The following describes the headset head and the wireless headset in detail according to various embodiments of the present application with reference to the accompanying drawings.

As shown in fig. 1-3, which are schematic structural diagrams of an earphone head provided by an embodiment of the present invention, the earphone head is used for playing audio data. The earphone head 10 of the present embodiment includes a main housing 11 and two diaphragm sound generating devices 12, wherein the diaphragm sound generating devices 12 are installed in the main housing 11 and can convert an electrical signal into sound to be played (for example, the diaphragm is vibrated and generates sound by controlling the change of a magnetic field). The two vibrating diaphragm sound-generating devices 12 may have the same specification, and in practical applications, the two vibrating diaphragm sound-generating devices 12 may have different specifications, for example, the two vibrating diaphragm sound-generating devices 12 have different sizes, and/or the sound-generating frequency ranges of the two vibrating diaphragm sound-generating devices 12 are different (for example, the high-pitched sound-playing effect of the vibrating diaphragm sound-generating device 12 is better, and the low-pitched sound-playing effect of the other vibrating diaphragm sound-generating device 12 is better), and the like. The main housing 11 has a certain hardness, and may be made of plastic material, metal material or mixed material, and protects the vibrating diaphragm sound-generating device 12 therein. In practical applications, the diaphragm sound-generating device 12 may be a loudspeaker, and the number of the diaphragm sound-generating devices 12 may be more than two, for example, three, four, etc., without limitation.

In the present embodiment, each vibrating diaphragm sound-generating device 12 has a sound-generating surface, which is a sound-generating surface of the vibrating diaphragm sound-generating device 12, for example, the sound-generating surface may be a front surface of a loudspeaker. The main housing 11 has two directional sound leading ports 113 thereon, and the earphone head 10 is worn on the face of the human body in such a manner that both directional sound leading ports 113 face the auricle of the human body. Correspondingly, the main housing 11 has two mounting grooves 114 therein, the shape and size of the mounting grooves 114 are matched with the shape and size of the vibrating diaphragm sound-generating devices 12, the two vibrating diaphragm sound-generating devices 12 are respectively mounted in the two mounting grooves 114, and an internal sound cavity 15 is formed between the sound-generating surface of each vibrating diaphragm sound-generating device 12 and the bottom wall of the corresponding mounting groove 114; the two internal sound cavities 15 are independent of each other, and each internal sound cavity 15 is communicated with the outside through a directional sound leading port 113. When the number of the diaphragm sound generators 12 in the earphone head 10 changes, the number of the directional sound guide ports 113 and the number of the mounting grooves 114 also need to be adjusted accordingly, that is, the number of the directional sound guide ports 113 and the number of the mounting grooves 114 are the same as the number of the diaphragm sound generators 12.

The above-mentioned earphone head 10 can be worn near user's ear through hanging the arm, neither need to fill in the auditory canal, also need not openly to extrude the auricle of the wearer, and only need to paste main casing 11 in human face to make directional sound guide port 113 towards the auricle, thereby the sound of being sent out by the sound production face of vibrating diaphragm sound generating mechanism 12 is transmitted to the auricle on through interior sound cavity 15 and directional sound guide port 113, and sound transmits to the auditory canal after auricle reflection. Compared with other earphones provided with a plurality of densely distributed sound outlet holes, the earphone head 10 leads out the sound emitted by the vibrating diaphragm sound generating device 12 from the directional sound guide port 113 in a centralized manner, reduces the diffusion and loss of the sound, improves the sound quality, and meanwhile, can prevent the sound from being discharged outside, and improves the privacy.

For the earphone head using a single diaphragm sound generating device, the earphone head 10 can improve the volume of the sound played by the earphone head by setting a plurality of diaphragm sound generating devices 12 in the main housing 11 and setting a plurality of directional sound guide ports 113 thereon, on the other hand, the audio playing control of each diaphragm sound generating device 12 can be matched (for example, the audio playing content and volume of each diaphragm sound generating device 12 are controlled), and meanwhile, because the internal sound cavities 15 at the front ends of the diaphragm sound generating devices 12 are mutually independent, the sound emitted by each diaphragm sound generating device 12 is mixed at the auricle, the stereoscopic impression of the audio playing is improved, and the sound effect is improved.

In addition, since the ear canal cannot be directly blocked, when the wearer uses the earphone with the earphone head 10, the wearer can receive other sounds from the outside, the alertness of the wearer is improved, and particularly the wearer can walk and ride on the road more safely. The main housing 11 may further include a circuit board 13, and the circuit board 13 may be integrated with a key and a microphone, so as to realize sound playing control and external sound input.

Particularly, a filter screen can be installed at the position of the directional sound guiding port 113, and the filter screen can be made of a waterproof sound-transmitting material, such as a waterproof sound-transmitting sticker or a waterproof sound-transmitting film, so that the waterproof and dustproof capabilities of the earphone head are greatly improved.

In an embodiment of the present invention, the main housing 11 further has an outer sound cavity 16 therein, and one side of each vibrating diaphragm sound generating device 12 facing away from the sound generating surface is located in the outer sound cavity 16, i.e. each vibrating diaphragm sound generating device 12 shares one outer sound cavity 16. Meanwhile, the main housing 11 has a pressure release hole communicating the external sound cavity 16 with the outside, and the air flow generated by the vibration of the vibration sound generating device 12 can be oscillated in the external sound cavity 16 through the external sound cavity 16 and the pressure difference between the inside and the outside can be balanced through the pressure release hole, so that the sound effect of the internal sound cavity 15 and the directional sound guide port 113, especially the effect of the bass part, can be greatly improved.

In particular, to improve the sound generating effect of the earphone head 10 and avoid the occurrence of sound leakage or sound breakage at the pressure relief opening, the external sound cavity 16 may be divided into two independent parts by the circuit board 13, wherein one part is located between the main housing 11 and the circuit board 13, and the other part is located between the circuit board 13 and the vibrating diaphragm sound generating device 12. Meanwhile, the circuit board 13 is provided with a through hole 131, an air guide 14 is fixed on the circuit board 13 facing the surface of the vibrating diaphragm sound generating device 12, a spiral air guide channel 141 is arranged on one side of the air guide 14 facing the circuit board, and an inlet of the air guide channel 141 is positioned at the edge of the air guide 14, and an outlet of the air guide channel 141 is positioned at the center of the air guide 14 and communicated with the through hole 131.

Thus, when the vibrating diaphragm sound-generating device 12 vibrates to generate high air pressure between the circuit board 13 and the vibrating diaphragm sound-generating device 12, the air flow flows out between the main casing 11 and the circuit board 13 through the relatively long air guide channel 141 and the through hole 131, and then flows out of the main casing 11 through the pressure relief hole on the main casing 11; when the vibrating diaphragm sound-generating device 12 vibrates to generate a low air pressure between the circuit board 13 and the vibrating diaphragm sound-generating device 12, the air outside the main case 11 enters between the main case 11 and the circuit board 13 through the pressure relief hole on the main case 11, and then enters between the circuit board 13 and the vibrating diaphragm sound-generating device 12 through the through hole 131 and the air guide channel 141.

Above-mentioned air guide channel 141 can cushion the air current of business turn over pressure release hole for the atmospheric pressure between circuit board 13 and the vibrating diaphragm sound generating mechanism 12 changes for a relatively little, thereby avoids vibrating diaphragm sound generating mechanism 12's vibration range too big, promptly through above-mentioned circuit board 13, air guide 14, can make vibrating diaphragm sound generating mechanism 12 vibrate at predetermineeing the within range, thereby improves the sound production effect of earphone head 10. Meanwhile, because the air flow entering and exiting the pressure relief hole is relatively small, the sound leakage or sound breaking at the pressure relief hole can be avoided to a certain extent.

In an embodiment of the present invention, each directional sound guiding port 113 runs through a bottom wall corresponding to the mounting groove 114, and when each vibrating diaphragm sound generating device 12 is installed to the corresponding mounting groove 114, the sound emitting surface of each vibrating diaphragm sound generating device 12 faces the directional sound guiding port 113 corresponding to the bottom wall of the mounting groove 114, so that the sound emitted by the vibrating diaphragm sound generating device 12 can be more directly conducted to the outside of the main casing 11.

In an embodiment of the present invention, the main housing 11 includes a front housing 111 and a rear housing 112 fastened to each other, the mounting grooves 114 are aligned in the front housing 111, and the bottom wall of each mounting groove 114 is located at the bottom wall of the front housing 111. This structure can reduce the mounting structure of the diaphragm sound generating device 12. The rear housing 112 may be integral with the ear mount.

Specifically, the main housing 11 includes an inner side plate and a sound output plate 1111, and when the earphone head 10 is worn on a human body, the inner side plate is attached to the face of the human body, and the sound output plate 1111 faces the auricle of the human body; each directional sound guide port 113 is located on the sound outlet plate 1111, the sound guide plate 1112 is located on the outer side surface of the sound outlet plate 1111, the sound guide plate 1112 is located on the edge of the directional sound guide port 113 far from the inner side plate and protrudes from the surface of the directional sound guide port 113, and part of the sound emitted from the directional sound guide port 113 in the direction far from the auricle is reflected in the direction of the auricle by the sound guide plate 1112. The sound guide plate 1112 may have a wave shape corresponding to the distribution of the directional sound guide ports 113. The sound entering the ear is increased by the sound guide plate 1112, reducing sound leakage from the earpiece 10.

In addition, in order to reduce the thickness and weight of the earphone head 10, the inner side plate and the outer side plate of the main housing 11 (i.e. the side plate of the main housing 11 opposite to the inner side plate) may respectively have a wave shape corresponding to the shape of the vibrating diaphragm sound generating device 12 in the main housing 11.

In combination with fig. 4, the present invention further provides a wireless earphone, which comprises a wearing member and two earphone heads 10 as described above, wherein the wearing member comprises two free ends, and the two earphone heads 10 are respectively fixed on one of the free ends of the wearing member.

Wherein control box 32 is used for holding control circuit board, accumulate unit etc. (the component that holds can be the same or different in two control boxes), and ear-hang 33 then can laminate the person's of wearing ear outer wall to realize hanging of earphone head 10 and wear, earphone head 10 need not excessively to extrude the person's of wearing face, reduces the uncomfortable sense that causes the person of wearing, also is convenient for wireless earphone and wears for a long time.

As shown in fig. 5-6 and 8-10, which are schematic structural diagrams of an earphone head 20 according to another embodiment of the present invention, similar to the embodiment of fig. 1-3, the earphone head 20 includes a main housing and two vibrating diaphragm sound-generating devices 22, wherein the vibrating diaphragm sound-generating devices 22 are installed in the main housing, and can convert electrical signals into sound to be played, in practical applications, the vibrating diaphragm sound-generating devices 22 may be speakers, and the number of the vibrating diaphragm sound-generating devices 22 may exceed two, for example, three, four, etc., without limitation.

In this embodiment, each vibrating diaphragm sound-generating device 22 has a sound-generating surface 221, the main housing has two directional sound-guiding ports 214, and the earphone head 20 is worn on the human body in such a manner that the two directional sound-guiding ports 214 face towards the auricles of the human body. Correspondingly, two mounting grooves 217 are formed in the main shell, the shape and the size of each mounting groove 217 are matched with those of the vibrating diaphragm sound-generating devices 22, the two vibrating diaphragm sound-generating devices 22 are respectively mounted in the two mounting grooves 217, and an internal sound cavity 25 is formed between the sound-generating surface 221 of each vibrating diaphragm sound-generating device 22 and the bottom wall of the corresponding mounting groove 217; the two internal sound cavities 25 are independent of each other, and each internal sound cavity 25 is communicated with the outside through a directional sound leading port 214. When the number of the diaphragm sound-emitting devices 22 in the earphone head is changed, the number of the directional sound-guiding ports 214 and the number of the mounting grooves 217 also need to be adjusted accordingly, i.e. the number of the directional sound-guiding ports 214 and the number of the mounting grooves 217 are the same as the number of the diaphragm sound-emitting devices 22.

The above-mentioned earphone head 20 can be worn by the suspension arm near the ear of the user without being inserted into the ear canal or pressing the auricle of the wearer from the front, but only by attaching the main housing to the face of the human body and directing the sound-guiding opening 214 toward the auricle, so that the sound emitted from the sound-emitting surface 221 of the diaphragm sound-emitting device 22 is transmitted to the auricle through the internal sound cavity 25 and the directing sound-guiding opening 214, and the sound is transmitted to the ear canal after being reflected by the auricle.

Preferably, the main housing in this embodiment includes an inner side plate 211, an outer side plate 212, and an annular side plate 213, the annular side plate 213 is located between the inner side plate 211 and the outer side plate 212 and is connected to the inner side plate 211 and the outer side plate 212, respectively, and the inner side plate 211, the outer side plate 212, and the annular side plate 213 enclose to form an accommodating cavity, and the mounting groove 217 is located in the accommodating cavity. The inner plate 211, the outer plate 212, and the annular side plate 213 are only named from the perspective of position, and may be the same component or different components. The diaphragm sound-generating device 22 has a sound-generating surface 221, and the diaphragm sound-generating device 22 is installed in the mounting groove 217 in such a manner that the sound-generating surface 221 faces the inner side plate 211, and an inner sound cavity 25 is formed by a cavity between the sound-generating surface 221 and the inner side plate 211.

In an embodiment of the present invention, the inner side plate 211 may be integrated with the annular side plate 213 and form the bottom shell as shown in fig. 9, that is, the annular side plate 213 may be formed by vertically extending the inner side plate 211 towards the outer side plate 212; the outer panel 212 alone forms a cover that snaps into place on the bottom housing, as shown in FIG. 10. Of course, in practical applications, the annular side plate 213 may be formed in other manners. In order to improve wearing comfort, arc-shaped surface transition can be respectively arranged between the inner side plate 211 and the annular side plate 213 and between the outer side plate 212 and the annular side plate 213.

The two directional sound guiding ports 214 are both located on the annular side plate 213 and are communicated with the internal sound cavity 25, that is, the directional sound guiding ports 214 are located between the inner side plate 211 and the outer side plate 212, and the earphone head is worn on the human body in a manner that the inner side plate 211 is attached to the face of the human body.

Because the sound emitting surface 221 of the diaphragm sound emitting device 22 is relatively large, in order to reduce the size of the main housing and ensure the sound playing quality, the diaphragm sound emitting device 22 is installed in the installation groove 217 in a manner that the sound emitting surface 221 inclines toward the surface where the directional sound guiding port 214 is located. That is, in the main housing, the sound emitting surface 221 of the diaphragm sound emitting device 22 faces the inner side plate as a whole and is inclined toward the directional sound guide port 214 (the included angle between the sound emitting surface 221 of the diaphragm sound emitting device 22 and the inner side plate 211 is an acute angle), for example, the included angle between the sound emitting surface 221 of the diaphragm sound emitting device 22 and the inner side plate 211 may be not less than 10 °, so that the sound emitted by the diaphragm sound emitting device 22 can be more directly transmitted from the directional sound guide port 214.

In an embodiment of the present invention, a sound reflection cone may be disposed in the internal sound cavity 25 of the main housing of the earphone head 20, and specifically, the sound reflection cone may be located on the surface of the inner side plate 211 facing the sound emitting surface 221 of the diaphragm sound emitting device 22 (i.e., the sound emitting surface of the diaphragm sound emitting device 22). Thus, the sound emitted from the diaphragm sound-generating device 22 is directly transmitted to the conical surface of the sound reflection cone, and the sound reflection cone emits the sound to the periphery, so that the sound emitted from the diaphragm sound-generating device 22 is emitted in the internal sound cavity 25, and the stereoscopic impression of the sound emitted from the diaphragm sound-generating device 22 is greatly improved. In particular, the central axis of the sound reflection cone is located on the same line as the central axis of the sound emitting surface 221 of the diaphragm sound emitting device 22.

As shown in fig. 7, in an embodiment of the present invention, an edge of each directional sound guiding port 214 away from the inner side plate 211 has a sound guiding plate 2131 protruding from a surface where an outlet of the directional sound guiding port 214 is located, and part of the sound coming out from the directional sound guiding port 214 in a direction away from the auricle is reflected toward the auricle by the sound guiding plate 2131. Due to the sound guide plate 2131, part of the sound coming out from the directional sound guide port 214 and going away from the auricle can be reflected by the sound guide plate 2131 towards the auricle, so that the sound leakage of the earphone head can be reduced, and the sound playing effect of the earphone head, especially the bass effect, can be improved. Specifically, the annular side plate 213 may have a recess adjacent to the inner side plate 211, i.e., one side of the recess extends to the inner side plate 211, the outlet of the directional sound guide port 214 is located at the bottom of the recess, and the sound guide plate 2131 is formed by the side wall of the recess. In particular, the sound guide plate 2131 may be located on the same plane as the sound emission surface 221 or parallel to the plane on which the sound emission surface 221 is located.

Preferably, the inner side plate 211 and the outer side plate 212 are parallel to each other, and each mounting groove 217 is located on the inner wall of the inner side plate 211. To reduce the overall thickness of the main housing, the inner wall of the outer plate 212 may have two recesses 2123, the outer wall of the outer plate 212 may have corresponding protrusions 2122, and at least a portion of a side of each diaphragm sound-generating device 22 facing away from the sound-generating surface 221 is fitted into the recess 2123 when the diaphragm sound-generating device 22 is fixed to the mounting groove 217. In addition, in order to prevent the diaphragm sound generating device 22 from generating abnormal sound due to the contact between the side of the diaphragm sound generating device 22 opposite to the sound generating surface 221 and the outer plate 212, a flexible buffer pad may be added to the side of the diaphragm sound generating device 22 opposite to the sound generating surface 221.

To facilitate the transmission of the sound emitted by the two directional sound guiding ports 214 into the ear, the annular side plate 213 may comprise a vertical plane perpendicular to the inner side plate 211, and the two directional sound guiding ports 214 are located on the vertical plane. While the centers of the two directional sound guide ports 214 may lie in a transverse plane parallel to the inner side plate 211.

Specifically, the inner side plate 211 and the outer side plate 212 may be rectangular to facilitate the installation of the diaphragm sound generating device 22 in the main housing, and of course, in practical applications, the shapes of the inner side plate 211 and the outer side plate 212 may also be adjusted according to the overall aesthetic feeling, and the like, and are not limited herein.

In one embodiment of the present invention, the inner wall of inner side plate 211 has two protruding ring baffles 2171, and each ring baffle 2171 is provided with a mounting step 2172, and each mounting groove 217 is formed by one ring baffle 2171 and a mounting step 2172. The diaphragm sound-generating device 22 is mounted in the mounting groove 217 by attaching the edge of the front end face to the mounting step 2172, and specifically, the diaphragm sound-generating device 22 and the mounting step can be fixed by gluing.

In addition, an external sound cavity 26 may be formed between the side of the diaphragm sound generating device 22 facing away from the sound generating surface 221 and the outer plate 212, and correspondingly, the outer plate 212 has a pressure relief hole 2121 communicating with the external sound cavity 26. The airflow generated by the vibration of the vibration sound generating device 22 can be oscillated in the external sound cavity 26 through the external sound cavity 26 and the pressure release holes 2121, and the pressure difference between the inside and the outside can be balanced through the pressure release holes 2121, so that the sound effect of the internal sound cavity 25 and the directional sound guide port 214, especially the effect of the bass part, can be greatly improved.
