[0013] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0014] like Figure 1 and Figure 2 As shown, the present invention provides an earphone based on directional sound technology, which includes an elastic silicone neck pendant 1, mounting cavities 2 respectively arranged at both ends of the elastic silicone neck pendant 1, and a directional sound-emitting device 4 connected to the mounting cavity 2, a directional sound-emitting hole 41 is provided on the directional sound-emitting device 4, an electronic mainboard 21, a battery 22, a USB charging interface 23, and a button 24 are arranged in the mounting cavity 2, and a universal ball head 3 is provided at the connection between the mounting cavity 2 and the directional sound-emitting device 4.

[0015] The present invention uses the universal ball head 3 to allow the connection position between the installation cavity 2 and the directional sound-emitting device 4 to be rotated and adjusted in angle, thereby allowing the directional sound-emitting hole 41 to be aligned with the ear.

[0016] Furthermore, both ends of the elastic silicone neck pendant 1 are connected to the installation cavity 2; an electronic mainboard 21, a battery 22, a USB charging interface 23, and a button 24 are installed in the installation cavity 2; the electronic mainboard 21 and the battery 22 are electrically connected; the USB charging interface 23 and the button 24 are both arranged on the electronic mainboard 21; waterproof parts are arranged at the connection between the USB charging interface 23 and the button 24 and the electronic mainboard 21; the directional sound device 4 is connected to the electronic mainboard 21 and is controlled by the electronic mainboard 21. By using silicone material, the elastic silicone neck pendant 1 can be bent and deformed, adapted to different users, and improve the user's comfort, and its practicality is high.

[0017] Furthermore, the installation cavity 2 and the directional sound-emitting device 4 are connected via a universal ball head 3, and a directional sound-emitting hole 41 is provided at one end of the directional sound-emitting device 4 away from the installation cavity 2. The directional sound-emitting hole 41 can realize the directionality of sound propagation to the ear canal, and the sound is not easy to diffuse.

[0018] Directional sound technology is a groundbreaking audio solution that provides an effective way to propagate sound. It can project sound in a highly directional manner to a specific area without the use of a large speaker array, creating a specific audio space. It allows sound to propagate in a specified direction in the form of a narrowband sound wave beam, that is, sending a "sound column", similar to the light column emitted by a searchlight, so that only people in the direction covered by the light column can hear the sound. This technology that allows sound to propagate in a certain direction is directional sound technology. Simply put, directional sound technology uses the directional characteristics of ultrasound and uses unique acoustic technology and algorithms to achieve that audible sound can also propagate in a specified direction.

[0019] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
