    • The present invention relates to a non-directional speaker, and more particularly, to a non-directional speaker which smoothly outputs non-directional sound without sound distortion and which is inexpensive. To this endFor this purpose, the non-directional speaker includescomprises: a case defining a receiving space therein, the case having a sound transmitting area in an the upper portion thereof; a cover body disposed on the upper portion of the said case; and a speaker received in the receiving space of the said case, the speaker being coupled to the said sound transmitting area so that the direction in which sound is discharged is oriented toward a the bottom surface of the said cover body. The Said cover body refracts the direction in which sound outputted by said speaker proceeds that is output from the speaker into separated spaces between the cover body and the case.
    • 本发明涉及一种非定向扬声器,更具体地说,涉及一种平滑地输出无声音失真且便宜的非定向声音的非定向扬声器。 为此目的,无方向性扬声器包括:限定其中的接收空间的壳体,该壳体在其上部具有声音传播区域; 设置在所述壳体的上部的盖体; 以及扬声器,其被容纳在所述壳体的接收空间中,所述扬声器耦合到所述声音传播区域,使得声音被排出的方向朝向所述盖体的底面。 所述盖体将从扬声器输出的所述扬声器输出的声音的方向折射到盖体和壳体之间的分隔空间。

    • The present invention relates to an electronic locker with a variable secret code input unit. Compared with an existing touch screen related technique that has an input unit randomizing the number display positions to prevent the exposure risk of secret codes caused by fingerprint marks, the invention more specifically concerns the electronic locker that includes a secret code input unit with at least two input sets where input elements indicating the combination of numbers or/and characters are fixedly arranged. More desirably, the input elements indicate some or all numbers from 0 or 1 to 9. When an input signal is applied to the locker, a microcontroller enables a light source for the input elements in all or some input sets to emit light in order to select an actual input set that is configured in the combination of numbers or/and characters, more desirably in the combination of all or some numbers from 0 or 1 to 9. Therefore, the invention is able to not only prevent the exposure risk of secret codes but also minimize power consumption. In addition, the invention is convenient for the input of secret codes.
    • 本发明涉及一种具有可变密码输入单元的电子储物柜。 与现有的触摸屏相关技术相比,具有使数字显示位置随机化的输入单元以防止由指纹标记引起的密码的曝光风险,本发明更具体地涉及包括具有至少两个的密码输入单元的电子储物柜 输入集合,其中指示数字或/和字符的组合的输入元素被固定地布置。 更理想地,输入元件指示从0或1到9的一些或所有数字。当输入信号被施加到储物柜时,微控制器使得所有或某些输入组中的输入元件的光源能够发光,以便 选择以数字或/和字符组合配置的实际输入集合,更理想的是从0或1到9的全部或部分数字的组合。因此,本发明不仅可以防止秘密的曝光风险 代码,同时也降低功耗。 此外,本发明方便输入密码。
