As shown in fig. 1 to 6, the earphone comprises an earmuff 1, wherein an accommodating space 2 with an opening is arranged on one side of the earmuff 1, and a sound production unit 3 is arranged on the side wall at the front end of the accommodating space 2.

In this embodiment, ear muff 1 is in the use, and accommodation space 2 covers and establishes on auricle 4, and sound generating unit 3 is located accommodation space 2's front end, and based on auricle 4 and sound generating unit 4's positional relationship, sound that sound generating unit 3 sent can first transmit to auricle 4 on, in the sound canal is transmitted again after auricle 4 handles. The earphone with the structure has the advantages that the sound received by the human ear conforms to the habit of receiving the sound normally by the human ear, the sound received by the human ear is more real, the problem that the sound sent by the existing earphone can cross the auricle 4 and is directly transmitted to the auditory canal is solved, the processing process of the auricle 4 to the sound is reduced, and the problem that the sound received by the human can be distorted is solved.

Referring to fig. 5 and 6, the sound emission unit 3 includes a main sound emission unit 31 and an auxiliary sound emission unit 32. Different sounds are emitted by different sound emitting units through the arrangement of the main sound emitting unit 31 and the auxiliary sound emitting unit 32. The real listening environment of human ears can be simulated, so that the sound heard by the human ears is more real. For example, the sound emitted from the main sound emission unit 31 is a speech sound, and the sound emitted from the auxiliary sound emission unit 32 is an environmental sound.

Furthermore, the accommodating space 2 is provided with a sound generating unit at other positions except the front end, for example, the rear end, the upper end and the lower end of the accommodating space 2 are provided with sound generating units. Through the arrangement of the plurality of sound production units, the sound effect heard by human ears can be more three-dimensional.

In addition, the front end, the rear end, the upper end and the lower end specifically mean that, in the use process of the earphone, one end of the earmuff 1 close to the face is the front end, the end opposite to the front end is the rear end, the upper end is the end of the earmuff 1 close to the top of the head, and the end opposite to the upper end is the rear end.

Referring to fig. 1 and 2, the earmuff 1 comprises a shell 11 and a spongy cushion 12, wherein the shell 11 is provided with a groove, the spongy cushion 12 is of an annular structure, and the spongy cushion 12 is arranged at the opening of the groove.

The recess of the housing 11 and the annular space of the sponge mat 12 constitute a containing space, and the sound generating unit 3 is provided on the housing 11.

The foam-rubber cushion 12 is detachably connected with the shell 11, and the earmuff 1 comprises a plurality of foam-rubber cushions 12 of different types. Because there is the difference in the size of people's ear, through the foam-rubber cushion 12 who sets up a plurality of different models to and foam-rubber cushion 12 can be dismantled with shell 11 and be connected, to different people's ear sizes, can change different foam-rubber cushion 12, promptly, can realize adjusting accommodation space 2's size through setting up different foam-rubber cushion 12.

The receiving space 2 is covered outside the auricle 4, and a distance exists between the side wall of the receiving space 2 and the edge of the auricle 4. Through this kind of setting, can make auricle 4 avoid the oppression of ear muff 1, can make auricle 4 completely stretch out be located accommodation space 2, from this, can make auricle 4 be in normal radio reception state, avoid because of the radio reception distortion that auricle 4 pressurized deformation leads to. For different sizes of human ears, the sponge pad 12 can be replaced to ensure that a space exists between the accommodating space 2 and the auricle 4.

The general dimensions of the pinna 4 are: the length is 5-8cm, the width is 3-4cm, and the thickness is 1.5-2.5 cm. Therefore, the length of the accommodating space 2 is 6-9cm, the width is 4-5cm, and the depth is 2-4 cm. The shape of the accommodating space 2 may be set according to actual conditions, and the size of the accommodating space 2 refers to the minimum size in the longitudinal direction, the width direction and the depth direction, and the accommodating space may be appropriately deformed in the above respective directions, but cannot be smaller than the above size range.

The angle alpha between the midline of the sound generating unit 3 and the plane of the opening of the accommodating space 2 is 25-40 degrees. Preferably, α is 30 °. By the arrangement of the sound generating unit 3, the normal listening mode of human ears can be simulated, and the sound generated by the sound generating unit 3 can directly act on the auricle 4.

The earphone comprises two earmuffs 1, the two earmuffs are a left earmuff and a right earmuff respectively, and the left earmuff and the right earmuff are connected through a connecting beam 5.

Specifically, tie-beam 5 is extending structure, and through making connecting-beam 5 extending structure, in the use of earphone, the position of ear muff about adjustment that can be convenient, so, can make 2 covers that accommodation space can be better establish in auricle 4 outsidely, can make and have the interval between auricle 4 and the 2 lateral walls of accommodation space.

The left earmuff and the right earmuff are connected through a sound guide structure. When the human ear receives sound, the two ears can receive the sound emitted by the same generating source. Through the setting of leading sound structure, can make partial sound conduct between left and right earmuffs. The normal listening habit of the human ear can be simulated, so that the sound received by the human ear is more real.

Referring to fig. 2, in the present embodiment, a specific structure of the sound guide structure is provided, the sound guide structure is a sound guide tube 6, one end of the sound guide tube 6 is communicated with the accommodating space 2 of the left earmuff, and the other end of the sound guide tube 6 is communicated with the accommodating space 2 of the right earmuff. The connection point of the sound-guiding tube 6 to the muff 1 is located at the rear end of the receiving space 2.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
