Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a near-ear type external playback earphone, which comprises: a near-ear type external playback earphone comprises two symmetrical ear hangers 1, a fixed connection structure is formed between the two ear hangers 1 through a data connecting line 2, a first groove cavity 3 and a loudspeaker front cavity 5 are respectively arranged on the outer sides of the ear hangers 1, a controller 4 is arranged inside the first groove cavity 3, a loudspeaker 6 is arranged inside the loudspeaker front cavity 5, a main sound outlet 7 communicated with the loudspeaker front cavity 5 is arranged at one end of each ear hanger 1, an ear hanger cover shell assembly 8 is clamped on the outer side of each ear hanger 1, symmetrical first sliding sleeves 9 are slidably connected with the two outer ends of the data connecting line 2, an integral second sliding sleeve 10 is arranged at the top of each first sliding sleeve 9, an iron wire 11 is slidably connected with the inside of each second sliding sleeve 10, each first sliding sleeve 9 is of a semicircular structure, one end of the bottom of each first sliding sleeve 9 is connected with a magic tape 12, the free end of each magic tape 12 is adhered to the outer side of each first sliding sleeve 9, the outside edge of ear-hang 1 is provided with a plurality of snap columns 13, and speaker 6 is current well-known technology, and its inside vibrating diaphragm that is equipped with, and the outside of first sliding sleeve 9 is provided with the hair side of pasting 12 mutually with the magic subsides.

Referring to fig. 4-5, the ear-hanging cover assembly 8 includes a cover 81, a second recessed cavity 82 and a speaker rear cavity 87 are respectively formed inside the cover 81, a touch switch 83 is disposed inside the speaker rear cavity 87, a plurality of engaging grooves 86 are formed at an inner edge of the cover 81, the engaging posts 13 are in one-to-one correspondence with and are adapted to the engaging grooves 86, a first sound outlet 84 and a second sound outlet 85 communicated with the speaker rear cavity 87 are respectively formed at a bottom of the cover 81, the second recessed cavity 82 corresponds to the first recessed cavity 3, and the speaker rear cavity 87 corresponds to the speaker front cavity 5.

The volume of the front cavity 5 of the loudspeaker is determined according to the working amount of the loudspeaker 6 (too large, spacious and disorderly sound is generated in the body to offset harmonic waves, and too small, sound cannot be released to cause the sound pressure imbalance of the front cavity and the rear cavity).

The forward diaphragm of the loudspeaker and the main sound outlet 7 of the front cavity 5 of the loudspeaker form an inclined plane with an included angle of 30 degrees, so that effective sound pressure is compressed in the cavity and then smoothly released to achieve the original effect (when no included angle exists, for example, when the forward diaphragm and the diaphragm of the loudspeaker are at the same height, released sound can be mutually offset to generate sound field reflection, and as a result, the sound is disordered and cannot enter ears and the like).

The volume of the speaker back cavity 87 is determined according to the working amount of the speaker 6 body, and the principle is that the speaker is designed to restore the sound frequency of 50-20000HZ according to the output of the speaker 6 when the speaker is working (for example, too small can result in the low frequency below 100HZ not being released well, and too large can result in the low frequency below 100HZ not being released well).

The size of the main sound outlet 7 is determined by the volume of the front and back chambers of the speaker and the orientation for optimal hearing to the human ear (e.g., too large will make sound emission less concentrated and less loud, too small will make sound compression emission sharp and without details, and orientation to the ear is very important).

The principle of the first sound outlet 84 on the back is to increase the volume of the rear cavity speaker when the speaker 6 works, the size of the opening is determined by the high sound reproduction, the whole sound reproduction is performed through the density of the sound-transparent net (for example, when the hole is too small, the whole sound is oppressed and suppressed, and the sound is too big, the sound cannot be concentrated, etc.), and the included angle of about 100 degrees is formed between the first sound outlet 84 on the back and the front main sound outlet 7, the sound cannot be generated in the same direction with the main sound outlet 7, the principle is that the frequencies of the sound generated by the first sound outlet 84 on the back and the main sound outlet 7 are different, the speaker of the main sound outlet 7 is released by forward vibration, and the frequency of the sound released by the first sound outlet 84 in the reverse direction is released by the speaker, the same direction interferes with the normal sound reproduction, and cancellation and no disorder can be generated.

The principle of the second sound outlet 85 on the back is that the size of the hollow space is determined according to the size of the hole, the distance from the first sound outlet 84 and the distance from the cavity, so as to release medium and high frequency sound, and achieve the effects of stereo surround and background sound.

The working principle of the utility model is as follows: when using, with the both ends sliding connection of iron wire 11 in the inside of second sliding sleeve 10, then with the both ends of first sliding sleeve 9 sliding connection at data connecting line 2 again, at this moment, can be according to data connecting line 2's length, the interval between two first sliding sleeves 9 of corresponding regulation, treat to adjust the back that finishes, again with the magic paste 12 one end fix in the outside of first sliding sleeve 9 can.

Meanwhile, the user can wrap the data connection wire 2 and the iron wire 11 around the back neck, hang the ear hook 1 on the ear, finally control the touch switch 83, turn on the speaker 6, and play the sound from the main sound outlet 7, the first sound outlet 84 and the second sound outlet 85.

And when not the time spent, open magic subsides 12, can dismantle first sliding sleeve 9, second sliding sleeve 10 and iron wire 11 get off to be convenient for accomodate, next time use install it again can.
