At least one tuning lamellar body, a side that deviates from described opening of letting out sound hole described in described tone tuning piece body is positioned at.
Like this sound in resonance cavity with the madial wall of housing, vibrating diaphragm and tuning lamellar body bump, reflection, thereby empathize to reach lifting tonequality, make the object that tonequality is submissiveer, and tuning lamellar body is according to design, the difference of demand, select unlike material and thickness, to reach required acoustic feature and the effect of kind, and the sender on fixed head of passing through of the sound after sympathetic response, lid is passed to soft cover body and listens to for user, and the pressure that sound-producing device produces because of vibration, shock wave releases adjusting sympathetic response from Vent sound hole via tuning lamellar body, uncomfortable to reduce user.
Further, in described resonance cavity, be provided with at least one sound-producing device.
Further, between the madial wall of described resonance cavity and described sound-producing device, leave spacing.
Further, the close described opening part of described housing is provided with at least one fixed head, and described fixed head is provided with a plurality of senders.
Further, a side that deviates from described housing of described fixed head is provided with at least one lid, and the described sender of the correspondence of described lid place is provided with the first through hole.
Further, a side that deviates from described fixed head of described lid is provided with at least one soft cover body, and the described sender of the correspondence of described soft cover body place is provided with the second through hole.
Further, described tuning lamellar body consists of the material with sympathetic response coefficient.
Further, described tuning lamellar body is ventilative tuning lamellar body.
The beneficial effects of the utility model are, by be provided with at least one resonance cavity in housing, and a side of housing is provided with the opening that at least one is connected with resonance cavity, and deviating from a side of opening, housing is provided with the sound hole of letting out that at least one is connected with resonance cavity, let out and in sound hole, be provided with at least one vibrating diaphragm, in a side that deviates from opening of letting out sound hole, be provided with at least one tuning lamellar body, between sound-producing device in housing and the madial wall of resonance cavity, leave spacing like this, sound-producing device is sounded via vibration, this sound is in resonance cavity and housing, vibrating diaphragm and tuning lamellar body bump, reflection, empathize, promoted tonequality, and tuning lamellar body can select unlike material to reach the effect of required tonequality kind according to design.The shock wave simultaneously producing because of sound-producing device vibration releases letting out after sound hole is adjusted sympathetic response via tuning lamellar body, can not attack user's ear directly, compared with prior art, for the conventional existing lower tone of all cover earphone, easily cause the problem of user's discomfort to be broken through, reached simple in structure, comfortable and improved the practical improvement of tonequality.
