Description

Electronic device

Technical Field

The application relates to the technical field of loudspeaker structure setting of electronic equipment, in particular to electronic equipment.

Background

Under the development trend of a full-screen electronic device (such as a mobile phone and the like), a sound outlet of a receiver continuously moves towards a frame, the call sound leakage is more serious than that of a non-full-screen electronic device, and the privacy becomes a remarkable user pain point along with the attention of a user to the call privacy. In order to reduce call leakage and meet the requirement of call privacy, the common practice in the industry is to reduce the maximum loudness of a receiver, which sacrifices the acoustic quality to a certain extent. The solution with more innovation and quality assurance is to construct a sound field with directivity (i.e. a receiver sound field), which is also a commonly accepted idea in the industry. But is affected by the wavelength of the sound wave, and the realization difficulty is larger.

A related technology adopts the idea of frequency division compensation to reduce call leakage, namely a combination form of moving coil SPK (medium and low frequency, auditory sense compensation) + piezoelectric SPK (medium and high frequency, master sound), on one hand, the piezoelectric driving unit is arranged below a screen to push the screen to vibrate and sound, and a sound source is relatively centered and generates a sound field with certain directivity; on the other hand, the piezoelectric SPK low-frequency loss is made up through the moving coil SPK, so that relatively balanced hearing is achieved. The scheme gives consideration to the visual requirement of a comprehensive screen and the function requirement of reducing call sound leakage, but the scheme of combining the multiple types of devices has higher cost and has certain requirement on the posture of holding the mobile phone by a user. Other related technologies adopt a dipole sound field scheme to improve the mobile phone call privacy, which is mainly to form a single dipole sound field by a pair of dipole sound sources, but the cancellation area of the sound field is narrow (i.e. the privacy protection area is narrow).

Specifically, the electronic device 10 includes a housing 20, a first speaker 30, and a second speaker 40.

The housing 20 has a first surface 201, a second surface 202 adjacent to the first surface 201, a first sound outlet hole 211 disposed on the first surface 201, a second sound outlet hole 212 disposed on the second surface 202, a third sound outlet hole 213 disposed on the second surface 202, a first sound outlet channel 221 disposed inside the housing 20 and communicated with the first sound outlet hole 211, a second sound outlet channel 222 disposed inside the housing 20 and communicated with the second sound outlet hole 212, and a third sound outlet channel 223 disposed inside the housing 20 and communicated with the third sound outlet hole 213.

The first speaker 30 is disposed inside the casing 20 and corresponds to an end of the first sound emitting channel 221 away from the first sound emitting hole 211.

As shown in fig. 2 and fig. 3, in the present embodiment, the number of the second speakers 40 is two, and the two second speakers 40 are disposed in the casing interior 20 and respectively correspond to an end of the second sound emitting channel 222 away from the second sound emitting hole 212 and an end of the third sound emitting channel 223 away from the second sound emitting hole 212. The phases of the sound waves emitted by the two second speakers 40 may be the same and opposite to the phases of the sound waves emitted by the first speakers 30. Specifically, the sound wave emitted from the second sound outlet 212 and the sound wave emitted from the third sound outlet 213 have the same phase and the opposite phase to the sound wave emitted from the first sound outlet 211, so that the sound wave emitted from the second sound outlet 212 and the sound wave emitted from the first sound outlet 211 may form a dipole sound field, and the sound wave emitted from the third sound outlet 213 and the sound wave emitted from the first sound outlet 211 may form another dipole sound field.

However, as shown in fig. 4, in a modified embodiment, the number of the second speakers 40 may also be one, the second speakers 40 may be disposed in the middle area inside the casing 20, and an end of the second sound emitting channel 222 away from the second sound emitting hole 212 may communicate with an end of the third sound emitting channel 223 away from the third sound emitting hole, so that the second speakers 40 may correspond to an end of the second sound emitting channel 222 away from the second sound emitting hole 212 and an end of the third sound emitting channel 223 away from the third sound emitting hole 213 at the same time. The phase of the sound wave emitted from the second speaker 40 is opposite to the phase of the sound wave emitted from the first speaker 30, and further, the phase of the sound wave emitted from the second sound outlet 212 is the same as that of the sound wave emitted from the third sound outlet 213 and is opposite to that of the sound wave emitted from the first sound outlet 211, so that the sound wave emitted from the second sound outlet 212 and the sound wave emitted from the first sound outlet 211 can form a dipole sound field, and the sound wave emitted from the third sound outlet 213 and the sound wave emitted from the first sound outlet 211 can form another dipole sound field.

The sound wave emitted by the second sound outlet hole 212 and the sound wave emitted by the first sound outlet hole 211 can form a dipole sound field, the sound wave emitted by the third sound outlet hole 213 and the sound wave emitted by the first sound outlet hole 211 can form another dipole sound field, the electronic device 10 is not only simple in structure and low in cost, but also the two dipole sound fields have large sound field cancellation areas, so that the area of the privacy protection area can be increased, and the conversation privacy of the electronic device 10 can be improved. In addition, the layout of the first speaker 30 and the two second speakers 40 not only meets the requirement of the call privacy function, but also meets the hardware requirement of the multi-speaker (stereo) outward-playing, so that one device has multiple purposes, the cost is further reduced, the sound effect is improved, and the user experience is higher.

It can be understood that the first sound outlet hole 211, the second sound outlet hole 212 and the third sound outlet hole 213 are arranged in a staggered manner, which is beneficial to reducing the thickness of the electronic device 10 along the direction from the first surface 201 to the third surface 203, and is further beneficial to thinning the electronic device 10, and improving the user experience and the product competitiveness.
