As shown in Figure 1 to Figure 3, the speaker in an embodiment includes shell 200 and the loudspeaker that are arranged in shell 200
230, the inner space of shell 200 is separated into preceding sound chamber 210 and rear sound chamber 220, and rear sound chamber 220 is by above-mentioned loudspeaker 230 with before
Sound chamber 210 is isolated, and offers the first paraphase hole 202 and the second paraphase hole 203, the second paraphase hole 203 on the side wall of rear sound chamber 220
Compared with the first paraphase hole 202 closer to loudspeaker 230, go out acoustic aperture 201 before offering on the side wall of preceding sound chamber 210.
Above-mentioned speaker is opened on the side wall of rear sound chamber 220 by going out acoustic aperture 201 before opening up on the side wall of preceding sound chamber 210
If the first paraphase hole 202 and the second paraphase hole 203, the second paraphase hole 203 compared with the first paraphase hole 202 closer to loudspeaker 230, thus
Two groups of irregular paraphase paths can be formed: (i.e. path b) shown in Fig. 4 is from the 230 to the first paraphase of loudspeaker in one group of path
Hole 202, path is longer, main lift low frequency；(i.e. path c) shown in Fig. 4 is fallen from loudspeaker 230 to the second in another group of path
Phase hole 203, path is relatively short, mainly improves intermediate frequency.The partial radiation acoustic pressure of loudspeaker 230 by above-mentioned two groups it is irregular fall
The acoustic pressure of special frequency channel and the acoustic pressure of preceding acoustic aperture 201 out are overlapped respectively, it is acoustic to reach special frequency channel by phase path
It is promoted, sense of hearing is more preferable.
As shown in figure 3, rear sound chamber 220 includes sound chamber 221 after first, go out after being offered on the side wall of sound chamber 221 after first
Acoustic aperture 204 goes out acoustic aperture 204 compared with the first paraphase hole 202 and the second paraphase hole 203 closer to loudspeaker 230 afterwards.Further, rear sound
Chamber 220 further includes sound chamber 222 after second, and sound chamber 222 is connected with sound chamber 221 after first after second, the first paraphase hole 202 and
After two paraphase holes 203 are opened in second on the side wall of sound chamber 222.
Preceding sound chamber 210 is set to the front side of loudspeaker 230, and face loudspeaker 230 in one of the embodiments,；Sound after first
Chamber 221 is located at the rear side of loudspeaker 230, and face loudspeaker 230.Specifically, afterwards go out acoustic aperture 204 be arranged after first sound chamber 221 with
On the opposite side wall in the back side of loudspeaker 230, so that sound can directly be radiate from the acoustic aperture that goes out at 230 back side of loudspeaker, it can make
Sound field is openr.
Optionally, the opening direction of the first paraphase hole 202 and the second paraphase hole 203 is parallel to each other.An implementation wherein
In example, opening direction of the opening direction of the first paraphase hole 202 and the second paraphase hole 203 respectively with rear acoustic aperture 204 out mutually hangs down
Directly.
As shown in Fig. 2, speaker further includes the circuit board 240 being arranged in shell 200 and the electricity for powering for loudspeaker 230
Pond 250, battery 250 and loudspeaker 230 are electrically connected with circuit board 240 respectively.
To sum up, the preceding sound chamber 210 of the utility model speaker uses side principle of sound, i.e., the preceding acoustic aperture 201 out of preceding sound chamber 210
It is arranged on the side wall of preceding sound chamber 210；The rear sound chamber 220 of speaker, which is divided into two parts, to be handled: first part is positive sounding, from loudspeaker
230 back sides it is rear go out acoustic aperture 204 (i.e. the path a) shown in Fig. 4 is directly radiate, and sound field can be made openr；Second
Part is using inverted phase type principle, by the partial radiation acoustic pressure at 230 back side of loudspeaker by two groups of irregular paraphase paths, respectively
The acoustic pressure of special frequency channel is overlapped with the acoustic pressure for going out acoustic aperture 201 before preceding sound chamber 210, it is acoustic to reach special frequency channel
It is promoted.Two groups of irregular paths respectively correspond are as follows: (i.e. path b) shown in Fig. 4 is from 230 back side of loudspeaker to for one group of path
One paraphase hole 202, path is longer, and main lift low frequency makes low frequency more have texture；Another group of path (i.e. path shown in Fig. 4
It c) is from 230 back side of loudspeaker to the second paraphase hole 203, path is relatively short, mainly improves intermediate frequency, keeps intermediate frequency fuller.Loudspeaker
Partial radiation acoustic pressure by this two groups irregular paraphase paths, respectively by the acoustic pressure of special frequency channel and it is preceding go out acoustic aperture acoustic pressure
It is overlapped, reaches the acoustic promotion of special frequency channel, sense of hearing is more preferable.
The invention also discloses a kind of glasses.As shown in Figure 1 to Figure 2, the glasses of an embodiment include spectacle frame
(not shown), the leg of spectacles connecting with spectacle frame and the speaker being arranged on leg of spectacles, the speaker are described in the utility model
Speaker.By the way that above-mentioned speaker is arranged on leg of spectacles, it is able to ascend acoustics, sense of hearing is more preferable, and user experience is more preferable.
Specifically, the loudspeaker 230 of speaker are arranged close to leg of spectacles 100, and the preceding acoustic aperture 201 out of speaker is arranged in shell 200
On the position of auricle, by the way that shell 200 is arranged on the position of auricle in preceding acoustic aperture 201 out, go out acoustic aperture 201 before making
Always closer distance is kept with human ear, so that sound is become smaller in the overall attenuation of propagation path, so as to protect under the conditions of small volume
Good sense of hearing is held, and reduces the interference to personnel beside user when in use.
Specific in the present embodiment, speaker includes left eye temple, right eye temple, left eye frame and right eye frame, left eyeglass lens
Leg is connect with left eye frame, and right eye temple is connected with right eye frame, and left eye frame is connected with right eye frame, left eye temple and the right side
