Ear-inserting type earphone

Abstract

The invention relates to an ear-in type earphone belonging to the earphone technology field, which comprises an earphone shell, a speaker body disposed in the earphone shell and sound holes disposed in the earphone shell; the earphone shell consists of an earphone front shell and an earphone rear shell; the earphone front shell and the speaker body form an earphone front cavity; the speaker body, the earphone front shell and the earphone rear shell forms an earphone rear cavity. By integrating the earphone front shell and the speaker front cover of the ear-in type earphone, the invention increases the design integration degree of the earphone, simplifies the acoustics design program of the earphone, reduces material and processes for manufacturing the earphone, and saves manufacturing cost; by designing the sound holes into different inner diameter size disposed alternately, the invention effectively improves high frequency effects, and by changing the included angle between the sound hole direction and diaphragm vibration direction to 45-90 degrees, the invention relieves listening fatigue, and achieves an ear-in type earphone with excellent sound quality.

Description

Technical field: [0001] The invention belongs to the technical field of earphones, in particular to an in-ear earphone. Background technique: [0002] Such as figure 1 As shown, the in-ear earphones currently on the market include an earphone housing 102, a speaker body 105 and a speaker diaphragm 107 disposed in the earphone housing 102, and also include a sound output formed by the earphone housing 102 located in front of the speaker body 105 to emit sound. Hole 101, the sound outlet of sound outlet 101 is often made up of a sound outlet through hole of the same diameter, and the sound outlet direction of sound outlet 101 is in the same direction as the vibration direction of horn diaphragm 107; There is a horn front cover 106, an earphone front chamber 103 is formed between the horn front cover 106 and the earphone front shell 102, and a horn front cavity 104 is formed between the horn front cover 106 and the horn body 105, that is, the horn front cover 106 is in contact...

AI Technical Summary

Problems solved by technology

There are many unreasonable factors in such a structural design as follows: the first, the speaker front cover 106 is separated from the earphone front shell 102, which requires the manufacture of two parts, two assembly and testing, and two acoustic performance designs, which just requires Cause the waste of manpower and material resources, increase the manufacturing cost of earphone, and it is difficult to reach the ideal acoustic performance of earphone; The sound waves generated are directly incident on the ear canal of the human ear and reach the tympanic membrane of the human ear, making people feel the sound. When listening to music with this kind of earphone, it is easy to make people feel uncomfortable, especially easy to make people feel fatigued; 3. The sound outlet 101 is composed of a through hole with the same inner diameter. In this design, only one acoustic component and the speaker body form a resonant circuit, and the required high frequency response cannot be further adjusted, so the sound effect is poor.
