The second end face 22 comprises, in the region of the proximal ear-hook portion, a projection 22a extending vertically upwards, which projection 22a is fixedly connected or integrally formed with the second end face 22 and has the shape of a substantially hollow cylinder. The projection 22a is rotatably formed in a through-hole in the connecting section 9. The first end face second half 122 comprises perforations corresponding in size and position to said protrusions 22a, the rotation pin 12a being able to be inserted simultaneously into the perforations of the first end face second half 122 and into the protrusions 22a, so as to connect the device housing rotatably about the axis x with respect to the connection section 9.
Within the device housing a number of functional elements for the earphone device, such as an earphone driver 3, a battery 10, a printed circuit board, etc., are arranged. In which the earphone driver 3 is arranged in the region of the far ear-hook between the first housing half 1 and the second housing half 2, respectively constituting a rear chamber between the first housing half 1 and the earphone driver 3 and a front chamber between the second housing half 2 and the earphone driver 3. In the state that the earphone is worn, the front chamber faces the ear of the user, and the rear chamber faces away from the ear of the user. The volume of the front chamber is 291mm 3; the volume of the rear chamber is 896mm 3.
To improve the low frequency effect, it is necessary to provide good ventilation performance for the rear chamber. For this purpose, a front vent 6 is provided in the region of the second end face 22 of the second housing half 2, which is remote from the ear-hook, and also serves as a sound outlet for the secondary device. The front vent 6 is in the illustrated embodiment configured as a circular perforation which opens into the second end face 22. The front vent 6 communicates the front chamber with the outside environment, and the front vent 6 is covered with a nonwoven fabric net and a metal net, respectively, in order to prevent foreign matters from invading the inside of the earphone while ensuring ventilation performance. In the embodiment shown, the area of the front vent 6 is about 65mm 2.
Furthermore, as shown in fig. 2 and to 6, the rear chamber comprises an additional wall 4, which additional wall 4 is arranged generally around the earphone driver 3 along the edge of the first housing half 1. The additional wall 4 has an L-shaped cross section, comprising a first additional wall section 41 extending substantially in the thickness direction of the earphone and a second additional wall section 42 extending in the horizontal direction, wherein the first additional wall section 41 is in contact with its free end with the top surface of the first housing half 1 and the second additional wall section 42 is in contact with its free end with the inner side of the first circumferential surface 11 of the first housing half 1, such that the auxiliary channel 5 is formed by the additional wall 4 and the first housing half 1. The auxiliary channel 5 extends generally along an arcuate circumferential portion of the device housing and is configured in a C-shape, in the embodiment shown the auxiliary channel 5 has a width b of 0.9mm and a height h of 2.9mm.
As shown in fig. 3, a first rear vent 71 assigned to the rear chamber is provided on the narrow side of the earphone device close to the ear hook 9. In the illustrated embodiment, the first rear vent 71 is configured as a generally rectangular perforation having an area of about 13mm 2, the first rear vent 71 being covered by a nonwoven web and a metal web. The first rear air opening 71 covers and exceeds the second additional wall section 42 of the additional wall 4 in the thickness direction, so that the first rear air opening 71 also communicates the auxiliary channel 5 with the environment.
As shown in fig. 4, a second rear vent 72 is provided on the narrow side of the earphone device remote from the ear-hook 9. The second rear vent 72 has a significantly smaller area than the first rear vent 71, thereby minimizing the intrusion of external moisture. The second rear vent 72 is located in the first circumferential wall 11 of the first housing half 1 and communicates the auxiliary channel 5 with the external environment. As shown in fig. 5, the second rear vent 72 is located generally farther from the connection section 11 of the ear hook 9 to the device housing, in other words lower, than the center of the first rear vent 71.
Moisture that may exist inside the device case can be discharged from the first rear vent 71 and the second rear vent 72 to the external environment along the C-shaped auxiliary passage 5, which not only improves the ventilation amount of the rear chamber, improves the low frequency effect, but also further improves the waterproof performance of the earphone device because the position of the first rear vent 71 is not easily affected by external moisture.
