mobile phone not only can be updated aspect mechanism, but also can be used as a network terminal machine use of connected network.Utilize network, the information of wanting can arbitrarily be uploaded or download to mobile phone on the net, as the convenience of computer.By this, partly mobile-phone manufacturers utilize online music download service that Internet service provider provides, like the hobby of singing having designed, provide the mobile phone with Kara OK function at masses.Because mobile phone is easy to carry, the function of its Karaoke can be downloaded new song easily at any time, and the consumer just can enjoy the enjoyment of Karaoke at any time.But the present mobile phone that Kara OK function is arranged is a playing back music, and the user follows the screen humming, there is no as the sensation of in KTV, playing Karaoka, therefore, some blemish in an otherwise perfect thing that shows.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of mobile phone with reverberation function is provided, can will broadcasts by loud speaker again after its mixing simultaneously by microphone radio reception when making mobile phone to play music, so, the user will have the impression of singing in the KTV as placing oneself in the midst of.
The technical solution of the utility model mainly is: device one signal delay controller, is connected to the radio reception signal processing unit of this signal delay controller on mobile phone, and a broadcast signal processing unit that is connected to this signal delay controller.
The input audio signal system of above-mentioned signal delay controller receives user's sound by microphone, when the signal delay controller receives voice signal from the radio reception signal processing unit, this voice signal can be postponed a period of time, export the broadcast signal processing unit again to, because this broadcast signal processing unit is connected with the handset earphone signal end, therefore, the voice signal after the delay is externally broadcasted by earphone after can mixing with the music signal of the inner broadcast of mobile phone.By this, the user can hear the voice signal that reverberation effect is arranged by earphone, and the impression of singing in the KTV just as placing oneself in the midst of is arranged.
The mobile phone with reverberation function that the utility model provides can make the user when singing with the mobile phone played songs, no longer just faces toward the screen singing, but also has the hearing enjoying of reverberation effect, makes mobile phone really have the effect of singing of Karaoke.
[description of drawings]
Accompanying drawing 2 is the detailed circuit diagram of the utility model Fig. 1.
Accompanying drawing 3 is the schematic appearance with the earphone of the utility model phase configuration.
Among the figure, 10 mobile phones, 11 microphone signal ends, 12 earphone signal ends, 20 signal delay controllers, 21 reset buttons, 22 oscillators, 23 internal memories, 30 radio reception signal processing units, 31 microphone signal amplifiers, 32 low pass filters, 40 broadcast signal processing units, 41 broadcast signal amplifiers, 42 earphone signal amplifiers, 50 earphones, 51 microphones.
[embodiment]
Accompanying drawing 1 is depicted as an a kind of circuit block diagram with reverberation functional mobile phone of the utility model, and it includes:
One signal delay controller 20, export after being used for input audio signal postponed a period of time, this signal delay controller 20 is provided with one and resets end for a reset button 21 connections, connect an oscillator (voltage-controlled oscillator VCO) 22 again, so that clock signal to be provided, wherein this signal delay controller 20 can an external again internal memory (read-only memory) 23;
One radio reception signal processing unit 30, the one end is connected in mobile microphone signal end 11, and the other end is connected with the input of signal delay controller 20; And
One broadcast signal processing unit 40, the one end is connected in handset earphone signal end 12, and the other end is connected with the output of signal delay controller 20.
Circuit in the above-mentioned square can be integrated and be formed in an integrated circuit (U1), as shown in Figure 2; This integrated circuit system is connected with microphone signal end 11 and earphone signal end 12 by peripheral voltage stabilizing circuit.
Please goodbye shown in Figure 1: radio reception signal processing unit 30 be made up of a microphone signal amplifier 31 and a low pass filter 32, and microphone signal amplifier 31 is connected in the microphone signal end 11 of mobile phone by voltage stabilizing circuit.Broadcast signal processing unit 40 is made up of a broadcast signal amplifier 41 and an earphone signal amplifier 42, earphone signal amplifier 42 is connected to the earphone signal end 12 of mobile phone equally by voltage stabilizing and booster circuit, externally broadcasted by earphone 50 with the voice signal that will amplify.
Foregoing circuit system is located at circuit in the mobile phone, and can integrate with mobile phone circuit, and the replacement end of signal delay controller 20 then is controlled by the circuit signal of mobile phone.
More than be a circuit description of the present utility model, circuit operations be described below in conjunction with accompanying drawing 1,3:
Signal delay controller 20 is subjected to the control of mobile phone internal circuit signal and start, has the mobile phone of Kara OK function that is:, and during Kara OK function that the user Activates Phone, the processor of this mobile phone 10 can activate by control signal delay controller 20.At this moment, the user can prepare to have the earphone 50 of microphone 51, insert the earpiece holes of this mobile phone, so, when mobile phone 10 begins to broadcast song under Kara OK function, the user can hear music by earphone, and and then hum, wherein user's sound can be by after microphone 51 radio reception, handle and input to signal delay controller 20 by radio reception signal processing unit 30, this signal delay controller 20 exports broadcast signal processing unit 40 to after the voice signal of radio reception can being postponed a bit of time, because this broadcast signal processing unit 40 is connected to the earphone signal end 12 of mobile phone 10, therefore, the music signal that mobile phone is play can with postpone after voice signal mixes, by earphone 50 broadcasts.Thus, the user can enjoy the effect of reverberation, has the Buddhist of walking back and forth to place oneself in the midst of impression as singing in the KTV.
