Description

Technical Field

[0001] The utility model relates to the technical field of audio equipment, in particular to an ear-clip type earphone. Background Art

[0002] Open-ear headphones are mainly divided into hanging earphones and clip-on earphones. Among them, hanging earphones will not fit tightly against the ears, reducing the pressure on the ear canal, but they are large in size and are likely to affect the comfort of the ears after long-term wearing. As a more emerging product, clip-on earphones are compact and lightweight in overall structure, and clamped on the auricle to reduce the pressure on the ears, which largely makes up for the shortcomings of hanging earphones. Clip-on earphones usually include a speaker close to the wearer's ear canal and a balance module placed on the back of the ear. The speaker and the balance module are connected by an arm beam, and the arm beam provides a clamping force so that the speaker and the balance module can be clamped and attached to the wearer's auricle. However, there are still areas that need to be improved in the use of current clip-on earphones. For example, clip-on earphones generally adopt the form of a single-arm beam, which is difficult to obtain force compensation during the clamping process and is prone to excessive deformation, which leads to the risk of loosening.

[0028] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0029] See also Figure 1 The present invention provides an ear-clip earphone, comprising a first ear-clip portion 100, a second ear-clip portion 200 and a connecting portion 300; wherein the first ear-clip portion 100 has a built-in speaker 110 (see Figure 4 ); The connecting portion 300 connects the first clamping ear portion 100 and the second clamping ear portion 200.

[0030] See also Figure 2 The connecting portion 300 includes a first arm beam 310 and a second arm beam 320 arranged side by side, and the first arm beam 310 and the second arm beam 320 are respectively bent and extended in the direction from the first ear clamping portion 100 to the second ear clamping portion 200; in the wearing state, the first ear clamping portion 100 is located in the ear cavity, the second ear clamping portion 200 is located at the back side of the ear, and the first ear clamping portion 100 and the second ear clamping portion 200 jointly clamp the ear.

[0031] The current clip-on earphones basically adopt a single arm beam design, that is, a single arm beam is used to connect the two end parts of the earphone. During the insertion and wearing process, the arm beam needs to bear a large external tension. The single structure will make the arm beam thin, and the arm beam is easy to plastically deform due to excessive force, which increases the opening of the clip-on earphone, making it difficult to clamp and easy to fall off, which greatly affects the user's experience of using the clip-on earphone. In this regard, the embodiment of the present application sets a first arm beam 310 and a second arm beam 320 side by side between the first ear clamping part 100 and the second ear clamping part 200, so as to form an ear clip structure in the form of a double arm beam. The double arm beam can realize mutual compensation of clamping force in the wearing state, achieve better elastic deformation ability, and maintain a relatively stable clamping performance even in the case of long-term or over-open use, which is conducive to maintaining the original shape of the ear clip and can improve the stability of wearing.

[0032] Specifically, see Figure 1 and Figure 2 The first clamping ear portion 100 and the second clamping ear portion 200 are placed flat on the reference plane A, and the first arm beam 310 and the second arm beam 320 are arranged at intervals along the direction perpendicular to the reference plane A, thereby forming a double-arm beam structure that is easy to hold and squeeze.

[0033] According to the operation habits of the general public, when putting on or removing the earphone, people usually bend the second ear clip part 200 facing the back of the ear outward to open the connecting part 300, and ensure that the opening of the connecting part 300 is larger than the thickness of the auricle before putting the earphone on the auricle or removing the earphone from the auricle. In this process, the tension on the second ear clip part 200 and the connecting part 300 close to the second ear clip part 200 is obviously greater than the force on other parts such as the first ear clip part 100. In order to prevent the connecting part from being pulled, deformed or broken at the position close to the second ear clip part 200, it is very necessary to establish a more stable structure at this position; for this, please refer to Figure 2 Along the direction from the first ear portion 100 to the second ear portion 200, the first arm beam 310 and the second arm beam 320 gradually approach each other. By arranging the first arm beam 310 and the second arm beam 320 to approach or even aggregate in the area close to the second ear portion 200, the tensile strength of the area of ​​the connecting portion 300 close to the second ear portion 200 can be improved, thereby significantly reducing the risk of deformation of the earphone.

[0034] As an ear-clamping structure, the connecting part 300 needs to have a certain degree of elasticity, so the first arm beam 310 and the second arm beam 320 are both elastic parts. Specifically, the first arm beam 310 and the second arm beam 320 are made of silicone and have a strip structure, which can achieve a lightweight structure while also obtaining good flexible deformation and rebound capabilities.

[0035] See also Figure 3 , a first channel 311 is provided inside the first arm beam 310, and the extension path of the first channel 311 is the same as the extension path of the first arm beam 310. A first steel wire 312 is passed through the first channel 311. The steel wire has good tensile strength and compressive strength, can withstand large external forces, and can resist excessive deformation of the earphone to a certain extent, which is conducive to maintaining the original shape of the ear clip. Similarly, a second channel 321 is provided inside the second arm beam 320, and the extension path of the second channel 321 is the same as the extension path of the second arm beam 320. A second steel wire 322 is passed through the second channel 321. Both the first arm beam 310 and the second arm beam 320 are in the form of a combination of silicone soft body and steel wire, which can use silicone to achieve skin-friendly comfort while enhancing the clamping toughness of the connection part 300.

[0036] A battery 210 and corresponding electronic components are arranged in the second ear-clip portion 200. Thus, the electrical components mainly including the battery 210 and the sound-generating components mainly including the speaker 110 are arranged on both sides of the connecting portion 300, which can achieve weight balance of the ear-clip earphones and reduce unstable wearing caused by excessive weight on one side.

[0037] See also Figure 4 and Figure 5 The first ear-clip part 100 includes an earphone front shell 100A and an earphone rear shell 100B. The front shell 100A and the earphone rear shell 100B are buckled together to form a sound cavity 120 for placing a speaker 110. The speaker 110 divides the sound cavity 120 into a front sound cavity 121 and a rear sound cavity 122. An earphone sound outlet hole 130 is provided on the cavity wall of the front sound cavity 121. The front sound cavity 121 is connected to the external space of the first ear-clip part 100 through the earphone sound outlet hole 130. The earphone sound outlet hole 130 is sequentially covered with a front cavity tuning net 140 and a front cavity dustproof net 150; a tuning hole 160 is provided on the cavity wall of the rear sound cavity 122. A tuning hole 160 is covered with a tuning dustproof net 170. The tuning dustproof net 170 can prevent dust from entering the sound cavity 120, which helps to extend the service life of the earphone.

[0038] Since the ear-clip earphones adopt an open wearing method in which the speaker is far away from the ear canal, the ear-clip earphones often have a certain low-frequency loss. In this regard, some existing ear-clip earphones are equipped with a bass reflex tube to enhance the bass range. The bass reflex tube is arranged at the rear sound outlet position of the speaker, and the sound outlet end of the bass reflex tube is arranged on the side away from the earphone sound outlet. However, such an arrangement will make the sound outlet end of the bass reflex tube easily blocked by the ear during wearing, thereby affecting the enhancement effect of the heavy bass sound waves.

[0039] As one of the ways to solve the above-mentioned problem, the sound outlet end of the bass reflex tube should be set as close to the arm beam as possible or on the arm beam, so as to smoothly guide the sound waves behind the speaker outward. However, for single-arm earphones, this method is not easy to achieve. The inside of the single-arm beam itself needs to be threaded with wires to power the earphones. Once a bass reflex sound outlet is set on the single-arm beam, due to the very compact space of the earphones, the bass reflex sound outlet must be connected to the wiring trough for placing the wires. External dust can easily fall into the wiring trough through the bass reflex sound outlet, thereby polluting the internal environment of the earphones and causing obvious damage to the overall sound quality.

[0040] See also Figure 4, and the embodiment of the present application is provided with a first arm beam 310 and a second arm beam 320, thereby forming a double-arm beam connection structure, wherein the first arm beam 310 is centrally arranged and connects the first clamping ear portion 100 and the second clamping ear portion 200, and a wire 313 is arranged in the first arm beam 310, one end of the wire 313 is connected to the speaker 110, and the other end is connected to the battery 210. On this basis, the embodiment of the present application is provided with an inverted tube (not shown in the figure) in the rear sound cavity 122, the sound input end of the inverted tube is close to the speaker 110, and the sound output end of the inverted tube is extended in a direction close to the connection portion 300 and away from the rear sound cavity 120, and the sound output end of the inverted tube can be arranged in an area away from the sound cavity 120 to ensure that the sound output end of the inverted tube is not blocked. Specifically, the second arm beam 320 is provided with an inverted channel inside, one end of the inverted channel is connected to the rear sound cavity 122, and the other end is connected to the surface of the second arm beam 320 away from the first ear clamping part 100 to form an inverted sound outlet 400. The sound outlet end of the inverted tube passes through the inverted channel and is inserted in the inverted sound outlet 400. The sound waves entering the inverted tube will enter the human ear through the inverted sound outlet 400. In this structure, the sound outlet end of the inverted tube is exposed on the surface of the second arm beam 320 away from the earphone sound outlet 130. In the wearing state, this surface of the second arm beam 320 will not contact the ear, ensuring that the sound outlet end of the inverted tube will not be blocked by the human ear. By providing the inverted tube, the low-frequency sound waves reflected by the rear sound cavity 122 can be better exported, avoiding the monotonous interference of the sound caused by the lack of bass in the sound effect.

[0041] In this structure, the speaker 110 is located between the headphone sound outlet 130 and the bass reflex tube. When the speaker 110 plays sound, the front sound waves are transmitted through the headphone sound outlet 130, and the rear sound waves are transmitted outward through the bass reflex tube, so that the vibration behind the speaker 110 is also utilized. Finally, the rear sound waves transmitted outward are strengthened, that is, the heavy bass is strengthened, thereby improving the bass sound quality of the headphone.

[0042] In addition, the inverted sound outlet 400 can also be arranged on the wall of the rear sound cavity 122 close to the connecting portion 300, especially on the wall of the rear sound cavity 122 away from the earphone sound outlet 130. The sound outlet of the inverted tube is inserted into the inverted sound outlet 400. When worn, the wall of the rear sound cavity 122 has little or no contact with the human ear, which can also prevent the inverted tube from being shielded. It can be understood that any method of setting the sound outlet of the inverted tube away from the human ear can be applied to the present technical solution, so the present invention does not impose a mandatory limit on the position of the sound outlet of the inverted tube.

[0043] Regardless of the setting of the bass reflex sound outlet position, the diameters of the bass reflex sound outlet hole 400 and the bass reflex tube are smaller than the diameter of the speaker 110, to ensure that the sound waves of the rear sound cavity 122 can rush out, and the sound waves of the front sound cavity 121 and the rear sound cavity 122 are fully utilized, so that the low-frequency sound quality of the clip-on earphones is effectively improved, thereby improving the common low-frequency deficiency of open-ear headphones.

[0044] Furthermore, the diameters of the inverted sound outlet 400 and the inverted tube are equal, and such an arrangement can reduce the reflection attenuation of the sound waves in the inverted link, thereby reducing distortion and improving sound quality.

[0045] In general, the embodiment of the present application provides a first arm beam 310 and a second arm beam 320 to form a double-arm beam connection structure, thereby providing a more stable clamping force, which is beneficial to improving the wearing stability and service life of the earphone; among them, the first arm beam 310 of the embodiment of the present application is also used for the routing of electrical circuits, and the second arm beam 320 is provided with a bass reflex sound outlet hole 400, so that the bass reflex tube and the wiring groove are separated from each other, preventing dust and dirt from entering the wiring groove and even other internal environments of the earphone from the bass reflex sound outlet hole 400, thereby maintaining the cleanliness of the inside of the earphone.

[0046] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
