Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth headsets, in particular to a capacitive in-ear detection TWS Bluetooth headset. Background Art

[0002] TWS earphones belong to the category of Bluetooth earphones. The main difference is true wireless and charging method. TWS Bluetooth earphones do not require wired connection, getting rid of the wired constraints of ordinary Bluetooth earphones. TWS earphones support wireless charging and charging box power supply, while Bluetooth earphones refer to audio equipment with built-in TWS earphone Bluetooth chip and replacing traditional wire connection with Bluetooth connection. Bluetooth earphones apply Bluetooth technology to traditional digital and multimedia audio, allowing users to avoid the entanglement of annoying wires and listen to music in various ways freely. The audio is connected to Bluetooth playback devices such as mobile phones, tablets or notebooks to achieve convenience and speed. At present, Bluetooth earphones are mainly portable speakers, and their appearance is generally small and portable. Bluetooth earphone technology has gradually been valued and accepted by consumers for its convenience. Most common Bluetooth earphones on the market are mono speakers, and some multi-channel speakers with excellent sound quality have also emerged.

[0003] Prior art, such as the patent with publication number CN216700268U, discloses a capacitive in-ear detection TWS Bluetooth headset, including a Bluetooth headset body, a speaker installed on one side of the Bluetooth headset body, in-ear detection parts are respectively provided on both sides of the surface of the speaker, and a detection unit is provided inside the Bluetooth headset body, and the detection unit is composed of a power supply unit, a chip unit, a capacitive detection unit and an in-ear detection unit. In the above scheme, when the user holds the Bluetooth headset body and pulls the speaker out of the user's ear in reverse, the capacitive detection unit sends the operation of pulling the speaker out of the user's ear through I2C communication, and the chip unit pauses the playback action, and adds a capacitive in-ear detection circuit to the TWS Bluetooth headset. When the user takes off the headset, the playback is stopped, and the headset detects that it is worn and plays normally. In this way, the power management of the headset can be effectively optimized and unnecessary power waste can be reduced, thereby effectively extending the battery life and enhancing the consumer experience.

[0004] The above prior art has obvious beneficial effects, but still has shortcomings:

[0005] In the above-mentioned prior art, a capacitance detection unit and an in-ear detection unit are placed inside the TWS Bluetooth headset, and the capacitive in-ear detection circuit inside the capacitance detection unit is used to detect the user's ear insertion and removal and control the playback, thereby reducing power waste. However, the earphone body is designed to be large in size, and it is easy for the earphone to fall off or shift in the ear during wearing, which affects the capacitance detection and causes misjudgment, resulting in a poor experience. For this reason, a capacitive in-ear detection TWS Bluetooth headset is proposed. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a capacitive in-ear detection TWS Bluetooth headset, which forms an elastic support after being inserted into the ear through the combination of the ear hook frame and the in-ear pile, thereby reducing the loosening and detachment phenomenon after being inserted into the ear. The ear hook frame at the top of the earphone frame forms an inside and outside positioning method, which improves the wearing stability and is convenient for use with capacitive in-ear detection.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a capacitive in-ear detection TWS Bluetooth headset, comprising an earphone main body, a bottom end of one side of the earphone main body is connected to an in-ear end, and a top end of the earphone main body is connected to an ear hanging frame, the in-ear end comprises an in-ear post, and one end of the in-ear post is connected to the earphone main body, the other end of the in-ear post is connected to a speaker, and an in-ear detection section is arranged around the speaker, the outer wall of the in-ear post is fitted with an earmuff, and the inner wall of the earmuff is filled with a rubber ring, a conical opening is opened on one side of the inner wall of the rubber ring, and a bracket is connected to the inside of the conical opening, and one end of the bracket is connected to a torsion spring frame.

[0008] Preferably, the tapered opening is opened in a ring shape along the inner wall of one side of the rubber ring, and the torsion spring frames are arranged equidistantly around the inner wall of the tapered opening.

[0009] Preferably, the outer walls of the in-ear pile are in close contact with the earmuff, and the in-ear pile is fixedly connected to the in-ear detection section and the speaker.

[0010] Preferably, the earphone body includes an earphone frame, and a Bluetooth module is arranged on one side of the inner wall of the earphone frame, and a connecting frame is arranged on the other side of the inner wall of the earphone frame, one end of the connecting frame is connected to an ear pile, and soft rubber rings are connected around the connecting frame.

[0011] Preferably, the soft rubber ring and the connecting frame are connected to the earphone frame, and the earplug post and the connecting frame are fixedly connected.

[0012] Preferably, the ear hanging frame comprises an arc frame, and the bottom surface of the arc frame is in contact with the earphone body, the top surface of the arc frame is connected to armature rods on both sides, and one end of the armature rod is connected to a hanging ring.

[0013] Preferably, the arm is connected to the arc frame and the hanging ring, and the arc frame is fixedly connected to the earphone body.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. During the earmuff insertion process, the earmuff is adaptively reduced by the conical mouth design and the internal torsion spring frame due to the size of the ear of the user. When the earmuff is inserted into the ear of the user, the rubber ring inside the earmuff is elastically expanded under the influence of the torsion spring frame, thereby providing expansion support to the inside of the ear without affecting the wearer's comfort, thereby reducing the wearing instability caused by loose earmuffs and affecting the capacitive in-ear detection.

[0016] 2. This Bluetooth headset maintains an integrated connection with the in-ear post through a connecting frame. When the in-ear post is worn in the ear, it can be adaptively adjusted through the soft rubber ring connected around the connecting frame, which is convenient for matching with different cochlear shapes of users and is convenient and comfortable to wear.

[0017] 3. The top of the earphone is equipped with a hanging ring to provide auxiliary support for the overall wearing of the earphone, further improving the overall wearing stability of the earphone.

[0018] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model.

[0026] like Figure 1-3 As shown, the Bluetooth headset in the utility model is similar to the existing Bluetooth headset structure, such as a capacitive in-ear detection TWS Bluetooth headset with publication number CN216700268U. The main improvement of the utility model is that the ear hook frame 3 is combined with the earmuff 204 of the in-ear pile 201 to form an elastic support after use, reduce the loosening and detachment phenomenon after entering the ear, and cooperate with the ear hook frame 3 at the top of the earphone frame 101 to form an inside and outside positioning method, improve the wearing stability, and facilitate the use of capacitive in-ear detection; the in-ear detection section 203 and the Bluetooth module 102 in the utility model are both prior arts. When using this Bluetooth headset, the connecting frame 103 can be used to maintain an integral connection with the in-ear pile 201. When the in-ear pile 201 is worn in the ear, it can be adaptively adjusted through the soft rubber ring 104 connected around the connecting frame 103, which is convenient for matching with different cochlear shapes of users, and is convenient and comfortable to wear. After wearing, the Bluetooth module 102 is connected to the speaker 202 in the in-ear pile 201 for music playback.
