[0023] In order to make the utility model purposes, technical solutions and advantages more clearly, the following is combined with the embodiment, and the utility model is further detailed.The specific embodiments described herein are merely used to explain the utility model, and are not used to limit the utility model.
[0024] As Figures 1-4 The utility model embodiment provides a schematic view of hanging ear type earphone, the hanging ear type earphone can be worn to the ear of user, and audio play is carried out.The hanging ear type earphone of this embodiment includes first shell 10, ear hook 20, second shell 30, diaphragm loudspeaker 41, charging battery 42, bone conduction loudspeaker 43 and control circuit board 44, wherein diaphragm loudspeaker 41 includes diaphragm, voice coil, magnetic circuit system etc., voice coil cooperates with magnetic circuit system under the electromagnetic induction and drives diaphragm vibration to produce sound wave through the vibration of diaphragm;Bone conduction loudspeaker 43 directly transmits sound signal to auditory nerve of inner ear through vibrating skull or jaw, thereby realizing the perception of sound;Control circuit board 44 is electrically connected with charging battery 42 and is powered by charging battery 42, and the control circuit board 44 can realize wireless communication, audio decoding etc., and diaphragm loudspeaker 41 and bone conduction loudspeaker 43 are electrically connected with control circuit board 44 respectively and work under the control of control circuit board 44 respectively.Specifically, the above-mentioned diaphragm loudspeaker 41, charging battery 42, bone conduction loudspeaker 43 and control circuit board 44 can adopt the conventional technology in the field, and will not be repeated here.
[0025] First shell 10 is formed with first accommodating cavity, and first shell 10 has sound hole 111 in communication with first accommodating cavity, and diaphragm loudspeaker 41 is installed in first accommodating cavity and sounds through sound hole 111.Second shell 30 is formed with second accommodating cavity, and bone conduction loudspeaker 43 is installed in second accommodating cavity and realizes bone conduction sound through the vibration of second shell 30.
[0026] The ear hook 20 can be an arc structure that fits the user's auricle so that the ear hook 20 can hang on the user's auricle. The first housing 10 is connected to the leading end of the ear hook 20, the second housing 30 is connected to the trailing end of the ear hook 20, and in the wearing state, the middle part of the ear hook 20 (i.e. the part between the leading end and the trailing end) extends along the junction of the user's ear and head, and the second housing 30 is hung on the back of the auricle and the first housing 10 is hung near the ear canal. For example, the ear hook 20 has an arc structure that fits the junction of the user's head and ear, so that the ear hook 20 can be hung between the user's auricle and head. In some embodiments, the ear hook 20 can also be a clamping structure that fits the user's auricle, so that the ear hook 20 can be clamped on the user's auricle. Specifically, the middle part of the ear hook 20 can be hook-shaped and elastic, so that the over-ear earphone is curved in three-dimensional space in the non-wearing state (i.e. the natural state). In other words, in three-dimensional space, the first housing 10, the middle part of the ear hook 20, and the second housing 30 are not coplanar. In this way, when the over-ear earphone is in the wearing state, the middle part of the ear hook 20 can make the first housing 10 contact the front side of the user's ear through its own elastic restoring force, so that the first housing 10 and the middle part of the ear hook 20 cooperate to clamp the ear, and the second housing 10 is attached to the skull on the back of the auricle. In particular, to improve the elasticity of the ear hook 20, the ear hook 20 can have an elastic metal wire inside.

The first front housing 11 and the first rear housing 12 can be respectively fastened to the middle frame 13 (e.g., locked together by a snap-fit mechanism), forming a first accommodating cavity between the first front housing 11, the first rear housing 12, and the middle frame 13. The rechargeable battery 42 is installed in this first accommodating cavity. Similarly, the second housing 30 includes a second front housing 31 and a second rear housing 32. The second front housing 31 and the second rear housing 32 are locked together by a snap-fit mechanism, forming a second accommodating cavity between the second front housing 31 and the second rear housing 32. The control circuit board 44 is installed in the second accommodating cavity. Furthermore, the rechargeable battery 42 and the diaphragm speaker 41 in the first housing 10 are electrically connected to the control circuit board 44 in the second housing 30 via cables passing through the ear hook 20. When the ear-hook headphones are worn on the ears, the first front shell 11 and the second front shell 31 are in contact with the human skin, while the first rear shell 12 and the second rear shell 32 are away from the human body. In practical applications, the first shell 10 and the second shell 30 can also adopt other existing structures, as long as the first shell 10 can accommodate the diaphragm speaker 41 and the rechargeable battery 42, and the second shell 30 can accommodate the bone conduction speaker 43 and the control circuit board 44.

The second front housing 31 and the second rear housing 32 are locked together by a snap-fit mechanism, forming a second accommodating cavity between the second front housing 31 and the second rear housing 32. In this embodiment, the control circuit board 44 is installed in the first accommodating cavity of the first housing 10, and the rechargeable battery 42 is installed in the second accommodating cavity of the second housing 30. The rechargeable battery 42 and the bone conduction speaker 43 are electrically connected to the control circuit board 44 through cables passing through the ear hook 20.
