Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-3, an embodiment of the present invention discloses an in-ear bluetooth earphone, which includes a speaker 1 and an earphone body 2 having a speaker cavity 2021, the exterior of the earphone body 2 is further provided with a sound outlet 3 communicated with the speaker cavity 2021, a convex ring 2022 for limiting the speaker 1 is disposed in the speaker cavity 2021 in front of the outlet of the sound outlet 3, the speaker 1 is fixed in the convex ring 2022; a sealed front sound cavity 2023 is formed between the loudspeaker 1 and the sound outlet 3, and the front sound cavity 2023 is communicated with the sound outlet 3.

In the utility model, under the condition of satisfying the ergonomics, the horn 1 is separated from the sound outlet 3 by adding the front sound cavity 2023; when the consumer took this embodiment bluetooth headset, because loudspeaker 1 has the certain distance apart from going out mouthpiece 3 when, consequently loudspeaker 1 among this embodiment bluetooth headset is farther apart from the ear than the loudspeaker in current bluetooth headset, loudspeaker 1's size just no longer too much receives the restriction of external auditory canal size this moment, then just can install the loudspeaker of bigger diameter in loudspeaker cavity 2021 to increase bluetooth headset's frequency response width, and then make bluetooth headset's low and high frequency tone quality abundanter.

In this embodiment, the front sound cavity 2023 is tapered to meet the ergonomic requirement; in addition, the sound outlet nozzle 3 is positioned at one end of the front sound cavity 2023 and forms an included angle of more than 100 degrees with the loudspeaker 1. If the horn is too far away from the sound outlet 3, the sound emitted from the sound outlet 3 is small, so that the user experience is influenced; therefore, in the present embodiment, the front sound cavity 2023 is designed to be conical, and the sound outlet 3 is disposed at one end of the front sound cavity 2023, so that the sound outlet 3 is close to the speaker 1, thereby avoiding the sound emitted by the sound outlet 3 being small due to the existence of the front sound cavity 2023; the sound outlet 3 and the horn 1 form an included angle larger than 100 degrees, which is also based on the requirement of human engineering, and meanwhile, the sound outlet 3 can be closer to the horn 1.

Further, the earphone body 2 comprises a body 201 and a shell 202 for fixing the loudspeaker 1, wherein the left side of the shell 202 is curved towards the right side of the shell 202, so that the shape of the shell 202 forms a conical shape with the tail end biased towards one side of the shell 202; the mouthpiece 3 is attached to the tapered end of the housing 202. In this embodiment, the shape of the casing 202 is designed to be a cone, the cone end is biased to one side of the casing 202, and the sound outlet 3 is connected to the cone end of the casing 202, so as to meet the requirement of human engineering, and ensure that no discomfort is caused when the user wears the bluetooth headset of this embodiment.

Of course, the body 201 further includes the necessary components and parts of bluetooth headset such as power, circuit board, microphone, and these belong to prior art, the utility model discloses no longer describe herein.

Further, the front sound cavity 2023 is provided with a tuning hole 2024. In this embodiment, while the size of the speaker 1 is increased, the front sound cavity 2023 may generate an echo effect on the vibration of the speaker 1, and the sound quality effect of the bluetooth headset may be further improved; and in the process of loudspeaker 1 vibration, atmospheric pressure can form in the preceding sound chamber 2023, can let bluetooth headset's tone quality effect more ideal through the regulation of tuning hole 2024 to atmospheric pressure this moment.

The utility model discloses in, through above design, can install the loudspeaker that the diameter is not less than 12mm for bluetooth headset's frequency response width can reach 100Hz-16KHzHz, makes bluetooth headset's low and high frequency tone quality abundanter.

Further, this embodiment in-ear bluetooth headset still includes earmuff 4, and earmuff 4 cover is established on sound outlet 3, and is identical with the external auditory canal of ear, more does benefit to protection bluetooth headset.
