Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, it is a schematic structural diagram of the bluetooth headset provided by the embodiment of the present invention, and this bluetooth headset can be applied to the field of headset devices, especially in bone conduction headsets. Referring to fig. 2, the bluetooth headset in this embodiment includes a bone conduction speaker 1 and a vibration transmitting member 2, wherein the bone conduction speaker 1 is mainly configured to generate vibration under excitation of an electrical signal, and transmit the vibration through the vibration transmitting member 2, so as to implement bone conduction speech transmission.

In order to ensure that the vibration transmission piece 2 can transmit the sound generated by the bone conduction loudspeaker 1, the vibration transmission piece 2 is connected with the bone conduction loudspeaker 1, so that the vibration generated by the bone conduction loudspeaker 1 can be transmitted to the human tissue attached to the vibration transmission piece 2, namely, the bone conduction loudspeaker 1 generates vibration under the excitation of an electric signal and drives the vibration transmission piece 2 to vibrate integrally; when the user wears the bluetooth headset, the vibration transmission piece 2 can transmit vibration to auditory nerves through the skull of a person, and then the user can hear the sound played by the bluetooth headset. The vibration transmission member 2 is preferably integrally formed of an elastic material (e.g., rubber), and is convenient and quick to process and operate, low in material cost, and suitable for mass production.

In addition, the vibration transmission member 2 may be directly attached to the vibration portion of the bone conduction speaker 1, so as to improve the vibration transmission effect. Of course, in practical applications, the vibration transmission member 2 may also be indirectly connected to the vibration portion of the bone conduction speaker 1, for example, to be respectively attached to the shells of the bluetooth headset, so as to transmit the vibration through the shells; the specific design can be determined according to actual conditions.

Particularly, the side surface of the vibration transmission member 2 facing away from the bone conduction speaker 1 has a first avoidance groove 21 adapted to the human crus of helix, so that when the vibration transmission member 2 is worn on the ear of the human body, the crus of helix of the human body can be embedded into the first avoidance groove 21 and is attached to the inner wall of the first avoidance groove 21. Moreover, a first convex portion 22 and a second convex portion 23 are respectively formed on both sides of the vibration transmitter 2, and the first convex portion 22 is adapted to the cavum concha of the human body, and the second convex portion 23 is adapted to the cymba concha of the human body.

Because human helix is protruding structure (being higher than the diapire of concha chamber and concha ship), consequently set up first groove 21 of dodging and make human helix imbed first groove 21 of dodging to can make first convex part 22 imbed the human concha intracavity, and make second convex part 23 imbed in the human concha ship, prevent that human helix shore from to pass and shake piece 2 and organize first convex part 22 and insert the concha chamber and the insert the concha ship of second convex part 23.
