Description

Technical Field

[0001] The utility model relates to the field of earphones, in particular to an earphone air relief groove structure. Background Art

[0002] Headphones are a common audio device in our daily lives, helping us better enjoy music, videos, and other multimedia content. Sound quality directly impacts the quality of a pair of headphones. High-quality headphones typically utilize advanced driver units and sound isolation technology to reproduce more accurate and detailed audio details. They also offer a wider frequency response, allowing listeners to experience richer musical elements, including a balanced bass, midrange, and treble.

[0003] Usually, the production of any sound requires certain conditions, and the sound-producing principle of headphones is that a small speaker is placed in the headphones, and the cone of the headphones and the electromagnet produce a vibration reaction, and then the sound waves are transmitted to the air to form sound. At the same time, the vibration of the cone and the electromagnet of the headphones will also increase the internal pressure of the headphones. In addition, the headphones are originally in a closed and narrow state, so it will also hinder the sound of the speaker; the cavity structure of the headphones is a completely closed design except for the sound outlet, so when the diaphragm of the headphone speaker vibrates back and forth, the sound waves radiated to the surroundings are all released in this direction except for the sound outlet, and the sound wave energy in other directions is wasted, especially the low-frequency sound waves. Adding vent holes in the front and back cavities of the earphones can release sound waves from other places; however, if all the vent holes are open, there will be more than one outlet for the sound waves, and the sound will become muddy, so an vent net is needed. Without the vent net, the sound will be completely muddy; if all the vent holes are blocked, the sound will instantly become very fresh, without any low frequency. In other words, the vent holes change the direction of the sound, and the tuning net changes the air pressure in the cavity; in this way, the small holes on the earphones were applied. In order to allow the air in the front and back cavities of the earphones to flow in and out freely, produce a good vibration effect, and reduce the pressure inside the earphones, the front and back cavities vent holes are designed for ventilation. The sound quality produced in this way is better, and the earphones will naturally bring people a better spiritual experience, so these small holes are also called tuning holes.

[0004] The position of the existing vent holes is not fixed. The structure of each earphone is different, so the position of the hole will be different. When the vent holes are blocked, the airflow in the earphone cavity cannot circulate or leak out, which will directly damage the sound quality of the earphone, and even cause serious damage to the earphone. At the same time, Bluetooth earphones such as TWS and OWS are generally small in size, and have PCBA, battery and other components inside. It will be difficult to find a suitable vent hole position on the shell surface. In addition, the so-called "one thousand ears for one thousand people", everyone's ear contour has deviations, and when wearing, the hole is prone to blockage, which seriously affects the user's subjective experience, poor usability, and a small scope of application.

[0008] As a preferred solution, the air relief groove is a circular groove, and the diameter of the air relief groove is 1.6 mm.

[0009] As a preferred solution, the diameter of the air leakage hole is 0.8 mm.

[0010] As a preferred solution, the air relief groove and the air guide groove have the same depth.

[0011] As a preferred solution, the depths of the air relief groove and the air guide groove are both 0.5 mm.
