Structure schematic diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein
Described specific embodiment is used only for explanation the utility model, rather than to restriction of the present utility model.Further need exist for
It is bright, for the ease of description, part rather than the entire infrastructure related to the utility model is illustrate only in accompanying drawing.
Fig. 1 is a kind of knot for producing the Portable earphone audio devices of theater effect in the utility model embodiment
Structure schematic diagram, as shown in figure 1, for produce theater effect Portable earphone audio devices include L channel attenuation units 21,
R channel attenuation units 22, L channel delay unit 23, R channel delay unit 24, L channel reverberation unit 25 and R channel are mixed
Ring unit 26.
Wherein, L channel attenuation units 21 and R channel attenuation units 22, for respectively from the L channel in audio signal
Separate section signal carries out attenuation processing in signal and right-channel signals, forms L channel deamplification and R channel decay letter
Number.L channel delay unit 23 and R channel delay unit 24, respectively with L channel attenuation units 21 and R channel attenuation units
24 are connected, for carrying out delay process to L channel deamplification and R channel deamplification, to reach left and right ear reception
Sound between time lag, so as to sense of direction of the user for sound source can be aroused.L channel reverberation unit 25 and R channel
Delay unit 24 is connected with audio input interface 10, the left channel signals for obtaining R channel deamplification and input, carries out
Reverberation is processed.R channel reverberation unit 26, is connected with L channel delay unit 23 and audio input interface 10, for obtaining left sound
Road deamplification and the right-channel signals of input, carry out reverberation treatment.Reverberation treatment can eliminate sense of the loudspeaker as point source
Feel, user is experienced the sound from multiple directions, and third dimension and Sensurround can be increased, so that user has more
Profound hearing enjoying.
It should be noted that L channel attenuation units 21 and R channel attenuation units 22 are additionally operable to in separate section signal
The signal of setpoint frequency point carries out amplification treatment.That is, L channel unit not only can be to the part of the separation from left channel signals
