可调音耳机adjustable earphones

技术领域technical field

本实用新型涉及一种耳机，尤其涉及一种可调音耳机。The utility model relates to an earphone, in particular to an adjustable tone earphone.

背景技术Background technique

随着科技不断进步，电子产品也在更新换代，为了让使用者在不干扰旁人的状况下聆听电子产品发出的声音，耳机已成为电子产品的必要配件。如图1所示，传统的耳机100′包括壳体10′、发声装置12′及阻尼物14′，发声装置12′设置于壳体10′内，并与壳体10′之间形成一共振腔(图未示)。壳体10′包括低音壳体101′及与低音壳体101′盖合在一起的高音壳体102′。所述发声装置12′与高音壳体102′间形成耳机高音内腔11′，所述发声装置12′与耳机高音壳体102′以及低音壳体101′围成耳机低音内腔13′。为了对发声装置12′发出的低频段声音进行调整以利于低频段声音与高频段声音匹配，通常在低音壳体101′内的一端固定不同的阻尼物14′，利用不同材质的阻尼物14′对发声装置12′发出的低频段声音进行调整，以与高频段声音匹配，从而使得声音好听，起到调音的效果。With the continuous advancement of technology, electronic products are also being updated. In order to allow users to listen to the sound from electronic products without disturbing others, earphones have become a necessary accessory for electronic products. As shown in Figure 1, a traditional earphone 100' includes a housing 10', a sounding device 12' and a damper 14', and the sounding device 12' is arranged in the housing 10' and forms a resonance with the housing 10' cavity (not shown). The casing 10' includes a bass casing 101' and a tweeter casing 102' covered together with the bass casing 101'. The earphone treble inner chamber 11' is formed between the sound generating device 12' and the treble housing 102', and the earphone bass inner chamber 13' is surrounded by the sound generating device 12', the earphone treble housing 102' and the bass housing 101'. In order to adjust the low-frequency sound emitted by the sounding device 12' to facilitate the matching of the low-frequency sound and the high-frequency sound, usually a different damper 14' is fixed at one end of the bass housing 101', and the damper 14' of different materials is used. The low-frequency sound emitted by the sound-generating device 12' is adjusted to match the high-frequency sound, thereby making the sound pleasant and achieving the effect of tuning.

但是，众所周知，每个人的耳朵、耳道结构的尺寸都有差异，每个人对音乐的喜好也往往不同，而上述耳机100′的阻尼物14′固定于低音壳体101′内，无法随心所欲的更换，消费者一旦买了这样的耳机，就只能接受该耳机所带来的音乐效果，无法对发出的声音效果进行调整，难以满足人们的个性需求。But, as we all know, the size of each person's ear and ear canal structure is different, and each person's preferences for music are also often different, and the damper 14' of the above-mentioned earphone 100' is fixed in the bass shell 101', so it cannot be played freely. Replacement, once consumers buy such earphones, they can only accept the music effects brought by the earphones, and cannot adjust the sound effects sent, which is difficult to meet people's individual needs.

This figure intercepts the reflection of the sound when thetuning hole 11 of the utility model is in different shielding states in the frequency range (20HZ～20KHZ) of human hearing. As shown in the figure, when the shieldingbody 511 is aligned with the two tuningholes 11 of thebass shell 10, and thegap 513 is aligned with the other two tuningholes 11, an appropriate change in air flow will be caused to achieve low-frequency volume. As a result of the change, the frequency response curve of the bass is shown by the curve I in the figure. At this time, the damping body 5 is not placed at thetuning hole 11; The twotuning holes 11 of thebody 10 are aligned, and when thegap 513 is aligned with the other two tuningholes 11, the frequency response curve of the bass is shown by curve II in the figure; the dampingbody 52 is blocked in the tuning holes Atposition 11, when the shieldingbody 511 is not aligned with thetuning hole 11, that is, when the shieldingbody 511 covers all the tuning holes 11, the frequency response curve of the bass is shown by curve III in the figure. It can be seen from the graph that thetuning device 50 is provided on thebass shell 10 of the utility model, so that the low frequency can have different sound performances and the low frequency is more delicate while ensuring that the high frequency is prominent.

如上所述，本实用新型可调音耳机通过旋动调音装置50的连杆512带动遮蔽体511同步旋转，从而遮蔽体511可调整的遮挡全部或部分所述调音孔11，而且调音孔11处挡设所述阻尼体52，辅助调整耳机低音内腔内的压力，所以可使本实用新型可调音耳机低频可以有不同的低频声音表现，从而可以更好地满足不同使用者的需求。As mentioned above, the adjustable earphone of the present invention drives the shieldingbody 511 to rotate synchronously by rotating the connectingrod 512 of thetuning device 50, so that the shieldingbody 511 can be adjusted to shield all or part of thetuning hole 11, and the tuning The dampingbody 52 is blocked at thehole 11 to assist in adjusting the pressure in the bass inner cavity of the earphone, so that the low frequency of the adjustable tone earphone of the present invention can have different low frequency sound performances, thereby better satisfying the requirements of different users. need.

但是，以上实施例仅用以说明本实用新型商务原理，由连杆512旋转带动遮蔽体511进行位移调整而遮挡调音孔11。实际制造时，依据调音孔11数量、形状、大小等的不同，遮蔽体511随之变化增减，且遮蔽体511的具体形态可以是挡板结构，挡块结构或者其它形状结构，遮蔽体511还可以呈圆环状，以整体遮蔽所有的调音孔11。However, the above embodiments are only used to illustrate the business principle of the utility model, and the connectingrod 512 rotates to drive the shieldingbody 511 to adjust the displacement to shield thetuning hole 11 .
