Description
Technical field
The utility model relates to a kind of loudspeaker, particularly a kind ofly can read multiple different music information form, the loudspeaker that have mobile playing function simultaneously.
Background technology
The main application of loudspeaker is a sounding, and what therefore claim again is loudspeaker.Please refer to shown in Figure 1ly, is the synoptic diagram of typical loudspeaker 10.Audio amplifier 12 promptly is the shell of loudspeaker 10, and its purpose is to allow complete forwards the dispersing of sound wave, disturbs to avoid producing toward the sound wave of other directional divergence the normal sounding of loudspeaker 10 being produced.Has at least one monomer 14 in audio amplifier 12 inside to produce sound wave.Owing to different monomers 14 suitable range scopes have nothing in common with each other, therefore, the voice signal A of extraneous input must divide into the sound road of height different frequency via frequency divider 16, imports suitable monomer 14 respectively truly to present sound.
It should be noted that in order to drive monomer, after each sound road signal must amplify through amplifier earlier, just import in the monomer.And, can divide into active loudspeaker and passive type loudspeaker according to having amplifier in whether in the loudspeaker.The loudspeaker that have amplifier promptly are active loudspeaker, and not built-in amplifier person is called the passive type loudspeaker.Generally speaking, amplifier must feed power supply and can carry out this amplification effect.Therefore, traditional active loudspeaker are device one attaching plug usually, to feed required power supply.
Because active loudspeaker must can be worked in plug-in, therefore, can't provide the demand of mobile playback.Again, though the passive type loudspeaker need not feed power supply,, the voice signal of input passive type loudspeaker amplifies through amplifier in fact.And amplifier is in the process of carrying out the voice emplifying signal, must plug-in to obtain the power supply supply.By above-mentioned, no matter be active loudspeaker or passive type loudspeaker as seen, all must obtain the required power supply of voice emplifying signal by supply socket.
In addition, please refer to Fig. 1, the voice signal S of input loudspeaker 10 only handles through frequency division, promptly drives each monomer 14 to produce sound wave.In other words, the voice files form of generally commonly using, for example: the track data of MP3, WMA, WAV and CD, and cannot directly import loudspeaker to drive each monomer generation sound wave.And must be through the conversion of decoding and digital-to-analog, behind the voice signal A of generation one simulation, just imported loudspeaker.Generally speaking, the switching motion of above-mentioned decoding and digital-to-analog is to carry out in the sound card of computing machine or in the CD player.Therefore, the user is if there is the demand of mobile playback, except loudspeaker, also must carry computing machine or the CD player just can reach the purpose of playback, and the user is produced sizable load.
It should be noted that the aforementioned voice files form of playing by the CD player only limits to be made in the data content on the discs.Therefore, if the user has the File Format of other pattern, for example: be stored in the interior voice files of displacement disc, be stored in the interior voice files of storage card etc., must through computing machine these archives be made on the discs earlier, could play back by the CD player.Otherwise, can only just can reach the purpose of playback by computing machine.
As described above, can find that face the demand of mobile playback, traditional horn designs has following shortcoming:
One, traditional horn designs must provide amplifier required power supply by plug-in, can the voice emplifying signal, reach the purpose of playback.Therefore, if can't find supply socket, these loudspeaker also just can't operate as normal.
Two, traditional loudspeaker can't be supported the File Format that widely uses now, and can only support analoging sound signal.Therefore, the user plays these voice files forms as if desire, has only to use a computer or suitable CD Player, these voice files format conversion could be become voice signal input loudspeaker to produce sound.
