Since electronic components such as the power supply and processing module are arranged at both ends of the surround structure, their physical circuits such as wires are connected through the interior of the surround assembly 112, allowing signal transmission between the mainboard 121 and each module. Specifically, the wires inside the surround component 112 can respectively connect the power supply structure 115 with the mainboard 121 to realize power supply, and respectively connect the signal acquisition element 11 and the signal playback element 12 inside the left earphone head 101 to the mainboard 121, so that they can communicate with the mainboard 121 and realize signal transmission.

[0051] In some embodiments, according to product design and user requirements, a switch button and an adjustment button can also be installed on one end of the surround component 112 where the main board 121 is provided, so that the user can adjust the volume, speed and other attributes of the recorded and played sound according to needs, thereby improving the user experience.

[0052] Figure 8The internal structure of the left earphone head 101 is taken as an example. The left earphone head 101 and the right earphone head 102 have symmetrical structures, and the front ends of the left earphone head 101 and the right earphone head 102 are sleeved with earplugs 113, which are used to provide a better user experience when the earplugs 113 are inserted into the ears. The tail ends of the left earphone head 101 and the right earphone head 102 are both provided with through holes 114, which are in communication with the outside world and are used to receive external sounds. Through sound collection in different directions of the left earphone head 101 and the right earphone head 102, the sound field signals obtained can be synthesized and the surround sound effect can be achieved. The signal collection element 11, i.e., the microphone, is arranged on one side of the left earphone head 101 and the right earphone head 102 close to the through hole 114, and the signal playback element 12, i.e., the loudspeaker, is arranged on the other side of the left earphone head 101 and the right earphone head 102 away from the through hole 114. According to actual conditions, a layer of sound-absorbing cotton can be arranged on the side of the signal collection element 11 close to the through hole 114 to reduce the influence of reflection and noise and ensure the sound quality during recording.

[0053] With reference to Figures 7-10 The signal collection element 11 and the signal playback element 12 are electrically connected with the main board 121, and according to actual conditions, the signal collection element 11 and the signal playback element 12 are connected with the main board 121 through a circuit board and wires. Taking the case that the main board 121 is arranged on the right side of the surround assembly 112 as an example, for the right earphone head 102, the signal collection element 11 and the signal playback element 12 in the right earphone head 102 are connected with the main board 121 through the wires arranged in the right connecting line 104; for the left earphone head 101, the signal collection element 11 and the signal playback element 12 in the left earphone head 101 are connected with the main board 121 through the wires arranged in the left connecting line 103 and extending to the left end of the surround assembly 112, the wires winding along the middle part of the surround assembly 112 and finally connecting with the main board 121.

[0054] The embodiment of the present application provides a surround sound recording system, which comprises an earphone and a receiver. The receiver comprises a second transmitting and receiving unit, a signal processing unit and a terminal transmission unit. The receiver is in wireless communication connection with the earphone through the second transmitting and receiving unit, and is in pluggable connection and communication connection with a terminal device through the terminal transmission unit. The signal processing unit processes the received signals and sends them to the terminal device for storage or to the earphone for playing according to actual conditions. The earphone and the receiver are used in cooperation, so that a user does not need to download special software when using the product, but can use the terminal device to record surround sound through the connection between the receiver and the terminal device, thereby improving the convenience and practicality of the product and the user experience.

[0055] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
