Abstract

The invention discloses an external playing type earphone. The earphone comprises a loudspeaker arranged in an earphone rear cavity, a first sound hole which is formed in the earphone shell, and a sound guide tube, one end of which is located at a first preset distance in front of the loudspeaker diaphragm, and the other end extends to the first sound hole, and sound generated by the loudspeaker diaphragm in the vibration process is transmitted to the first sound hole through the sound guide tube. According to the invention, through the arrangement of the sound guide tube, sound generated by the vibrating diaphragm of the loudspeaker in the vibration process can be transmitted to the first sound hole through the sound guide tube; and the sound is transmitted to the external environment through the first sound hole, and the equivalent sound quality of the earphone system can be increased through the arrangement of the sound guide tube, so that the resonant frequency of the earphone system is reduced, the low-frequency response under the external playing function is improved, and the sound effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of earphone equipment, and in particular, relate to an externally placed earphone. Background technique [0002] With the development of science and technology, people have more and more demands for earphones. Among them, the external earphones can open both ears, so that users can hear the sound of the surrounding environment while listening to music. It is safer to use and can be used for a long time. Wearing it will not cause discomfort such as ear swelling and ear pressure caused by traditional earphones. In addition, it will not affect the people around you like high-power speakers like speakers. [0003] The system resonance frequency of the speaker unit is Among them, the equivalent sound order of the vibration system of the speaker unit is C as , the equivalent sound quality including the air load is M as . The resonance frequency of the system after the speaker unit is in...
