The so-called high-fidelity of this utility model (High fidelity or Hi-Fi) is the technical term that Fancier uses, the energy perfect reproduction original work sound referred to or the equipment of image and carrier, usually not distortion, there is an accurate response frequency, this noun was widely used to the sixties in the 1950's, DIN chemistry can work out standard in 1973.
Hi-Fi is the abbreviation of English High-Fidelity, literal translates as " high-fidelity ", and its definition is: the playback sound similar to original sound height.
Evaluating a sound system or whether equipment meets high-fidelity requirement, the mode that evaluation of subjective acoustic level and objective indicator test typically should be used to combine is carried out, and with objective examination's index as Main Basis.Because using the performance indications of instrument test equipment, the quantitative result that can compare for reference the most intuitively can be obtained, the most most scientific and trustworthy.
During sound evaluation, according to general term of evaluating, the tonequality of equipment should be carried out overall merit.But evaluation of subjective acoustic level mode unavoidable band point subjectivity is random, it is sometimes prone to the audition attainment by the personnel of participating in evaluation and electing, audition psychology, is accustomed to, likes and the factor such as acoustic surrounding and mode is affected and draws controversial result.The most then should be with objective examination's result for primary evaluation foundation.
The professional person of sound equipment circle is by means of each quasi-instrument, by various means, detect various index to determine the degree of equipment Hi-Fi, Fancier then ear often through oneself goes to judge whether equipment reaches in the eyes of Hi-Fi.Differentiate the height of acoustical reproduction pitch fidelity, not only need equipment and the software of function admirable, but also to have good acoustic surrounding.Therefore, the most correctly weigh the Hi-Fi degree of sound appliances, there is also the difference of objective examination and subjective assessment, but have any to affirm, that is, loyal reduction, reproduce the purest music emotion truly.
The beneficial effects of the utility model can be summarized as follows:
1, sample rate conversion device is that two input blocks shake with twin crystal respectively and do sample rate conversion, one piece of corresponding 44.1k and integral multiple, one piece of corresponding 48k and its integral multiple, and the different audio frequency of input uses different crystal oscillators；Or two input blocks use opa1618 or cs8422 chip to do sample rate conversion respectively, the high-fidelity sample rate conversion of different sample rate audio frequency input can be realized.
2, dual input decoding apparatus uses the decoding of ES9018K2M chip can realize the decoding of dual input high-fidelity respectively.
3, dual input is mixed puts device, and dual input high-fidelity is mixed and put device use in this link and achieve the output of dual input high-fidelity audio mixing.
4, dual-audio player method of the present utility model can the most individually be play accompaniment background audio-frequency or chant audio file, it is non-interfering for accompanying Play System and chanting Play System, also can play after overmulling is put simultaneously, whole method realizes be separately controlled, separately play, or open playing device simultaneously simultaneously.Use the player that device is MP3 or MP4 form of the method, it is possible to be used in the mobile terminal such as flat board, smart mobile phone.
5, player method of the present utility model has multiple play mode: play mode and broadcasting immediately the most immediately adds alarm clock and set time period play mode.Automatic shutdown after n times is play immediately after as selected in double track combination broadcasting content；Or double track combination play content selected after plays automatic stand-by sleep state after n times immediately, and automatic shutdown after playing n times continuously by the time period that alarm clock sets to the time.Additionally, playing device of the present utility model also has sound-recording function, it is stored in and either chants audio frequency or audio accompaniment all can be recorded according to occasion and mental state with oneself.The volume of two tracks can adjust setting numerical monitor respectively, and during use, volume of music is less than reading aloud volume, meets the volume custom of different people；After two track combination broadcasting contents are selected, the re-reading number of times of double track can be set, such as 3 times.
6, this utility model is Promethean, with an one-level amplifying device, the L channel of input audio frequency is amplified respectively, with an one-level amplifying device, the R channel of input audio frequency is amplified respectively, each sound channel is all to amplify respectively, amplifier element plus high-quality, reduce amplifier element number, and make circuit accomplish to optimize design, thus realize mixer and there is the volume of mobile phone size.
7, in this utility model, all amplifying devices are all to amplify respectively to inputting sound channel signal therein, rationally select amplifier element, get rid of the common interference amplified.Signal to noise ratio can reach 100dB, and total harmonic distortion reaches one thousandth.Signal to noise ratio, the distortion factor, frequency response all reach the effect of high-fidelity.
