Referring to fig. 1-3, the in-ear earphone of the present utility model is an earphone having two listening modes of bone conduction and air conduction, and the in-ear earphone includes a main body, wherein the main body is composed of a listening portion 2 and a storage portion 1, a sound outlet 200 is provided at the end of the listening portion 2, the sound outlet 200 corresponds to the interior of the ear canal after being worn in the ear canal, and in addition, the sound outlet 200 is formed by extending the sound canal in the listening portion 2 out of the end of the listening portion 2, so that a transmission path for pushing sound from a generating unit into the ear canal is formed.

Within the listening portion 2, the listening portion 2 is designed with the result of being accommodated in the ear canal,

the apparent volume of the listening portion 2 is gradually reduced compared to the storage portion 1;

in the storage part 1, a bone conduction unit is provided, which is provided with a vibration plate that beats the first side 101 of the storage part 1 in the case of high-speed back and forth vibration, so that the first side 101 generates vibration of the same frequency and then transmits to the skull bone, in other words, the vibration signal is transmitted to the auditory nerve, and the stimulation signal generated to the auditory nerve can be converted into actually generated sound by the internal tissues of the human body.

In this embodiment, the bone conduction unit located in the storage portion 1 mainly assists the air conduction type listening to use, outputs a low frequency pulse signal, and improves the situation that the low frequency mixing thickness is absent in the sound in the air conduction type.

Therefore, the in-ear earphone of the utility model can obviously improve the sound output effect,

repairing the defect existing in the gas conduction type.

In this embodiment, the storage part 1 is located within the scope of the ear hub and is held on the ear in such a way that the first side 101 contacts the temporal bone in the ear canal after being worn on the ear, so as to make the whole in-ear earphone more compact in structure in order to increase the use of limited space, and can avoid pain caused by the extrusion of the auricle compared with the way of hanging on the outline of the ear and contacting the temporal bone outside the auricle.

In the present embodiment, the sound generating unit in the storage section 1 is composed of the following units:

the low frequency part is a moving coil unit responsible for the low frequency band,

the intermediate frequency part is a first moving iron unit responsible for the intermediate frequency band;

the high-frequency part is a second moving iron unit responsible for the high frequency band;

the ultrahigh frequency part is an electrostatic unit responsible for the ultrahigh frequency band.

The storage part 1 is divided into a plurality of independent cavities of each unit, the soundtrack is provided with a plurality of channels and is respectively communicated with the cavities (a first cavity 1001 corresponding to the moving coil unit, a second cavity 1002 corresponding to the first moving iron unit, a third cavity 1003 corresponding to the second moving iron unit, a fourth cavity 1004 corresponding to the static electricity unit and a fifth cavity 1005 corresponding to the bone sensing unit), and in actual use, channel sound waves generated by each unit flow out of the sound outlet 200 along the soundtrack.
