Abstract
Description
Technical field:
[0001] The present invention relates to the technical field of earphones, and in particular to an in-ear sports earphone that meets the requirements of high power, waterproofness, and stable wearing of the sports earphone. Background technology:
[0002] Existing headphones can be generally divided into in-ear headphones, semi-in-ear headphones and open-ear headphones according to the sound transmission method. For in-ear headphones, a silicone ear cap is usually set at the sound outlet, and the ear cap is adapted to the position of the human ear canal, so that the sound emitted by the headphone is directly transmitted to the ear canal.
[0003] At present, sports headphones are developed for consumers who love sports. According to market feedback, the main demands of consumers for such sports headphones are:
[0004] 1. The earphones are stable to wear and not easy to fall off during running and other sports;
[0005] 2. The battery capacity of the headset is large enough to meet the long-term outdoor battery life;
[0006] 3. The waterproof performance of the earphones is good enough;
[0007] 4. Clear calls can be achieved during exercise.
[0008] Based on the above requirements, current sports headphones mostly use head-mounted, ear-hook and other structures. Traditional headphones with a ball-hammer shape of the head and stem are not suitable for sports headphones. This is because in-ear headphones are mainly worn by the ear cap and the ear canal. During exercise, the swing of the stem will cause the headphones to fall off. In addition, the internal space of such headphones is limited and is not suitable for setting up a large-capacity battery pack. At the same time, the head and stem of such headphones usually require multiple shells to be assembled, and the shells have more joint surfaces, so it is difficult to achieve a higher level of waterproof performance.

[0039] The present invention is further described below in conjunction with specific embodiments and drawings.
[0040] The present invention is an in-ear sports earphone. Figures 1 to 8 As shown, this embodiment includes: a shell 1a and a circuit board assembly 4, a speaker 5, a battery pack 6 arranged in an inner cavity 10 of the shell, and a silicone ear cap 3 connected to the shell 1a.
[0041] Combination Figure 1 As shown, the shell 1a is in the shape of a ball hammer with a head 11a and a rod 12a, wherein the head 11a is roughly in the shape of a sphere with a smooth surface, the rod 12a is roughly in the shape of a cylinder or a quasi-cylindrical body, and there is a smooth transition between the head 11a and the rod 12a.
[0042] A hollow mouthpiece 11 is provided at the front end of the head 11a, which is away from the central axis of the stem 12a. The sound produced by the earphone is emitted from the outlet of the mouthpiece 11 and is transmitted to the human ear canal after passing through the silicone ear cap 3.
[0043] Combination Figure 3 , Figure 4As shown, the housing 1a is composed of a front housing 1 and a rear housing 2 that are buckled together. The entire housing 1a of the present invention is directly formed by the front housing 1 and the rear housing 2 being buckled together, and the joint surface between the front housing 1 and the rear housing 2 is located on the same plane. The structure of the joint surface is simple, and it is relatively simple to set the waterproofing, and a better waterproofing effect can be achieved later. Specifically, the front housing 1 and the rear housing 2 are combined in the following manner: an outer step portion 16 and an inner step portion 26 that match each other are formed on the edges where the front housing 1 and the rear housing 2 are butted together. A raised sealing strip 160 is formed on the outer side wall of the outer step portion 16, and a sealing groove 260 that matches the sealing strip 160 is formed on the inner side wall of the inner step portion 26. When the front housing 1 and the rear housing 2 are butted together, the outer step portion 16 and the inner step portion 26 are mutually clamped together, and the combination between the sealing strip 160 and the sealing groove 260 not only plays the role of clamping and fixing, but also has a good waterproofing effect.
[0044] Furthermore, since the housing 1a of the conventional earphone is made of plastic material, its strength is not high, and the housing 1a of the present invention has a certain length as a whole, it is inevitable to deform when held by external force. When the outer step portion 16 and the inner step portion 26 are mutually clamped and matched, the outer wall of the inner outer step portion 16 may bend and deform inwardly under the action of external force, resulting in waterproof failure. In order to avoid this situation, the method adopted by the present invention is as follows: a plurality of reinforcing blocks 25 are arranged on the inner wall of the rear housing 2 near the inner step portion 26, and when the front housing 1 and the rear housing 2 are assembled, the reinforcing blocks 25 are located on the inner side of the outer wall of the outer step portion 16 to prevent the inner side of the outer wall of the outer step portion 16 from deforming inwardly.
[0045] In addition, in addition to the use of the outer step portion 16 and the inner step portion 26 on the front shell 1 and the rear shell 2 that cooperate with each other to achieve docking, the present invention also provides a plurality of pin hole components between the two to achieve alignment and reinforcement.
[0046] The front end surface of the front housing 1 extends downwardly and integrally to form a hollow sound mouth portion 11, and the silicone ear cap 3 is detachably connected to the sound mouth portion 11. The sound mouth portion 11 is located at the head 11a. Specifically, the sound mouth portion 11 includes: an extension portion 12, a neck portion 13 and a flange portion 14, wherein the extension portion 12 extends from the front end surface of the front housing 1 and is in the shape of an inverted bell mouth that gradually shrinks.
[0047] The speaker 5 is located in the extension cavity 120 in the extension part 12, and the space in the mouthpiece 11 is isolated from the cavity 10 by the speaker 5, wherein the space between the front end of the speaker 5 and the flange 14 constitutes the front sound cavity, and the space between the rear end of the speaker 5 and the cavity 10 constitutes the rear sound cavity.
[0048] The speaker 5 in the present invention is not placed directly in the main body cavity of the head 11a, but the mouthpiece 11 is extended outward to form an extension cavity 120, and the speaker 5 is placed in the extension cavity 120. Since the extension cavity 120 has limited space, the present invention can use a smaller dynamic speaker.
[0049] Since the speaker 5 is placed in the extension cavity 120, the main premise space in the head 11a is large enough, and the space for placing the battery pack 6 will also be larger, so that a larger capacity battery pack can be placed, thereby providing the headset with longer battery life.
[0050] In order to obtain better sound quality, it is necessary to set tuning holes in the front and rear sound cavities of the earphone. In the present invention, the neck 13 of the mouthpiece 11 is in the shape of an annular groove, and a front tuning hole 130 and a groove 131 connected to the front tuning hole 130 are provided at the neck 13. The front sound cavity is connected to the external space through the front tuning hole 130 and the groove 131.
[0051] The silicone ear cap 3 includes: an integrally formed outer layer 31 and a tube portion 32 formed with a channel 30, the front end of the tube portion 32 is connected to the front end of the outer layer 3, and the inner wall of the channel 30 at the rear end of the tube portion 32 is formed with an inner flange 320 that is snap-fitted with the neck 13.
[0052] In order to prevent the inner flange 320 of the silicone ear cap 3 from blocking the front tuning hole 130, the groove 131 extends along the neck 13 toward the side of the extension part 12, and the groove 131 extends all the way to the circumferential side surface of the end of the extension part 12, so that the front tuning hole 130 can be connected with the external space through the groove 131.
[0053] The length of the outer layer 3 is greater than that of the tube portion 32 , and the front sound cavity is connected to the space enclosed by the outer layer 31 through the front tuning hole 130 and the groove 131 , so that the front tuning hole 130 can be shielded.
[0054] See Figure 8 As shown, the silicone ear cap 3 in the present invention is replaceable, and the user can choose silicone ear caps of different sizes according to their needs. In order to facilitate the connection of the silicone ear cap 3 to the neck 13, the rear end of the tube 32 of the silicone ear cap 3 is formed with a chamfer. When replacing, the elasticity of the silicone ear cap 3 is utilized to sleeve the tube 32 on the neck 13, and the neck 13 is fixed by nesting with the inner flange 320.
[0055] The front housing 1 is provided with a rear tuning hole 17 near the sound outlet 11, and the rear tuning hole 17 is connected to the rear sound cavity. Figure 8 As shown, the rear sound cavity in the present invention is mainly the space between the battery pack 6 and the speaker 5.
[0056] The circuit board assembly 4 includes: a circuit board 41, and a sound receiving microphone 42, a charging electrode 43, a light emitting LED 44 and a sensing electrode sheet 55 connected to the circuit board 41. The shape of the circuit board assembly 4 corresponds to the cross section of the inner cavity 10 of the shell 1a, and the circuit board 41 extends from the space of the head 11a to the space of the rod 12a. The sound receiving microphone 42, the charging electrode 43, and the light emitting LED 44 are located in the space of the rod 12a, and the sensing electrode sheet 55 is attached to the inner wall of the rear shell 2 in the head 11a and is connected to the circuit board 41. The battery pack 6 is located in the space of the head 11a and between the circuit board 41 and the speaker 5.
[0057] The electrode sheet 52 is attached to the inner wall of the rear shell 2. When the user touches the outer surface of the rear shell 2, an induction signal is generated to trigger the earphone to generate a response instruction, such as adjusting the earphone volume.
[0058] A sound receiving hole 15 is provided on the bottom surface of the rod portion 12a near the mouthpiece portion 11. In this way, the sound receiving hole 15 can be as close to the user's mouth as possible to obtain a clearer call quality. A sound receiving cavity 150 is provided inside the front housing 1 at a position corresponding to the sound receiving microphone 42, and the sound receiving hole 15 extends inward until it is connected to the sound receiving cavity 150. During a call, the sound emitted by the user will enter the sound receiving cavity 150 through the sound receiving hole 15 and be transmitted to the sound receiving microphone 52.
[0059] A thin-walled portion 23 is formed on the inner surface of the rod portion 12a at the position of the rear shell 2, and a light guide block 7 is provided on the thin-walled portion 23. A light guide hole 70 is provided on the guide block 7. The light-emitting LED 44 on the circuit board 41 corresponds to the position of the light guide hole 70. The light generated by the light-emitting LED 44 passes through the light guide hole 70 and irradiates the thin-walled portion 23, and is transmitted from the surface of the rear shell 2.
[0060] The light guide hole 70 in the light guide block 7 has a larger aperture near the light-emitting LED 44 to correspond to multiple light-emitting LEDs 44 of different colors. By switching different light-emitting LEDs 44, the surface of the rear shell 2 transmits light of different colors.
[0061] In order to fix the light guide block 7, a positioning hole 71 is opened on the light guide block 7, and a positioning pin 24 is formed on the inner wall of the rear shell 2 to cooperate with the positioning hole 71. The positioning hole 71 cooperates with the positioning pin 24 to achieve the positioning connection of the light guide block 7.
[0062] The present invention aims to improve the angle setting between the head 11a and the rod 12a, by collecting consumer data and combining Figures 9 to 11As shown, the angle α between the central axis of the mouthpiece 11 and the central axis of the rod 12a of the present invention is 55° to 65°, and the angle β at which the central axis of the mouthpiece 11 deviates from the horizontal center line of the rod 12a is 22° to 28°.
[0063] Combination Fig.11 As shown, after adopting this design, when the user wears the earphones of the present invention, the head 11a is located in the concha cavity 91 of the ear 9, and the silicone ear cap 3 is inserted into the ear canal. At this time, the stem 12a is just located in the area between the middle tragus 92 and the outer tragus 93 of the human ear. The stem 12a is clamped by the tragus 92 and the outer tragus 93, so that the earphones are worn more firmly and are not easy to fall off during exercise.
[0064] In addition, since the speaker 5 is arranged in the mouthpiece 11 and the battery pack 6 is located between the circuit board 41 and the speaker 5, the center of gravity of the headphone can be shifted to the ear canal as much as possible, which can further increase the stability of wearing the earphone.
[0065] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
