- the thickness of the bottom wall in the sound guiding groove combined with the damping sheet is smaller than the thickness of the bottom wall in other positions in the sound guiding groove.
- a preferred embodiment is that the length of the acoustic conduit is in the range of from 1 mm to 100 mm, and the inner diameter of the acoustic conduit is in the range of from 0.1 mm to 10 mm.
- the present invention has a sound conduit connecting the rear sound chamber and the outside in the earphone, thereby improving the low frequency sound effect of the product; in addition, the sound duct is disposed in the rear sound chamber to reduce the rear sound chamber.
- the volume of the product makes the medium frequency sound effect of the product improved; the newly added sound conduit does not occupy the space of the earphone handle, so that the outer size of the earphone handle can be made small, which is beneficial to ensure a good appearance of the product.
- FIG. 2 is a schematic perspective structural view of an earphone according to an embodiment of the present invention.
- FIG. 4 is a schematic structural view of a headphone casing and an acoustic conduit thereof according to an embodiment of the present invention
- Figure 6 is a cross-sectional view taken along line B-B of the structure shown in Figure 2;
- FIG. 8 is a perspective exploded view of the earphone housing assembly of the second embodiment of the present invention
- FIG. 9 is a cross-sectional view of the earphone housing assembly of the second embodiment of the present invention.
- the outer casing 4 is located on a side of the diaphragm away from the front cover 5, and the rear sound chamber I is formed between the speaker unit 2 and the outer casing 4.
- the speaker unit 2 further comprises a single outer casing for housing the fixed vibration system and the magnetic circuit system. An opening is provided on the back side, so that the airflow on the back side of the diaphragm can communicate with the rear sound chamber I through the opening.
- the earphone provided by the present invention further includes a sound duct 1, as shown in FIG. 3 to FIG. 6, the sound duct 1 in this embodiment has an open end and a curved extension structure, and includes an open end and a closed end, and the open end After the sound chamber I is connected, the closed end closes the other end of the sound conduit 1 through a retaining wall 111. Further, a plurality of through holes 61 are provided in the side wall of the outer casing 4 corresponding to the closed end, and as shown in Figs. 1 to 6, the through holes 61 can communicate the air flow inside and outside the sound conduit 1.
- one end of the sound conduit 1 communicates with the rear acoustic chamber I, and the other end communicates with the outside through the through hole 61.
- the structure in which the airflow in the rear acoustic cavity I communicates with the outside through the tubular acoustic conduit 1 can provide resonance with the sound quality of the speaker unit because the acoustic conduit 1 can provide a larger sound quality than the speaker unit itself, due to The resonance point is lower than the f0 of the speaker unit, so the structure of the sound tube 1 can effectively improve the low frequency effect of the earphone.
- the through hole 61 is located on the bottom wall of the sound guiding groove 110 in the sound conduit 1, as shown in Figs. 3 and 5, that is, the air flow of the rear sound chamber I enters the sound tube 1 and can communicate with the outside through the through hole 61.
- a closing cover 12 is also coupled to the end surface of the opening end of the sound guiding groove 11, and the closing cover 12 is fixedly coupled with the sound guiding groove 11 to form a tubular acoustic tube 1.
- the sealing cover 12 may be a metal material or a plastic material. If the metal material is bonded to the sound guiding groove 11 by bonding, if it is a plastic material, it may be bonded or ultrasonically connected to the sound guiding groove. 11 fixed combination.
- the length of the sound tube 1 is in the range of 1 mm - 100 mm, and the inner diameter is in the range of 0.1 mm - 10 mm, and the sound quality of the sound tube 1 is proportional to the length, and the diameter / the inner diameter.
- the inverse of the squared ratio and the acoustic resistance are sufficiently large that the acoustic impedance of the acoustic conduit 1 is dominated by the sound quality in a sufficiently low frequency band. The resulting low frequency sound is best.
- the thickness d of the position of the bottom wall of the acoustic conduit 1 to which the damping sheet 610 is bonded is smaller than the thickness of other portions of the acoustic conduit 1, as shown in Fig. 5, the bottom wall of the portion
- the structure of the damped sheet 610 after thinning does not reduce the internal space of the sound conduit 1, so that the low frequency effect of the product can be effectively reduced.
- the position corresponding to the rear acoustic cavity I is further provided with the connected acoustic cavity I and The tuning hole 62 of the outside, as shown in FIG. 1 to FIG.
- An acoustic resistance material such as a sponge or a non-woven fabric whose parameters need to match the impedance of the sound conduit 1 and the impedance of the rear acoustic cavity I to adjust the acoustic performance of the intermediate frequency of the earphone.
- the outer casing 4 includes an accommodating portion 41 accommodating the speaker unit 2, and an elongated extending portion 42 integrally extending from one end of the accommodating portion 41, wherein the sound conduit 1 is provided in the accommodating portion 41, and the audio signal line 3 is housed in the extending portion 42.
- the rear acoustic cavity 1 in the first embodiment refers to the space between the accommodating portion 41 and the speaker unit 2.
- the outer casing 4 further includes a fixing portion 7 at the end of the extension tube 42.
- the fixing portion 7 is fixedly coupled with the extension tube 42 to form an earphone handle together with the extension tube 42.

- the fixing of the audio signal line 3 is achieved by the fixing portion 7.
- the extension tube 42 only functions to receive the audio signal line 3, and does not have the structure of the bass reinforcement tube and the external bass reinforcement tube in the conventional structure. Therefore, the size of the extension tube 42 can be set smaller. Moreover, it is not necessary to provide an opening communicating with the outside on the extension pipe 42 or the fixing portion 7, that is, the outer size of the earphone handle can be made small, and thus the structure gives the product a better appearance.
- the inner diameter of the extension tube 42 in this embodiment may be close to the outer diameter of the audio signal line to meet the appearance requirements of the product under specific conditions.
