Description

Technical Field

Background Art

[0002] As an important device for transmitting sound sources, earphone speakers play an important role in playing music and sound. Earphones on the market are generally divided into single-ear earphones and dual-ear earphones based on their structural composition, in-ear earphones and headphones based on their wearing methods, and wired earphones and Bluetooth wireless earphones based on their wired or wireless nature. There are many types of earphones according to different classifications.

[0003] At the same time, current headphones are generally worn in the form of fixed speakers, and the sound effect adjustment mainly relies on the current control of the power amplifier to achieve the purpose of different sound effects such as heavy bass, surround sound, etc.

[0004] For example, the patent document with patent application number CN201720140846.4 discloses a modular headphone design structure that can be combined into a wired headphone or a Bluetooth headphone. Its main structure includes a headphone module, a Bluetooth module and a lead module that are independent of each other. The headphone module includes a speaker module and a headphone plug connected by a lead; the Bluetooth module is provided with a switch, a volume increase and previous song button, a volume decrease and next song button, a lithium battery, a USB charging port and a headphone jack; the lead module includes a headphone plug and a headphone jack connected by a lead, and the headphone plug of the headphone module is matched with the headphone jacks of the Bluetooth module and the lead module.

[0083] The second type: When worn on the head, the head-mounted multi-effect earphone speaker component is used alone.

[0084] Type 3: When worn on the head, the in-ear earphone head structure is worn alone.

[0085] Type 4: When using the in-ear style, wear the in-ear earphone head structure alone.

[0086] The whole of the head-mounted multi-effect earphone speaker assembly can achieve the effect of fixing the thread lock on the rubber adjustment nut 6 by screwing the positioning annular stand 10, and then screwing the rubber adjustment nut 6 to the rubber stud 5 locked on the arc headband 3. After locking, it can also achieve anti-drop positioning in the form of a locking nail. After the head-mounted multi-effect earphone speaker assembly is locked as a whole, the surround earphone head unit 13 can be screwed in and installed by screwing each surround earphone head unit 13 into the central cavity of the negative electrode connecting tube 11 in turn, and then after screwing in, the negative electrode plug-in column 18 exposed by the adjustment notch 12 can be screwed in to adjust the position of the entire surround earphone head unit 13 in the central cavity of the negative electrode connecting tube 11. The distance between each surround earphone head unit 13 and the human ear can be slightly adjusted according to the use of sound effects, so as to achieve the purpose of adjusting the playback effect by arranging the sound source. The adjustment method is diverse and the overall effect that can be achieved is more diverse.
