An ear-hook headphone

Technical Field

The utility model relates to an ear-hook type earphone.

Background technique

Earhook headphones refer to headphones that have auxiliary hanging decorations added to the side of the headphones for ease of use. Earhook headphones are mainly composed of two parts: the host and the earhook. The host is set in a casing, which generally contains the headphone circuit board, speaker and battery, etc. The earhook fixes the host casing to the auricle so that the speaker mouth is opposite to the external auditory canal, and the sound played is transmitted to the eardrum through the external auditory canal.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 is an exploded view of the earhook and the host housing of the earhook type earphone in Embodiment 1 of the present invention.

Detailed ways

As shown in FIG1 , this embodiment is an ear-hook type earphone, which is a Bluetooth earphone, comprising an earphone housing 100 containing an earphone body, and an earhook 200 fixing the earphone housing 100 to the auricle; in this embodiment, the earhook 200 and the earphone housing 100 are connected to each other by a mortise and tenon connection. The earphone body mainly comprises a circuit board, a speaker and a rechargeable battery. In fact, this embodiment can be a Bluetooth earphone, and an audio unit is arranged on the earphone circuit board, and the audio unit comprises a signal receiving module and a power amplifier module; in practice, the signal receiving module can receive an audio signal or a high-frequency modulated signal, such as a digital audio signal transmitted to the earphone circuit board through a Bluetooth communication module, and the digital audio signal is received on the circuit board through the Bluetooth module and then decoded to form an audio signal, which is amplified by the power amplifier module and connected to the earphone speaker to play the audio signal. In fact, it can also be other wireless earphones, which use wireless communication to send the audio signal to the earphone, and then demodulate, decode, etc. to form an audio signal to be played by the earphone speaker.

Therefore, no matter what kind of headphones, a signal receiving module is needed, which can be a wireless receiving module or a wired signal receiving module. The signal receiving module is used to receive audio signals and transmit the audio signals to the power amplifier module; the power amplifier module is used to amplify the received audio signals and transmit them to the headphone speakers for playback.

In this embodiment, the ear hook 200 is made of silicone. In fact, the function of the ear hook 200 is to fix the earphone body including the housing for mounting the host circuit board, the battery and the speaker to the auricle, so that the horn on the earphone housing 100 is opposite to the external auditory canal, and the sound played is transmitted to the eardrum through the external auditory canal. In order to make the horn on the earphone housing 100 relatively tight with the external auditory canal, the ear hook 200 is made of silicone with good plasticity. In practice, in order to maintain the shape of the ear hook 200, a memory metal strip is implanted in the middle of the silicone of the ear hook 200. In this embodiment, the ear hook 200 is an arc-shaped silicone sleeve that can be hung on the auricle, including an elastic part 210 and a first bulge 220 and a second bulge 230 formed by the elastic part 210 extending to both ends. The first bulge 220, the elastic part 210 and the second bulge 230 form an arc-shaped ear hook 200, and a first interface 221 connected to the earphone housing 100 is formed at the outer end of the first bulge 220. Here, the ear hook 200 is small in the middle and large at both ends. The small middle portion is to facilitate the deformation of the elastic part 210 to match auricles of different sizes, and the large ends are to facilitate the setting of the first interface 221 on the first enlarged part 220. The second expansion part 230 forms a tail close to the auricle, so as not to make people uncomfortable when the auricle is squeezed.

In fact, the shape of the earphone housing 100 can be various, as long as the side close to the external auditory canal can have a side with a bell mouth 111. In this embodiment, the earphone housing 100 is a rectangular parallelepiped as a whole. When in use, the side close to the external auditory canal is called the inner side, and the side opposite to it is the outer side. The other four sides are the upper and lower sides and the left and right sides. In this embodiment, the inner side 100 has a bell mouth 111, and the side of the bell mouth 111 is provided with a second interface 112 connected to the ear hook 200. This second interface 112 corresponds to the first interface 221 on the ear hook 200. In practice, the second interface can be on the upper side or left and right sides of the earphone shell 100. At present, the ear hooks of many ear-hook earphones extend from the upper side of the earphone shell 100. Such earphones often need to be provided with a hard silicone or other hard material in the earphone shell 100 to fix the ear hook. In many cases, metal screws are used to fix the ear hook to the earphone shell 100, which increases the cost, generally up to 2 to 4 yuan. In this embodiment, the connection method of the mortise and tenon structure does not require metal screws, etc. It is only necessary to use silicone to form the mortise and tenon holes in the two interfaces when making the mold, and the cost is very low, only 0.5 yuan.

In this embodiment, a falcon head 112-1 is provided on the second interface 112, and a mortise 221-1 matching the falcon head 112-1 is provided on the first interface 221. In practice, the falcon head and the mortise may be interchanged, and the falcon head may be on the first interface 221 and the mortise may be on the second interface 112. However, since the outer wall of the earphone shell is generally thin, it is more appropriate to set the mortise on the ear hook.

In some embodiments, the ear hook 200 can rotate on the earphone housing 100, so the falcon head 112-1 includes a circular protrusion set in the center of the circular second interface 112, and the mortise 221-1 includes a circular pit set in the center of the circular first interface 221, and the inner diameter of the circular pit is consistent with the diameter of the circular protrusion. Sometimes, in order to adjust the direction of the ear hook, it is necessary to adjust the angle between the ear hook and the earphone housing, so the falcon mortise structure is rotatable in a symmetrical manner.

In this embodiment, the ear hook 200 and the earphone housing 100 are fixedly connected to each other. At this time, the falcon head 112-1 includes an elliptical protrusion arranged in the center of the circular second interface 112, and the mortise 221-1 includes an elliptical pit arranged in the center of the circular first interface 221, and the inner diameter of the elliptical pit is consistent with the diameter of the elliptical protrusion. Since the elliptical protrusion cannot rotate in the elliptical pit, the ear hook 200 cannot rotate with the earphone housing 100. At this time, in order to ensure that the two interfaces are more secure, glue can be used to bond the two interfaces together. In addition, in this embodiment, the falcon head 112-1 also includes a positioning column arranged on the side of the elliptical protrusion, and the mortise 221-1 also includes a positioning hole arranged on the side of the elliptical pit. When the second interface 112 is plugged into the first interface 221, the positioning column is inserted into the positioning hole.

In this embodiment, the space in the earphone housing 100 is divided into an independent speaker cavity and a battery cavity by a partition, the earphone speaker is a 15100 speaker, which is sealed and installed in the speaker cavity, and the 15100 speaker faces the speaker mouth 111. The earphone battery is a rechargeable battery, which is stacked in the battery cavity, and the earphone circuit board covers the outside of the speaker cavity and the battery cavity. The earphone speaker is installed with an independent sealing structure to form an independent cavity, which has better sound quality.

In this embodiment, a charging circuit for charging the earphone battery is provided on the circuit board, and a charging interface 113 is provided between the second interface 112 and the horn 111. The charging interface 113 is provided outside the earphone housing 100, so as to facilitate charging the earphone when it is placed in the earphone box.
