In the embodiment of the application, the spacer 200 is disposed inside the first housing 100 and is obliquely arranged with the horn 300, so that the horn 300 and the main board 400 are separated between the first chamber 100c and the second chamber 100d, thereby reducing electromagnetic interference between the main board 400 and the horn 300 and increasing the experience of a user.
Specifically, referring to fig. 1 and 2, an embodiment of the present application provides an earphone, which includes a first housing 100, a spacer 200, a speaker 300, and a motherboard 400. The first housing 100 is formed with a mounting cavity 100a and a sound outlet hole 100b, and the sound outlet hole 100b communicates with the mounting cavity 100a and the outside, respectively. The spacer 200 is installed inside the first housing 100 and divides the installation cavity 100a into a first chamber 100c and a second chamber 100d, and the sound outlet holes 100b communicate with the first chamber 100c and the outside, respectively.

Wherein the spacer 200 and the horn 300 are arranged obliquely to each other.
The loudspeaker 300 may also be referred to as a speaker, the loudspeaker 300 being a core component in the headset responsible for converting received electrical signals into sound. The loudspeaker 300 generally comprises a magnet, a voice coil and a diaphragm, wherein when an audio current passes through the voice coil, the voice coil is subjected to a force in a magnetic field generated by the magnet, and the force drives the diaphragm to vibrate, so that sound waves are generated in the air and transmitted to human ears, so that a user can hear the sound.
The main board 400 is a framework for controlling basic functions of playing, pausing, volume adjusting and the like of the earphone, and circuits on the main board 400 are responsible for processing received audio signals, including amplifying, filtering, equalizing and the like, so as to ensure the definition and fidelity of the audio signals. Illustratively, the motherboard 400 may be a PCBA (printed circuit board assembly, printed circuit board), the motherboard 400 generally comprising a plurality of circuit boards.
