Embodiment Construction

[0023] Figure 5 is a cross-sectional view of a receiving unit of a terminal device according to an embodiment of the present invention. The receiving unit includes a main body 6 having an outer shell 2 and an inner shell 4 connected to the outer shell 2 . The main body 6 also includes a liquid crystal screen and a microphone (both are not shown). Also, the receiver 8 is installed inside the main body 6 to generate sound, and the sound emitting hole 10 is formed on the inner case 4 to release the sound generated by the receiver 8 to the outside. A sound leakage unit is installed between the receiver 8 and the inner case 4 for leaking part of the sound generated from the receiver 8 . The terminal device of the present invention is applicable to any of a variety of terminals, including but not limited to mobile terminals, wired terminals, wireless terminals or any other electronic equipment containing a receiver or sound generator.

[0024] The receiver 8 includes an upper ca...

Abstract

An electronic device includes a sound generator, a housing having a plurality of holes, and a sound controller between the sound generator and housing. The sound controller controls discharge of sound from the sound generator through the holes in the housing. The discharge of sound is preferably controlled based on a predetermined sound leakage pattern. The sound controller includes a leakage member having a plurality of holes arranged based on the sound leakage pattern. The leakage member may be arranged so that some of the holes are coincident with sound holes in a casing of the devices, while other holes are not in alignment with the casing holes. As a result, sound leakage is generated which substantially reduces sound volume differences when the electronic device is used at varying distances from a user. The electronic device may, for example, be a mobile terminal.

Description

technical field [0001] The present invention relates to a terminal device, more specifically, to a receiving unit of a terminal device with volume output control. Background technique [0002] A terminal device generally includes a printed circuit board (PCB) inserted into a main body, operation buttons for performing various functions, a microphone for inputting a user's voice, a receiving unit for a user to receive voice, and a device for displaying various information. LCD screen. [0003] figure 1 shows a front view of the terminal, and figure 2 is a partial sectional view showing the assembly of a conventional receiving unit. In these figures, the terminal main body 106 includes: an outer shell 102 and an inner shell 104, a receiving unit 108 inserted into the main body 106 to generate sound, one or more sound emitting holes penetrating the inner shell and releasing the sound generated by the receiving unit 110, and a seal 112 installed between the front of the rec...
