The semi-in-ear earphone bass tube device has the advantages that the bass tube which is arranged in a snake-shaped bending mode is arranged in the rear cavity, so that sound pressure behind the earphone loudspeaker can be emitted only through the section of tube, the purpose of attenuating high frequency with short wavelength is achieved, low frequency sound with long wavelength cannot be influenced and cannot generate resonance, and frequency resonance is generated only in a low frequency range such as 100-300Hz, so that the effect of enhancing bass is achieved.
Description
Technical Field
The utility model relates to an earphone technical field, concretely relates to half in-ear earphone bass tube device and earphone.
Background
Along with the development of TWS bluetooth headset, half in-ear earphone does not have the ear pressure after wearing because there is the leakage between with the earphone, and is more comfortable, promotes the music and enjoys the experience. Therefore, the existing bluetooth half-in-ear earphone is more and more favored by consumers, but the low frequency of the earphone generally has the phenomenon of low frequency deficiency due to leakage, and the conventional method uses a DSP to improve the deficiency of the low frequency band, but the tone quality of the method is generally not real enough, and the hearing feeling is still not ideal.
Disclosure of Invention
In order to overcome the shortcoming and the inadequacy that exist among the prior art, the utility model aims to provide a half in-ear earphone bass pipe device, through adopting the bass pipe that sets up snakelike bending setting in the rear chamber, let the latter acoustic pressure of earphone loudspeaker can only send out after this section pipe, reach the purpose of the short high frequency of decay wavelength, and then can not influence to the longer low frequency sound of wavelength, but directly go straight out through the bass pipe, can not produce resonance, only produce frequency resonance if 100 supplyes one's of frequencies in the low frequency section of specially low frequency, thereby get up the effect of bass reinforcing.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a half pleasant formula earphone bass pipe device, includes the sealed shell that sets up and sets up the loudspeaker in the shell, loudspeaker cut off the inside cavity of shell for antechamber and back chamber, the front portion of shell sets up out the sound passageway, goes out the sound passageway and is connected with the earcap with antechamber intercommunication and the outer end of going out the sound passageway, the shell extends and is provided with handheld portion, place the bass pipe that snakelike bending set up in the handheld portion, the sound inlet of bass pipe with back chamber intercommunication, the play sound end and the external environment intercommunication of bass pipe.
The junction of handheld portion and shell is provided with the barricade, and the barricade cuts off the inner space of back chamber and handheld portion, and the barricade has been seted up and has been led the sound hole, handheld portion has been seted up with the tip that the barricade opposite direction and has been gone out the sound hole, the sound inlet and the sound hole intercommunication of leading of bass pipe, the play sound end of bass pipe with go out the sound hole intercommunication.
The bass tube is a plastic tube or a metal tube.
An earphone as described above, comprising a semi-in-ear earphone bass tube apparatus as described above.
The shell comprises a middle shell, a front shell connected with the middle shell and a rear cover used for covering the middle shell and the handheld part.
The sound outlet channel is positioned in the front shell, the front end of the loudspeaker is positioned in the front shell, and the rear end of the loudspeaker is positioned in the middle shell.
The rear of loudspeaker is provided with the battery, and the rear of battery is provided with the PCB board, and loudspeaker and PCB board electric connection, battery and PCB board electric connection.
The PCB is provided with an MIC device.
The beneficial effects of the utility model reside in that: the utility model discloses a half in-ear earphone bass tube device sets up the bass tube that snakelike bending set up in the back chamber through adopting, the bass tube diameter is less, length is longer again simultaneously, let the acoustic pressure behind the earphone loudspeaker can only send out after this section pipe, after the multiple reflection, reach the purpose of the short high frequency of decay wavelength, but can not influence the long low frequency sound of wavelength, but directly go straight out through the bass tube, can not produce resonance, only produce the frequency resonance such as 100 thin walled carbon fibers 300Hz in the low frequency section very much, thereby get up the effect that the bass is strengthened, the conventional way in the market can use DSP to promote the not enough of low frequency section, but this kind of tone quality is generally unreal, it is still not ideal in the sense of hearing now, adopt a method that increases a bass tube in the back chamber of earphone to produce a resonance in the low frequency section, thereby promote the low frequency, the hearing feeling is more natural, and the cost is lower.
The utility model discloses an earphone produces a resonance at the low frequency range to promote the low frequency, can be more natural in the sense of hearing, the cost can be lower.
