Detailed Description

The present invention will be described in detail with reference to fig. 1 to 5.

The utility model relates to a can improve four sound chamber earphones of audio. The utility model discloses an outside casing 1, 1 front end of outside casing is provided with leading sound mouth 11, leads sound mouth 11 and installs into earplug head 2, and 1 inside interior casing 3 that is provided with of outside casing, 3 inside loudspeaker units 4 that are provided with of interior casing, loudspeaker units 4 separate into first sound chamber 5 and second sound chamber 6 with interior casing 3, 5 outsides in first sound chamber are provided with third sound chamber 7, are provided with first through-hole 9 between first sound chamber 5 and the third sound chamber 7, 6 outsides in second sound chamber are provided with fourth sound chamber 8, are provided with second through-hole 10 between second sound chamber 6 and the fourth sound chamber 8. The utility model discloses mainly utilize the sound chamber to the influence principle of earphone audio, outside at first sound chamber 5 sets up third sound chamber 7, 6 outsides at second sound chamber set up fourth sound chamber 8, the earphone is when using, sound is except forming resonance space at first sound chamber 5 and second sound chamber 6, still can get into third sound chamber 7 and fourth sound chamber 8 respectively through first through-hole 9 and second through-hole 10, further filter loudspeaker unit sound, improve the sound purity, increase the low frequency dive simultaneously, make the tuning range wider, the realization is more abundant to the timing of sound, and is accurate. On the other hand, because third sound chamber 7 and fourth sound chamber 8 surround first sound chamber 5 and second sound chamber 6, further isolated outside noise makes the external noise be difficult to get into inside the earphone, and the earphone has better noise reduction effect, can overcome current earphone and only have two sound chambers, difficult, the noise reduction function subalternation problem under the external noise influence of timing to sound.

The utility model discloses in, outside casing 1 is including preceding shell 12, backshell 13 and bottom 14, preceding shell 12 and backshell 13 fixed connection, interior casing 3 sets up in preceding shell 12, bottom 14 joint is in backshell 13.

As shown in the drawings, the front case 12 is provided with a plurality of wire connection holes 15, a wire connector 16 is provided inside the front case 12, an electric wire 17 is connected to the wire connector 16 through the wire connection holes 15, and the wire connector 16 is connected to the horn unit 4. When the music box is used, music signals are transmitted through the electric wire 17 and sent into the internal loudspeaker unit 4 through the wire connector 16 to produce sound.

In the technical scheme, the earphone wire 17 is connected with the wire connector 16 through a contact pin. The pin connection method is more convenient to disconnect and connect than other connection methods.

Referring to fig. 5, the inner housing 3 is open at both ends, and the second sound chamber 6 is composed of the inner housing 3, the speaker unit 4 and the bottom cover 14. The bottom of the second sound cavity 6 can be enclosed by the inner shell 3 or the outer shell 1, in the technical scheme, the inventor utilizes the bottom cover 14 to enclose the bottom of the second sound cavity 6, which is beneficial to saving raw materials.

In the present invention, the speaker unit 4 may be of a moving coil type, an equal magnetic type or an electrostatic type.

In one embodiment, the third sound cavity 7 is provided with a first pressure relief hole 71 communicated with the external atmosphere, and the fourth sound cavity 8 is provided with a second pressure relief hole 81. When not seting up the pressure release hole, totally enclosed front chamber and back chamber make the sound scattering arouse the resonance easily to cause the sound muddy easily, consequently trompil outside the sound chamber usually, help the adjustment to sound, on the other hand, first pressure release hole 71 and second pressure release hole 81 can make the air current business turn over earphone, maintain the pressure stability in sound chamber, avoid the earphone inside to cause the damage because of pressure is too big to user's eardrum etc..

In this technical solution, first pressure relief hole 71 and second pressure relief hole 81 are both disposed in front housing 12. According to actual conditions, second pressure release hole 81 can set up in preceding shell 12, backshell 13 and bottom 14, for saving process flow, improves production efficiency and guarantees the pleasing to the eye degree of earphone, all sets up first pressure release hole 71 and second pressure release hole 81 in preceding shell 12, can once-through processing accomplish.

Preferably, a dust screen 21 is arranged inside the earplug head 2. When the user does not use the earphone for a long time, the dust screen 21 can prevent surrounding dust from entering the inside of the earphone, so that the damage problem of the earphone is avoided.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there may be variations in the embodiments and applications according to the spirit of the present invention, and the content of the description should not be construed as a limitation to the present invention.
