    • Provided is an air conditioner. According to the air conditioner, an installation structure of an indoor heat exchanger installed inside the air conditioner is improved, so that the air conditioner become slim and an installation space for additional devices such as a filter can be secured. According to the air conditioner, the indoor heat exchanger divides a passage of air introduced into a main unit into an upper passage and a lower passage, so that interference between the upper and lower passages can be minimized, and thus operation efficiency of the air conditioner can improve. Also, a space of a predetermined size is formed between the indoor heat exchanger and air intake holes to receive a predetermined device such as a filter and a negative ion generator that can give a separate function to the air conditioner.
    • 提供一种空调。 根据空调机,设置在空调机内部的室内热交换器的安装结构得到改善,使得空调变得苗条,并且可以确保用于诸如过滤器的附加装置的安装空间。 根据空调机,室内热交换器将引入主单元的空气的通道分成上通道和下通道,从而可以使上通道和下通道之间的干扰最小化,从而空调器的运行效率 可以改善 此外,在室内热交换器和进气孔之间形成预定尺寸的空间,以接收能够向空调机分配功能的诸如过滤器和负离子发生器的预定装置。

    • The present invention relates to a protective case for preventing damage to a mobile terminal, comprising: an actuator (12) comprising a piezoelectric vibrating screen (17) formed by attaching a piezoelectric element layer (20) to at least one side of a substrate (18), at least one or more weight pieces (22) which are fixedly attached to the piezoelectric element layer (20) and increase the vibration force, and a bracket (24) provided so that both ends of the substrate (18) are fixedly attached thereto; an auxiliary battery (10) which supplies power to the actuator (12) and is used for charging in the case where a battery of a mobile terminal (4) is discharged or consumed; and a Bluetooth receiving module (30) for receiving a signal transmitted from a Bluetooth transmitting module (28) of the mobile terminal (4). As the actuator (12), which provides real-time vibration feedback, is installed in the inner side of the protective case (2)(2a) which is worn for preventing damage to the mobile terminal (4), the protective case has an effect of giving a user simultaneous sensory stimulation by providing the user with a haptic signal corresponding to an image and sound outputted from the mobile terminal (4) as a rapid vibration response. In addition, the protective case can transfer various vibration patterns including strong vibration and micro vibration as the vibration amount of the actuator (12) is adjusted according to the magnitude of vibration, or a vibration motor (14) is controlled so as to provide vibration feedback at low frequency, and thus, the protective case has an effect of giving the user a sense of realism.
