wherein the plurality of signal receiving components comprise a first signal receiving component, a second signal receiving component, a third signal receiving component, and a fourth signal receiving component, wherein the first signal receiving component and the second signal receiving component are oppositely disposed in the peripheral region along a first direction, wherein the third signal receiving component and the fourth signal receiving component are oppositely disposed in the peripheral region along a second direction, wherein the first direction and the second direction are perpendicular to each other,
wherein the electronic apparatus is virtual reality glasses, wherein the first signal receiving component and the second receiving component each comprise a first preset number of signal receiving devices, wherein the signal receiving device in the first signal receiving component and the signal receiving device in the second receiving component are symmetrical with respect to a center line penetrating through the center region along the second direction, and wherein the first preset number is 7,
where the third signal receiving component and the fourth receiving component each comprise a second preset number of signal receiving devices, wherein the signal receiving device in the third signal receiving component and the signal receiving device in the fourth receiving component are symmetrical with respect to a center line penetrating through the center region along the first direction, and wherein the second preset number is 8,
wherein the electronic apparatus further comprises a control module coupled to the plurality of signal receiving components, wherein the signal receiving device is configured to receive a source signal emitted by a signal emitting source and generate a first signal according to the received source signal, wherein the circuit board is configured to transmit the first signal to the control module, and wherein the control module is configured to obtain spatial position information and/or motion information of the electronic apparatus according to the first signal, and
wherein the signal receiving component is removably attached to the body, wherein the signal receiving device comprises a photodiode, and wherein the circuit board comprises a flexible printed circuit board.

2. The electronic apparatus according to claim 1 , wherein the plurality of signal receiving devices are disposed on the circuit board and towards different directions.

3. The electronic apparatus according to claim 2 , wherein, in the signal receiving component, mounting planes of at least any four of the signal receiving devices are not located on the same plane.

4. The electronic apparatus according to claim 3 , wherein in the signal receiving component, an angle between the mounting planes of the adjacent signal receiving devices is greater than or equal to 120 degrees.

5. The electronic apparatus according to claim 4 , wherein the mounting plane of the signal receiving device is a signal receiving surface of the signal receiving device.

6. A spatial positioning system, comprising:
a signal emitting source configured to emit a source signal; and
the electronic apparatus according to claim 2 .

7. A spatial positioning system, comprising:
a signal emitting source configured to emit a source signal; and
the electronic apparatus according to claim 1 .

8. The spatial positioning system according to claim 7 , wherein the source signal comprises an optical signal, an electrical signal, or an acoustic signal.

9. A method for performing spatial positioning using the electronic apparatus according to claim 1 , comprising:
receiving a source signal emitted by a signal emitting source; generating a first signal according to the received source signal; and
obtaining spatial position information and/or motion information of the electronic apparatus according to the first signal.

10. The method according to claim 9 , further comprising:
before obtaining the spatial position information and/or the motion information of the electronic apparatus according to the first signal, obtaining initial position information and initial orientation information of the electronic apparatus, wherein obtaining the spatial position information and/or the motion information of the electronic apparatus according to the first signal comprises: obtaining the spatial position information and/or the motion information of the electronic apparatus according to an amplitude and a generating time of the first signal, and the initial position information and the initial orientation information of the electronic apparatus.
