Abstract
The utility model discloses a variable equalizer for portable consumer electronics. The variable equalizer comprises an audio power amplifier module, an audio low frequency reserving module, an audio response curve simulation module and a soft equalizer. The audio power amplifier module, the audio low frequency reversing module and the audio response curve simulation module are connected with the soft equalizer synchronously. The variable equalizer of this utility model has a simple and reasonable structure. Audio power is amplified by the audio power amplifier module, and the low frequency part of audio is reserved by the audio low frequency reserving module. The frequency of sound is adjusted by the soft equalizer; when the volume is low, sound of low frequency is reserved without attenuation; as the volume is turned up, the low frequency part is attenuated gradually to match the audio response curve of loudspeakers so as to obtain great sound quality and bigger volume; thus the requirements of different electronic products on sound can be met by the same set of audio equipment.
Description
Technical field
The utility model belongs to the audio tunning equipment technical field, specifically relates to a kind of variable equalizer that is used for portable consumption electronic product.
Background technology
Present portable consumption electronic product, for example mobile phone, MP3, MP4 etc., raising along with scientific and technological level and electronics industry level, the volume of these portable consumption electronic products is more and more littler, what cause that the sound chamber of electronic product and loudspeaker can not do is very big, and what this brought undoubtedly thereupon is music or acoustic reduction.And present people expect to require the outer playback amount of sound of these electronic products increasing, tonequality is become better and better.
Generally, the loudspeaker of these electronic products are better to the high pitch partial response, and are relatively poor to the bass part response.And can find the research of sound, when the sound of the big volume of needs, then need to increase the high pitch part, when improving tonequality, needs then need to increase bass part, and at different electronic products, need design different audio frequency apparatuses according to the products characteristics of electronic product self to satisfy the demand of people's sound, this will expend design time and the expense of enterprise to electronic product, must adjust accordingly production line simultaneously, certainly will reduce the benefit of enterprise; And can't satisfy the demand of different electronic products to big volume and high tone quality to same set of audio frequency apparatus.How solution adopts same set of audio frequency apparatus to adapt to different electronic products becomes the problem that presses for solution at present to the demand of sound.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple and reasonable, realizes that same set of audio frequency apparatus adapts to the variable equalizer that be used for portable consumption electronic product of different electronic products to the sound demand.
The technical problem that the utility model proposed is to solve like this: a kind of variable equalizer that is used for portable consumption electronic product, described variable equalizer comprises: an audio frequency multiplying power power amplifier amplification module, described audio frequency multiplying power power amplifier amplification module is in order to heighten the audio frequency multiplying power, and an audio frequency low frequency keeps module, described audio frequency low frequency keeps module in order to keep the signal of audio frequency low frequency part, an and acoustic frequency response curve simulation module, described acoustic frequency response curve simulation module is in order to corresponding the carry out curve simulation of loudspeaker to audio signal, an and soft equalizer, described soft equalizer carries out equilibrium adjustment, described audio frequency multiplying power power amplifier amplification module to audio signal, the audio frequency low frequency keeps module, acoustic frequency response curve simulation module is connected with soft equalizer simultaneously.Described variable equalizer also comprises the source of sound input module that receives the source of sound input.Described variable equalizer also comprises the audio frequency output module to audio frequency of broad band power amplifier output audio signal, after audio signal after tuning outputs to widescreen band audio frequency power amplifier by this audio frequency output module, play out sound by the loudspeaker that are connected with this widescreen band audio frequency merit.
The utility model is simple and reasonable, by variable equalizer of the present utility model the audio frequency multiplying power is heightened by audio frequency multiplying power power amplifier amplification module, is kept by the low frequency part of audio frequency low frequency reservation module with audio frequency.The low-and high-frequency amount of regulating sound by soft equalizer, when volume hour, low-frequency sound is not done decay; Along with volume increases, low frequency part is slackened gradually, with the acoustic frequency response curve of cooperation loudspeaker, and then obtains good sound quality and bigger volume; Realized that same set of audio frequency apparatus adapts to the demand of different electronic products to sound.
