The utility model provides an at least one let out the sound hole still has been seted up on the intelligence head-mounted apparatus.

In one embodiment, as shown in fig. 4-6, a main sound venting hole 6 is provided in the leg 1. A cavity 13 is formed in the leg 1, the cavity 13 is communicated with the sound emitting structure 41, and the sound emitting device 3 is located in the cavity 13. The sound generating device 3 separates the cavity 13 into a rear sound cavity and a front sound cavity communicated with the sound emitting structure 41, the main sound releasing hole 6 is communicated with the rear sound cavity, and the main sound releasing hole 6 and the sound emitting structure 41 are structured as follows: for creating an acoustic dipole effect when the sound generating means 3 generates sound.

Through set up sound generating mechanism 3 in the cavity 13 of shank 1, realized the open coupling of sound generating mechanism 3 with earhole 7, compared the airtight coupling form of pleasant formula, the open coupling is worn convenient comfortable and the structure is simplified, and the appearance is pleasing to the eye to the user can the external developments of real-time perception, security when having improved this intelligence head-mounted apparatus and using. However, the disadvantage of this open coupling is also obvious, since the sound source is diffused outwards, so people around the user can also hear the sound emitted by the sound emitting device of the smart headset, which is not good for protecting the privacy of the user and can interfere with others. Therefore, the utility model discloses offer the sound cavity in the front with sound emitting structure 41, offer main hole 6 of letting out on the sound cavity of back simultaneously, because preceding sound cavity and back sound cavity are located the both sides of sound generating mechanism 3's vibrating diaphragm respectively. Thus, for example, when the diaphragm vibrates in the direction of the front acoustic chamber, the air in the front acoustic chamber is compressed, while the air in the rear acoustic chamber just expands. The sound source of the front sound cavity, i.e. the sound outlet structure 41, and the sound source of the rear sound cavity, i.e. the main sound leakage hole 6, have opposite phases, so that a positive and negative sound pressure phase is formed, which is equivalent to the formation of an acoustic dipole effect. The acoustic dipole is a synthesized sound source composed of two point sound sources which are close to each other and have the same vibration amplitude but opposite phases. And the utility model discloses an intelligence head-mounted apparatus has just utilized the reverse phase position of sound dipole to fall the hourglass principle for sound that sound structure 41 and main two sound sources of leaking sound hole 6 sent offsets each other in a distance, reaches the purpose of falling the hourglass. Generally, when the distance between the sound outlet structure 41 and the main sound leakage hole 6 is much smaller than the distance between the sound outlet structure 41 and the main sound leakage hole 6 to the ear holes of the surrounding listeners, the sound outlet structure 41 and the main sound leakage hole 6 can form an acoustic dipole effect.

In one embodiment the distance between the main sound outlet hole 6 and the sound outlet structure 41 is less than 30 mm. It is desirable for people around the user that the sound leakage is as small as possible, i.e. that an acoustic dipole is formed between the main sound leakage hole 6 and the sound emitting structure 41. This just requires that the distance between main hole 6 of leaking out and sound structure 41 can not be too far away, and from the actual use condition of intelligent glasses, the utility model discloses when the people discover that the distance between main hole 6 of leaking out and sound structure 41 is less than 30mm, the effect that the sound was eliminated that leaks out is best.

In one embodiment, the distance between the main sound venting hole 6 and the user's ear hole 7 is larger than the distance between the sound emitting structure 41 and the user's ear hole 7. The anti-phase sound waves of the main sound outlet 6 are attenuated for the loudness of sound received by the human ear. That is, the sound waves emitted from the main sound outlet 6 partially cancel the sound waves emitted from the sound emitting structure 41, thereby affecting the listening effect of the user. In order to reduce this weakening effect, the present invention finds that the distance from the main sound outlet 6 to the human ear needs to be larger than the distance from the sound emitting structure 41 to the human ear.

In one embodiment, the distance between the main sound venting hole 6 and the user's ear hole 7 is defined as a first distance, the distance between the sound generating structure 41 and the user's ear hole 7 is defined as a second distance, and the difference between the first distance and the second distance is larger than 5 mm. The utility model discloses when the difference of above-mentioned two distances is greater than 5mm, sound structure 41 and main two sound sources of letting out sound hole 6 are unsatisfied for user's earhole 7 and are formed the condition of sound dipole effect, consequently just can reduce the influence to the user. That is, for the people around the user, the sound emitting structure 41 and the main sound leaking hole 6 form an acoustic dipole effect to reduce the sound leakage. Compared with the user himself, the two sound sources of the sound outlet structure 41 and the main sound leaking hole 6 cannot form an acoustic dipole effect, so that the listening effect of the user is not affected.

In one embodiment, the rear sound cavity may be further opened with a secondary sound release hole, and the distance between the secondary sound release hole and the ear hole 7 of the user is greater than the distance between the primary sound release hole 6 and the ear hole 7 of the user. After the rear cavity is provided with the main sound leakage hole 6, for a user, two sound sources are actually formed, and because the structures of the front sound cavity and the rear sound cavity are different, the positions of high-frequency cut-off Frequencies (FH) formed by the two sound cavities are also different, so that a Frequency Response (FR) curve forms a double-peak structure at a high frequency. And the double peaks can be combined into one by adjusting the size of the rear sound cavity, or adjusting the size and the position of the sound leakage holes, or additionally arranging the sound leakage holes. And through opening the vice hole of letting out sound to the back sound cavity, utilize vice hole of letting out sound to adjust the Frequency Response (FR) curve of the main hole of letting out sound 6 of back sound cavity, make its high frequency cut-off Frequency (FH) and go out the high frequency cut-off Frequency (FH) of sound structure and be close or unanimous to improve the sound effect.

In one embodiment, the primary sound outlet 6 and the secondary sound outlet are both slit-shaped, and the size of the primary sound outlet and the size of the secondary sound outlet are both not more than 1.5 × 8mm, and the size of the secondary sound outlet is preferably smaller than that of the primary sound outlet 6; in other embodiments, the primary sound venting holes 6 and the secondary sound venting holes may also have other shapes, such as circular, etc.
