Therefore, the accuracy of capturing the motion state of the user by the inertial sensing unit can be improved, the interference of the loudspeaker module is avoided, and the user experience is improved.
The sound emitted by the two speakers 22 enters the front cavity 20 and then is emitted out through the sound outlet 23, and the two speakers 22 are identical speakers and have the same sound pressure level, so that the sound distortion can be effectively reduced.
Two speakers 22 are relative and mirror symmetry sets up, can effectively reduce the space that sets up two speakers 22 and occupy when offsetting the vibration, improve speaker module 2's space utilization.
In one embodiment, as shown in fig. 1, the head-mounted device includes two speaker modules 2, the two speaker modules 2 are respectively located at two sides of the main body portion 1, and the sound outlet holes 23 on the two speaker modules 2 are opposite. The head-mounted equipment further comprises a binding band 3, wherein the binding band 3 is respectively connected with one side, far away from the main body part 1, of the two loudspeaker modules 2.

In one embodiment, the distance between the diaphragms 221 of two of said loudspeakers 22 is greater than twice the maximum displacement of said diaphragms 221.
The speaker 22 emits sound by vibrating the diaphragm 221, and the diaphragms 221 of the two speakers 22 arranged opposite to each other are opposed to each other. During the sound production of the loudspeaker 22, the diaphragm 221 vibrates, and during the vibration, it is displaced in the direction of the other, opposite loudspeaker 22. The distance between the two diaphragms 221 is greater than twice the maximum displacement of the diaphragms 221, and mutual interference between the two diaphragms 221 can be effectively avoided in the sound production process of the two speakers 22.

In the speaker module 2, the ratio of the length direction L to the width W is in the range of 12 to 20, so that the low-frequency diving depth can be effectively increased. Sound can effectively improve the low frequency sound production effect of speaker module 2 after spreading in the inner chamber, improves the experience of user in virtual reality and feels.

In this embodiment, the first sound leaking hole 2111 and the second sound leaking hole 2121 which are mirror-symmetrical are provided, so that the sound leaking positions of the two speakers 22 are symmetrical, the sound leaking is prevented from influencing the vibration cancellation of the two speakers 22, and the vibration cancellation effect of the two speakers 22 is further improved.
In one embodiment, the head-mounted device further comprises an adaptive filter, wherein the adaptive filter detects a first vibration signal of the loudspeaker module and sends out a second vibration signal with the phase opposite to that of the first vibration signal to the inertial sensing unit.
The adaptive filter can sense the diaphragm signal and send out a vibration signal, and besides the two speakers 22 mutually offset the vibration, the speaker module may also have vibration caused by other factors, and may affect the inertial sensing unit. In this embodiment, the adaptive filter senses the vibration of the speaker module and sends out vibration signals with opposite phases to the inertial sensing unit, so as to further reduce the influence of the vibration of the speaker module on the inertial sensing unit.
Optionally, the loudspeaker module generates sound in a frequency range of 20Hz to 20kHz to form the first vibration signal.
The vibration signal emitted in the range is easier to sense by the adaptive filter, and the opposite vibration signal can be accurately emitted. Within this range, a vibration signal generated by the speaker module 2 sounding within the user's hearing range can be formed.
For example, as shown in fig. 3, before the speaker module works, the speaker module is controlled to work in a simulation mode, and a frequency sweep signal required to be sent is obtained, wherein the frequency range of the frequency sweep signal is 20Hz to 20 kHz. The loudspeaker module 2 sends out a sweep frequency signal after being amplified by a circuit, and the first vibration signal generated by the loudspeaker module 2 when the sweep frequency signal is sent out is recorded as x(n). The adaptive filter detects a first vibration signal generated by the loudspeaker module. When the loudspeaker module works, the adaptive filter sends a second vibration signal with opposite phase, which is recorded as h, to the inertia sensing unit according to the first vibration signal(n)。h(n)And x(n)And the vibration generated by the loudspeaker module is counteracted by the mutual counteraction. Therefore, the influence of vibration on the inertial sensing unit can be further reduced, the accuracy of the head-mounted device on sensing the motion state of the user is improved, and the user experience is improved. Adaptive filter sensing x(n)The accuracy of (a) determines the effect of counteracting the vibration, and the error produced by the adaptive filter is denoted as y(n)Wherein, in the step (A),
y(n)＝x(n)+h(n)；
adaptive filter sensing x(n)H emitted later(n)The more accurate, and issue h(n)The smaller the delay of (a), the more y(n)The smaller the value of (b), the better the effect of canceling vibration.
