Embodiment Construction

[0030] Preferred embodiments of the present disclosure will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0031] The present disclosure provides a device for adjusting sound quality, which increases the cavity space of the sound cavity by increasing the dynamic sound cavity that can protrude from the fixed tone cavity, so as to achieve the purpose of improving the sound quality of the sound played.

[0032] like figure 1 As shown, it is a device for adjusting sound quality in an embodiment of the present disclosure, and the device includes:

[0033] Loudspeaker 102 and sound cavity 101;

[0034] Wherein, the sound chamber 101 includes: a fixed sound chamber 104 and a moving sound chamber 105;

[0035] A leak hole 103 is provided on one side of the sound chamber 105, an...

Abstract

The invention relates to a device for regulating the tone quality and terminal equipment. The device comprises a loudspeaker and sound cavity, wherein the sound cavity comprises a fixed sound cavity and a mobile sound cavity; the loudspeaker is located in the fixed sound cavity; a side surface of the mobile sound cavity is provided with a leakage hole, the internal part of the mobile sound cavity is communicated with the external part of the device through the leakage hole, other parts, except for the leakage hole, of the sound cavities are sealed; a side, which is opposite to the leakage hole, of the mobile sound cavity is not provided with the side wall, and the side without the side wall faces toward the loudspeaker. When the volume of the sound cavity does not need to be expanded, cavity bodies of the mobile sound cavity and the fixed sound cavity are overlapped, and when the volume of the sound cavity needs to be expanded, the mobile sound cavity moves relative to the fixed sound cavity, at least part of the mobile sound cavity is located outside the fixed sound cavity. The fixed sound cavity is provided with an opening in the side wall at the moving direction of the mobile sound cavity, and the size of the opening is consistent with the outer diameter of the mobile sound cavity. The device provided by the invention increases the volume of the sound cavity through additionally arranging the mobile sound cavity, thereby improving the tone quality of sound.

Description

technical field [0001] The present disclosure relates to the technical field of sound playback, and in particular, to a device for adjusting sound quality and a terminal device. Background technique [0002] The sound cavity refers to the cavity that collects the sound within a certain range and then emits the sound through a point. For example, when a person speaks, the mouth and brain cavity are a kind of sound cavity. issue. However, when smart terminals widely enter people's lives, smart terminals have an indispensable function, that is, the playback function. Whether it is audio, video or incoming ringtones, they all need to be played through the speaker, and the speaker needs to be equipped with a sound cavity to achieve a good effect. The size of the sound cavity here has a great influence on the sound quality of the ringtone and the receiver. The sound quality of the same sound source and the same speaker in different sound chambers varies greatly, some are more pl...
