However, these embodiments are not intended to limit the present invention, and structural, methodical, or functional changes that may be made by one of ordinary skill in the art based on these embodiments are all included in the scope of the present invention.
The utility model provides an assist and listen earphone is applicable to the application scene that provides the hearing aid for the impaired user of hearing, can effectively solve current assist and listen earphone and set up the problem that can lead to the microphone to seriously whistle after in going out the sound pipe with the speaker.
Referring to fig. 1 to 3, in the present embodiment, the auxiliary listening earphone includes a composite earphone housing 1, a speaker 2, and a microphone 3. The composite earphone shell 1 comprises a shell body 101 formed by buckling a front shell 1011 and a rear shell 1012, a sound outlet pipe 102 used for extending into an ear canal, and a flexible connecting part 103 used for connecting the front shell 1011 and the sound outlet pipe 102.
The front shell 1011 and the rear shell 1012 are buckled to form an accommodating cavity 1013, a circuit board 4 is arranged in the accommodating cavity 1013, the circuit board 4 is electrically connected with the loudspeaker 2 and the microphone 3 respectively, and a storage battery 5 electrically connected with the circuit board 4 is further arranged in the accommodating cavity 1013 so as to supply power to the circuit board 4.
In this embodiment, the hardness of both the casing main body 101 and the sound outlet tube 102 is greater than the hardness of the flexible connection portion 103, for example, the flexible connection portion 103 is made of a soft rubber material such as silica gel or soft rubber, and the casing main body 101 and the sound outlet tube 102 are made of a hard rubber material such as hard plastic.
The speaker 2 is installed in the sound outlet tube 102 of the composite earphone housing 1, and the microphone 3 is installed on the housing main body 101.
It should be noted that, in the composite earphone casing 1 provided in this embodiment, the flexible connection portion 103 is disposed between the casing main body 101 and the sound outlet tube 102, when the speaker 2 vibrates and generates sound, most of the vibration will be absorbed by the flexible connection portion 103 after the vibration is transmitted to the flexible connection portion 103, and even if the rest of the vibration is transmitted to the microphone 3 through the casing main body 101, the vibration will not cause the microphone 3 to generate strong sound, so that the microphone 3 will not generate an obvious howling phenomenon. Therefore, the composite earphone shell 1 provided by this embodiment can not only set the speaker 2 in the sound outlet tube 102 to reduce the distance between the speaker 2 and the eardrum, but also effectively suppress the howling problem of the microphone 3, thereby effectively improving the user experience.
Optionally, the front shell 1011, the flexible connecting portion 103 and the sound outlet tube 102 are formed by two-shot injection molding so as to improve the connection reliability of the front shell 1011, the flexible connecting portion 103 and the sound outlet tube 102 and reduce the number of assembling processes.
In this embodiment, the exterior of the speaker 2 is sleeved with a damping rubber sleeve 6. The damping rubber sleeve 6 can absorb the vibration transmitted from the loudspeaker 2 to the sound outlet pipe 102, and further inhibit the squeal problem of the microphone 3. Optionally, the vibration damping rubber sleeve 6 is connected with the sound outlet pipe 102 in an interference fit manner, and the speaker 2 can be taken out of the sound outlet pipe 102 only by extending a tool such as a practical small push rod into the sound outlet pipe 102 and poking the speaker 2, so that the assembly and disassembly are convenient and fast.
Furthermore, a limiting boss 1021 is arranged at one end of the sound outlet pipe 102 close to the ear canal, so as to limit the vibration damping rubber sleeve 6 from penetrating through the sound outlet pipe 102. Therefore, when the speaker 2 needs to be detached, the front housing 1011 and the rear housing 1012 should be detached first, and then the speaker 2 in the sound tube 102 should be poked inward, so that the speaker 2 is poked out from the side of the sound tube 102 close to the front housing 1011, and then is separated from the sound tube 102.
In this embodiment, the sound insulation board 7 is disposed between the accommodating chamber 1013 and the sound outlet tube 102, air vibration caused by the sound generated by the speaker 2 may be transmitted to the microphone 3 along the accommodating chamber 1013 to cause a weak squeal problem, and after the sound insulation board 7 is disposed, the sound transmission between the sound outlet tube 102 and the housing main body 101 is blocked, so that the squeal problem of the microphone 3 is further suppressed.
Optionally, the loudspeaker 2 is a moving coil loudspeaker, so as to have a better auxiliary listening experience. The outside of the sound outlet tube 102 is sleeved with an ear cap to improve the comfort of the user when wearing the sound outlet tube.
The compound earphone casing that this embodiment provided and assist and listen the earphone possesses following advantage:
(1) the loudspeaker is arranged in the sound outlet pipe, so that the distance between the loudspeaker and the eardrum can be reduced to the maximum extent, and the hearing-aid effect is improved;
(2) the composite earphone shell with a soft-hard combined structure is adopted to block the vibration transmission between the sound outlet pipe and the shell body, so that the problem of microphone squeaking caused by the vibration transmission is solved;
(3) the sound-proof plate is used for separating the sound outlet pipe from the shell body, so that the microphone squeaking problem caused by sound wave transmission is avoided.
It should be understood that although the specification describes embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and it will be appreciated by those skilled in the art that the specification as a whole may be appropriately combined to form other embodiments as will be apparent to those skilled in the art.
The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.
