Abstract

The utility model discloses an earphone external passive frequency dividing and sound device which comprises a passive external frequency dividing circuit and a passive sound module. An audio signal is firstly input to the passive sound module for processing, then is input to the passive external frequency dividing circuit for frequency dividing, and is finally input to a loudspeaker unit. The audio signal comprises left and right channels. The input right channel signal is processed by the passive sound module and then is combined with the left channel. The left channel is processed by the passive sound module and then is combined with the right channel. By adopting the above scheme, a consumer can freely replace an earphone. Other companies can meet the needs of different consumers by designing the internal circuit scheme provided by the utility model, so that consumers can acquire unprecedented independent sound combination right. According to another key point, a special microphone for conversation or recording can be built in the product; when the product is connected with a mobile phone, the product can be used for hands-free conversation; and music and conversation can be freely switched.

Description

The external passive type frequency division of earphone and audio apparatus
Technical field
The utility model relates to the passive type frequency divider of earphone, and what more specifically relate to is the external passive type frequency division of earphone and audio device circuit.
Background technology
Present earphone product if only use 1 phonation unit, generally can not add any passive or active partial or sound effect circuit in earphone.This has caused the tonequality of earphone can not see through more effective mode and has regulated, and can only adopt ready-made earphone horn scheme, limited to the tone color performance of 1 unit earphone product greatly, also caused market to be specified the unit of high-end loudspeaker producer to monopolize by some, strength is not enough to purchase the company of this class unit, and product can only be in the low side migration.
If use the earphone product of 2 or above unit, the frequency divider of good design just becomes the soul of whole proposal, yet under the actual conditions, consider the volume restrictions of earphone external form, engineers all can only be simplified frequency dividing circuit design wherein as far as possible, this has caused too simple frequency divider design, thereby order is seriously limited to the performance of each road loudspeaker monomer, and the increase of the volume of earphone external form and partial and sound effect circuit is a contradiction, basic problem could not solve if therefore can only be built in interlock circuit in the ear casing!
Another major issue is, earphone product part belongs to the product of physical acoustics, therefore the shell of earphone is so that the internal cavity structure, great to final sound influence, therefore traditional tuning mode (as using damping material or changing cavity geometry) could not provide more cavity space substantially, carries out the design of passive type circuit!
The utility model content
At the deficiencies in the prior art, the utility model is outwards drawn general required built-in frequency division and the sound effect circuit of earphone, after connecting the earphone that cooperates, can perfection address the above problem.
To achieve these goals, the utility model is by the following technical solutions:
The external passive type frequency division of earphone and audio apparatus, it is characterized in that: comprise a passive external frequency dividing circuit, one passive type audio module, audio signal at first input to and input to passive external frequency dividing circuit again after the passive type audio resume module and carry out transporting to loudspeaker unit behind the frequency division.
Described audio signal is L channel and R channel, and passive type audio module is attached to L channel after the right-channel signals of input is handled, and L channel is attached to R channel after passive type audio resume module.
Described loudspeaker unit is high pitch, middle pitch, bass output.
Consumer behind the employing such scheme could freely change earphone, and other companies also can see through design the utility model internal circuit scheme, satisfy different consumers' needs, match power thereby make consumers in general obtain unprecedented autonomous audio! Another emphasis is that this product can built-in conversation or the special-purpose miaow head of recording, when connecting mobile phone, can be used as hand-free call and use, and listens the song conversation freely to switch.When using on special recorder, except playback, can also radio reception!
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model embodiment one,
Fig. 2 is the circuit theory diagrams of the utility model embodiment two.
Specific implementation method
According to accompanying drawing utility model is described in further detail below:
The external passive type frequency division of earphone as shown in Figure 1 and audio apparatus, comprise a passive external frequency dividing circuit, one passive type audio module, audio signal at first input to and input to passive external frequency dividing circuit again after the passive type audio resume module and carry out transporting to loudspeaker unit behind the frequency division.An audio signal of narrowing head input is divided into and is L channel and R channel, and passive type audio module is attached to L channel after the right-channel signals of input is handled, and L channel is attached to R channel after passive type audio resume module.The hearing effect of true environment be can simulate, high pitch, middle pitch, bass output divided via loudspeaker unit again.
The external passive type frequency division of earphone as shown in Figure 2 and audio apparatus, comprise passive external frequency dividing circuit, one passive type audio module, audio signal at first input to and input to passive external frequency dividing circuit again after the passive type audio resume module and carry out transporting to loudspeaker unit behind the frequency division.The audio signal of narrowing the head input is L channel and R channel, and passive type audio module is attached to L channel after the right-channel signals of input is handled, and L channel is attached to R channel after passive type audio resume module.The hearing effect of true environment be can simulate, high pitch, middle pitch, bass output divided via loudspeaker unit again.When connecting mobile phone, can be used as hand-free call and use, listen the song conversation freely to switch.When using on special recorder, except playback, can also radio reception.
The above embodiments limit content of the present utility model just for better explanation the utility model, rather than with this, thus all trickle change and equivalent variations of under the spirit of this patent, making, all in the protection range of this patent.
