All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a head-mounted device according to an embodiment of the present invention.
The head-wearing equipment comprises a host machine 1, a rear cavity shell 2 and a binding band 3, wherein the side surface of the first end of the rear cavity shell 2 is provided with a loudspeaker 4, the second end of the rear cavity shell 2 is connected with one end of the shell of the host machine 1, and the first end of the rear cavity shell 2 is connected with the binding band 3; the side surface of the rear cavity shell 2 provided with the loudspeaker 4 is positioned at the side of the main machine 1.
Specifically, as shown in fig. 1, the head-mounted device in this embodiment may be a VR head-mounted device, and certainly may also be an AR head-mounted device, and the head-mounted device specifically includes two rear cavity housings 2, a second end of each rear cavity housing 2 is connected to one end of the housing of the host computer 1, a first end of each rear cavity housing 2 is connected to the binding band 3, a side surface of the first end of each rear cavity housing 2 is provided with the speaker 4, and the side surface is a side surface of the rear cavity housing 2 located on the side of the host computer 1, that is, the speakers 4 respectively disposed on the left and right rear cavity housings 2 are disposed oppositely. That is, the speaker 4 in this embodiment is not disposed in the housing of the host computer, the rear cavity housing 2 is independently disposed with the host computer housing, and the rear cavity housing 2 is disposed at one end of the host computer housing, so that the bandage 3 is connected with the host computer housing through the rear cavity housing 2, as shown in fig. 1, the head-mounted device in this embodiment is worn by the user, because the speaker 4 is disposed at the side of the first end connected with the bandage 3 on the rear cavity housing 2, therefore, the speaker 4 can be close to the ear of the user, so that the sound emitted by the speaker reaches the ear of the user as much as possible, the left side speaker is close to the left ear, and the right side speaker is close to the right ear, therefore, compared with the prior art, the speaker is disposed in the host computer housing of the host computer and the sound through hole is opened on the host computer housing, the isolation between the high-.
For convenience of users, the second end of the rear cavity housing 2 in this embodiment may be connected to one end of the housing of the host 1 through a rotating shaft, and certainly, in practical application, the rear cavity housing is not limited to be connected through a rotating shaft, and may also be connected in other manners, and this embodiment is not particularly limited. In addition, the first end of the rear cavity housing 2 can be connected with the connecting piece on the binding band 3 in a buckling or screw mode, and the specific connection mode can be determined according to the actual situation.
Furthermore, the front cavity housing 41 of the speaker 4 in this embodiment may further be provided with a sound through hole 42 to realize front cavity sound emission, and the maximum aperture ratio is adopted to reduce the volume of the front cavity as much as possible, so as to improve high frequency ductility and further improve high frequency directivity. Specifically, the front cavity housing 41 in this embodiment may be provided with a plurality of sound holes 42, wherein the front cavity housing 41 is shown in fig. 2, and the sound holes 42 are shown in fig. 3.
Further, the rear cavity housing 2 in this embodiment may be specifically configured as a flat and long housing. In addition, the binding band 3 may be provided as an elastic binding band or may be provided as a rigid binding band, and if the binding band 3 is provided as a rigid binding band, the rear cavity housing 2 may be provided as a part of the binding band 3 or the rear cavity housing 2 may be embedded in the binding band 3.
Since low frequency sounds such as music, rumble, explosions, gunshot, and heartbeat sounds are often present in VR and entertainment content, bass is important to convey the sense of size and scale, which enhances the visual immersion of the VR and can elicit specific emotional cues such as danger, isolation, etc., it is important that the listening component provide a sufficient low frequency response. Therefore, in the present embodiment, the rear cavity housing 2 is configured to be flat and long, and the through hole 21 is provided on the second end side of the rear cavity housing 2, wherein the side may be a side opposite to the side where the horn 4 is provided, so that the rear cavity housing 2 is configured to be an open rear cavity, specifically, the through hole 21 in the present embodiment may be multiple (as shown in fig. 4), and the total opening area of each through hole 21 may be smaller than the minimum cross-sectional area of the rear cavity housing 2, wherein the area covered by each through hole 21 may be a rectangular area (of course, other shapes may also be used, and the present embodiment is not particularly limited), so that while the open rear cavity housing design is implemented to improve the low-frequency effect, dust and the like can be prevented from entering the rear cavity. The low-frequency resonant frequency F0 of the speaker can be calculated by the following formula:
F0＝1/(2π(Mms*Cms)0.5) Wherein M ismsTo the equivalent mass of the vibrating system, CmsIs the compliance of the vibration system. In the electric power sound analogy, the closed rear cavity of the loudspeaker in the acoustics is equivalent to an air spring in mechanics, and the air spring is connected with an elastic system of a loudspeaker body in parallel, so that the sequence C of a vibration system is realizedmsTherefore, after the loudspeaker in the prior art design has the rear cavity added, the F0 of the vibration system is higher than the F0 of the horn cell itself, and the low frequency is damaged. In the embodiment, the back cavity of the loudspeaker is designed by adopting a flat and long strip-shaped pipeline, the mass of air in the back cavity is equivalent to the mass M in mechanics, and the mass M is equivalent to the mass M in the formulamsTherefore, F0 can be reduced to some extent in this embodiment, and the low-frequency response is improved.
Specifically, referring to fig. 5, taking F0 as an example of a 500Hz horn unit, frequency response curves measured by respectively installing the horn unit in a closed rear cavity and an open flat-long rear cavity in the present embodiment, where a curve a is a frequency response curve corresponding to the closed rear cavity, and a curve b is a frequency response curve corresponding to the developed rear cavity, it can be seen from comparison that the rear cavity housing design method provided in the present embodiment can greatly improve the low frequency effect under the condition of limited space (e.g., the example low frequency improvement corresponding to fig. 5 is more than 7 dB). In addition, the effect that the low-frequency resonance frequency of the system is lower than that of the monomer F0 can be realized through design.
It is thus clear that the back chamber shell in this application is independent sets up with the host computer, and the back chamber shell sets up between host computer and bandage, the first end side of connecting the bandage on the back chamber shell sets up loudspeaker, and this side is located the host computer side, thereby can make the user wear to wear behind the VR equipment loudspeaker to be nearer apart from user's ear, can improve high frequency directive property and control the sound channel isolation to a certain extent for prior art, promote product stereo effect, further improve user experience.
