Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an open earphone which is convenient for receiving sound. Background Art

[0002] Open-back headphones are a popular type of headphones. The characteristic of this type of headphones is that they use sponge-like microporous foam plastic to make sound-permeable ear pads. They are small in size and very comfortable to wear, and no longer use heavy sound-stained pads. As a result, there is no sense of isolation from the outside world, and the sound can leak out, and vice versa, the sound of the outside world can also be heard. If the degree of openness of the headphones is very high, the sound from the unit on the other side can be heard, forming a certain mutual feedback, making the listening experience natural.

[0003] Open-type headphones usually have a microphone and an air vent (tuning hole), where the microphone is used to receive sound and the air vent is used to ensure sound quality. In order to set up the microphone, some open-type headphones on the market are equipped with a stem, and a microphone is set on the stem. This design will increase the size of the open-type headphones, making them inconvenient to store. At the same time, the structure of this type of headset is too complicated and the cost is high. In addition, open-type headphones usually have a pressure relief hole on the headphone shell. When the headphones are working, gas flows at the position of the pressure relief hole. If the pressure relief hole set in the shell is close to the microphone, it may affect the microphone on the headphone shell.

[0004] For example, the open-type earphone disclosed in application number: CN202122259182.2 has a rod-shaped microphone rotatably disposed on the outside of the earphone body, and a microphone sound receiving port is disposed at the end of the rod-shaped microphone. The rod-shaped microphone is rotated around a rotating shaft to adjust the alignment direction of the microphone sound receiving port. The rod-shaped microphone is rotatably connected to the earphone body through a conventional rotating shaft. It can be seen that the structure of the external rod-shaped microphone of this type of open-type earphone is relatively complex and is not conducive to storage.

[0005] For example, a low-latency open-type Bluetooth headset and an external microphone rod disclosed in application number: CN202222882020.9 also have the problem of a relatively complex structure, which is not conducive to storage.

[0006] For example, an open-type earphone disclosed in application number: CN202322171454.2 specifically discloses that a sound outlet hole is provided on the inner side of the shell facing the user's auricle, which is used to guide the sound generated by the front side of the diaphragm out of the shell and then transmit it to the ear canal, and at least two pressure relief holes are provided on the other side walls of the shell. If the pressure relief hole is close to the microphone, it may affect the integrated microphone. Utility Model Content

[0007] In view of this, the present invention aims to overcome the deficiencies of the prior art, and its main purpose is to provide an open-type earphone that is easy to receive sound. The earphone not only adopts an integrated earphone for easy storage, but also the pressure relief hole is far away from the microphone, and the microphone will not be disturbed by the pressure relief hole, thereby overcoming the deficiencies of the prior art.
