Detailed Description

The utility model is further described with reference to the following figures and specific embodiments.

As shown in fig. 1-2, the present embodiment provides a one-ear intercom, which includes a housing 10, an earphone 20 rotatably connected to the housing 10, a hose 30 rotatably connected to the earphone 20, and a hanging ear 40 fixedly connected to an end of the hose 30 far from the earphone 20. Due to the rotary connection between the hose 30 and the earphone 20, the angle of the earphone can be adjusted conveniently when in use, so that a user can wear the interphone on the left ear or the right ear according to actual needs.

The casing 10 is long, and a rotation connecting shaft between the casing 10 and the earphone 20 is arranged perpendicular to the length direction of the casing 10. This facilitates the user to adjust the relative angle between the housing 10 and the headset 20 to change the force applied to the ear by the headset 20, thereby improving the wearing comfort. The housing 10 includes two half-shells fastened to each other, and a control circuit board 11, an antenna 12, a microphone (not shown in the figure), and a key 14 are disposed in the housing 10 and electrically connected to the control circuit board 11, respectively, wherein the antenna is disposed at an upper portion of an inner cavity of the housing 10, and the antenna is preferably a spring-type antenna, which has a relatively small size, a good standing-wave ratio performance, and a good shock resistance. The casing 10 is provided with a sound pickup hole 15 arranged corresponding to the microphone and a through hole for the key to pass through, specifically, the middle part or the upper part of the casing 10 is provided with a long strip-shaped sinking groove 16, and the sound pickup hole 15 is arranged at the bottom of the sinking groove 16, which is helpful for the microphone to receive voice. The keys 14 and the through holes are arranged in a one-to-one correspondence mode, the specific number of the keys and the through holes can be determined according to actual needs, but at least one PTT key is needed, so that the keys can be pressed when voice information needs to be sent.

Preferably, a status indicator lamp 17 electrically connected to the control circuit board 11 is embedded in the casing 10 to facilitate the user to know the operating status of the intercom, and an external connector 18 embedded in the casing 10 is electrically connected to the control circuit board 11, the external connector 18 being located at the lower end of the casing 10, so that the connection of the external connector 18 is not affected even when the intercom is worn on the ear.

The hose 30 is a hollow rubber hose or a hollow silica gel hose, and has certain elasticity. The tube body of the hose 30 is provided with a plurality of ventilation holes 31 communicated with the inner hole of the hose 30, and two ends of the inner hole of the hose 30 are respectively communicated with the inner cavity of the earphone 20 and the inner cavity of the hanging lug 40, so that not only can a certain heat dissipation function be achieved, but also the flexibility of the hose is increased, and the appearance is more attractive.

The hanging lug 40 is provided with a battery 41 electrically connected with the control circuit board 11, and specifically, the control circuit board 11 and the battery 41 are connected through a lead wire which is inserted into the hose 30. The battery 41 with relatively large weight is arranged in the hanging lug 40, and the hanging lug 40 can be hung above the ear when in use, so that the interphone is not easy to fall off. Preferably, a charging port is formed in one end, away from the hose 30, of the hanging lug 40, a charging connector 42 is inserted into the charging port, the charging connector 42 is electrically connected with a power controller 43, and the power controller 43 is electrically connected with the battery 41 so as to charge the battery 41. In addition, the power controller 43 has a power indicator, and the hanger 40 has a light hole 44 at a position corresponding to the power indicator, so that a user can better know the operating state of the power.

The intercom provided by the embodiment is not different from the conventional intercom in use mode except that the intercom is worn on the ear when in use, and the detailed description is omitted here.

The present invention is described in detail with reference to the attached drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention based on the prior art, which fall within the scope of the present invention.
