Description

Adjustable sound headphones

The present invention relates to an earphone, and more particularly to an adjustable earphone.

According to the continuous advancement of technology, electronic products with music playback functions are also updated faster, such as MP3 players and mobile phones. In order to allow consumers to listen to the sound of electronic products without interference from outsiders and without disturbing others, headphones have become an essential accessory for electronic products.
With the improvement of living standards, consumers' demand for hearing has also increased accordingly. However, there are differences in the structural dimensions of each person's ear and ear canal, and each person's preference for sound is often different. The earphones produced by major manufacturers are often fixed structures, and the sound effects can not be adjusted, so it is difficult to meet the individual needs of consumers.
At present, there is a type of earphone on the market. As shown in the first figure, the earphone 100' includes a casing 10' and a sounding device 20'. The sounding device 20' is disposed in the casing 10' and between the casing 10'. A resonant cavity 21' is formed, and the casing 10' is provided with a tuning hole 113' communicating with the resonant cavity 21'. In order to adjust the low-frequency sound emitted by the pronunciation device 20' to change the frequency difference between the high-pitched sound and the low-frequency to generate different musical feelings, generally, the damping chamber 30' is placed or not placed in the resonant cavity 21' to the resonant cavity. The pressure within 21' is controlled (illustrated to place the damper 30' in the resonant cavity 21'), thereby changing the damping effect of the utterance device 20', thereby changing the frequency difference between the treble and the bass to produce different sounds. effect.
However, since the damper 30' is placed in the resonant cavity 21', the consumer cannot replace the damper 30' as desired to enjoy more musical effects. That is to say, once the consumer buys such a headset 100', it can only accept the music effect brought by the headset 100'. Therefore, the earphone 100' cannot meet the personality needs of the consumer.

The purpose of this creation is to provide a tunable earphone that can easily change the tuning device in view of the drawbacks and deficiencies of the prior art.
In order to achieve the above object, the present invention comprises a casing, a sounding device and a tuning device, and a tuning hole is arranged at the rear of the casing; the sounding device is installed inside the casing and forms a resonant cavity with the casing. The tunable device is rotatably mounted on the rear of the casing, and has a vent hole penetrating through the front and rear surfaces of the tuning device. The vent hole is in communication with the tuning hole, and a damping object is integrally formed on the front surface of the tuning device.
As described above, the present adjustable sound earphone has a tuning hole formed in the rear of the casing, and the rear part of the casing is rotatably provided with a tuning device integrally formed with the damping object, and the tuning device has a through-the-surface through the front and rear surfaces of the tuning device. The air hole is replaced by a tuning device with different damping materials, so that the adjustable earphone has different tuning effects.

To clarify the technical content, structural features, objectives, and effects of the present invention, the embodiments are described in detail below with reference to the drawings.
Referring to the second and third figures, the present tunable earphone 100 includes a housing 10, a sounding device 20 and a tuning device 30.
Referring to the third, fourth and fifth figures, a tuning hole 113 is defined in the rear of the housing 10. The housing 10 includes a bass housing 11 and a tweeter housing 12 that is capped with the bass housing 11. An annular inner extending portion 111 is formed in the rear portion of the bass housing 11 , and a closed rear wall 112 is defined in the middle of the inner side wall of the extending portion 111 . The tuning hole 113 is defined in the rear wall 112 . An annular snap portion 114 is protruded from the inner side of the rear surface of the extending portion 111. The front portion of the outer surface of the latching portion 114 defines an annular latching groove 115. The latching portion 114 defines two front and rear surfaces of the through latching portion 114. The guide slot 116.
The sounding device 20 is mounted inside the casing 10 and forms a resonant cavity 21 with the casing 10. The sounding device 20 forms a low-pitched cavity 211 with the bass housing 11, and a high-pitched cavity 212 is formed between the sounding device 20 and the tweeter housing 12.
Referring to the second to fifth figures, the tuning device 30 is rotatably mounted on the rear of the casing 10, and has a cylindrical shape with a front small rear and a large shape, and a vent hole 36 extending through the front and rear surfaces of the tuning device 30 is defined therein. The vent hole 36 is in communication with the tuning hole 113, and a damping material 37 is integrally formed on the front surface of the tuning device 30. The tuning device 30 has a cylindrical base portion 31 which is small in front and large, and a cylindrical main body portion 32 is protruded forwardly in the middle of the base portion 31. The base portion 31 protrudes forwardly from the outer side of the main body portion 32 by a length smaller than that of the main body portion. The annular cover plate 33 and the inner side wall of the cover plate 33 are provided with two stoppers 34. The cover plate 33 and the main body portion 32 form an annular groove 35. The vent hole 36 extends through the base portion 31 and the main body portion 32. The damper 37 is integrally formed on the front surface of the main body portion 32. The stopper 34 is rotatably inserted into the annular slot 115 via the guide slot 116. The main body portion 32 of the tuning device 30 is mounted in the latching portion 114. The damper 37 is attached to the rear wall 112, the latching portion 114 is locked in the slot 35, and the cover plate 33 is disposed outside the latching portion 114.
When the sounding device 20 of the presently tunable earphone 100 vibrates, the pressure in the resonant cavity 21 changes, and at the same time, the pressure of the bass inner cavity 211 also changes, and the tuning hole 113 is opened in the bass housing 11. And the vent hole 36 that communicates with the tuning hole 113, so that the bass inner cavity 211 communicates with the external space, and the external airflow will enter the treble inner cavity 212 and the low-pitched cavity 211 through the vent hole 36 and the tuning hole 113 to facilitate the adjustment of the resonance. The air pressure in the cavity 21, in turn, achieves the effect of tuning, and the setting of the damper 37 can assist in adjusting the pressure in the bass chamber 211. When the user is not satisfied with the tuning effect of the tuning device 30 of the adjustable-tone earphone 100, by integrally molding the different damping objects 37 on the tuning device 30, it is only necessary to replace the tuning device 30 in which the different damping objects 37 are integrally formed.
As described above, the present adjustable-tone headphone 100 has a tuning hole 113 formed in the rear of the bass housing 11, and the rear portion of the bass housing 11 is rotatably coupled to the tuning device 30 integrally formed with the damping object 37, and the tuning device 30 is mounted on the tuning device 30. A vent hole 36 is formed through the front and rear surfaces of the tuning device 30, and the tuning device 30 having different dampers 37 are integrally formed, thereby making the tunable earphone 100 have different tuning effects.
