Description
Technical field
The utility model is related to a kind of Headphone structure, the structure of the new adjustment bass frequencies of more particularly to a kind of earphone.
Background technology
The earmuff of general headphone, earmuff internal diameter is more than phonation unit external diameter, and in phonation unit front shroud and
The structure (as shown in Figure 1) of air-flow drainage pressure, therefore the earmuff when people take earphone in earphone are not provided with earmuff
Stream pressure is just generated with phonation unit front shroud, the anterior pressure of phonation unit when making to put on is inconsistent with back, causes
The sound film deformation of phonation unit, so as to produce noise, the unhappy sensation of hearing is caused to user.
Utility model content
The purpose of this utility model is the stream pressure adjustment structure for providing a kind of earphone, can effectively drain air-flow pressure
Power, prevents the deformation of phonation unit sound film from occurring noise.
The utility model is achieved through the following technical solutions：
The utility model provides a kind of stream pressure adjustment structure of earphone, and the earphone is included before earmuff, phonation unit
Phonation unit film is provided with shell and phonation unit after cover plate, earphone, the phonation unit, the earmuff is placed on the sounding
On unit front shroud, and formed with the phonation unit front shroud after front chamber, the phonation unit front shroud and the earphone
Shell is fixed together, and the phonation unit is fixed on the phonation unit front shroud, is placed in the rear shell of shell after the earphone
In chamber, sender, venthole and the position of bone are provided with the phonation unit front shroud, the position of bone is located at the venthole
By side.
Further, the earmuff internal diameter is equal with phonation unit external diameter or less than phonation unit external diameter.
Further, the position of bone is arranged at the venthole one or both sides.
Further, angle of inclination is set on the position of bone.
The beneficial effects of the utility model are：
The stream pressure adjustment structure that the utility model provides a kind of earphone can effectively drain stream pressure, prevent hair
Noise occurs for the deformation of sound single vowel film, improves the hearing effect of earphone.

Embodiment
Embodiment of the present utility model is specifically illustrated below in conjunction with the accompanying drawings, and accompanying drawing is only for reference and explanation is used, not structure
The limitation of paired the utility model scope of patent protection.
Embodiment 1：
As shown in Fig. 2 the utility model provides a kind of stream pressure adjustment structure of earphone, the earphone include earmuff 1,
Shell 3 and phonation unit 4 after phonation unit front shroud 2, earphone, the internal diameter of earmuff 1 are equal with phonation unit external diameter or less than hair
Phonation unit film 401 is provided with the external diameter of sound unit 4, the phonation unit 4, the earmuff 1 is placed on before the phonation unit
On cover plate 2, and formed with the phonation unit front shroud 2 after front chamber 101, the phonation unit front shroud 2 and the earphone
Shell 3 is fixed together, and the phonation unit 4 is fixed on the phonation unit front shroud 2, is placed in shell 3 after the earphone
Afterwards in shell chamber 301, sender 201, venthole 203 and the position of bone 202, the bone are provided with the phonation unit front shroud 2
Position 202 is located at the side of the venthole 203.
In the present embodiment, angle of inclination 204 is set on the position of bone 202.
Embodiment 2：
As shown in figure 3, the present embodiment difference from Example 1 is：The position of bone 202 is arranged at the venthole
203 both sides.
As Figure 4-Figure 6, the one or both sides of the utility model venthole 203 on phonation unit front shroud 2 are set
The position of bone 202 so that even if covering venthole 203 by earmuff during wearing, can also discharge stream pressure to shell chamber after earphone
Ante-chamber 101 is set to turn into air-tight state after 301, and wearing, while also according to the shape of earmuff 1, setting and tilting on the position of bone 202
Angle 204, alteration of form when being worn because of earmuff, earmuff is attached to the angle of inclination on the structure of the position of bone and the position of bone 202, makes
Stream pressure is more easy to be discharged to shell chamber 301 after earphone by venthole, and eliminating the stream pressure occurred when wearing prevents sounding list
First 4 sound films deformation, it is to avoid produce noise, as shown in fig. 6, venthole is plugged when human ear 5 puts on earphone, turn into ante-chamber
Air-tight state, have adjusted the sound of phonation unit low frequency.
Above disclosed is only preferred embodiment of the present utility model, it is impossible to right of the present utility model is limited with this
Protection domain, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the model that the utility model is covered
Enclose.
