As shown in fig. 1 to 4, the present embodiment provides a helmet-type earphone, which includes a helmet shell 1, wherein sound generating units are disposed on the top and the side walls of the helmet shell 1, and sound generating ends of the sound generating units are disposed toward the inner space of the helmet shell 1.

In the embodiment, the plurality of sound production units facing the inner space of the helmet shell 1 are arranged in the helmet shell 1, so that sound can be transmitted to human ears from different positions, the real listening environment of the human ears can be simulated, the sound is truly restored, and the helmet shell has the advantages of convenience in use and no influence on other people compared with the existing multi-channel sound.

The sound generating end of the sound generating unit is arranged towards the center of the helmet shell 1. That is, all the sound generating units provided on the helmet shell 1 are provided toward the center of the helmet shell 1. The arrangement mode is closer to the sound receiving habit of the user.

Specifically, each generating unit may represent a sound channel, and the more the sound channels, the higher the degree of restitution of the sound, different generating units may be used to emit different sounds, such as a part of the sound emitting units being used to emit human sound and a part of the sound emitting units being used to emit sound of musical instruments.

In particular, the method comprises the following steps of,

the top of helmet shell 1 is provided with a sound generating unit, and this sound generating unit is top sound generating unit 2, and top sound generating unit 2 sets up along helmet shell 1's axis.

The lateral wall of the helmet shell 1 is provided with a plurality of layers of sounding unit groups, and each layer of sounding unit group comprises a plurality of sounding units.

The arrangement mode of the sound production unit is matched with the radio reception habit of human ears, and the sound effect heard by the human ears is more three-dimensional and more real through the arrangement of the sound production unit on the top and the side wall.

Furthermore, the side wall of the helmet shell 1 is provided with three layers of sounding unit groups, which are respectively an upper layer sounding unit group 3, a middle layer sounding unit group 4 and a lower layer sounding unit group 5.

The multilayer sounding unit groups are arranged at equal intervals.

The front end of the helmet shell 1 is an opening structure 6. The reference plane 13 is a two-part plane which passes through the axis of the helmet shell 1 and can divide the opening structure 6 into two symmetrical parts.

In each layer of sound generating unit group, a plurality of sound generating units are divided into three parts, the sound generating units of the first part and the sound generating units of the second part are in one-to-one symmetry relative to a reference surface, and the sound generating units of the third part are arranged on the side wall of the helmet shell 1 opposite to the opening structure 6.

The first part and the second part of the sounding units respectively comprise 6 sounding units, and the 6 sounding units are respectively a first sounding unit 7, a second sounding unit 8, a third sounding unit 9, a fourth sounding unit 10, a fifth sounding unit 11 and a sixth sounding unit 12;
