Problems solved by technology

[0005] Aiming at the fact that the existing car audio system is difficult to achieve the same effect of listening to music as earphones at a low cost, and wearing earphones is not suitable for car drivers, the present invention provides an independent audio system for car seats. The headrest is modified to make it an independent near-field audio system, which can effectively reduce the loss and distortion of audio sound waves in the air, and has obvious stereo effects, thereby greatly improving the sound effect of listening to music in the car

Embodiment 1

[0019] Embodiment 1: as figure 1 As shown, a car seat audio independent system includes a headrest, a speaker, a power amplifier and a sound source. The power amplifier installed in the headrest a1 is connected to the speaker and the sound source respectively, and the headrest a1 is installed on the back of the car seat. The upper top of the headrest can be adjusted up and down. The headrest a1 includes the middle occipital part a1-1, and the left wing parts a1-2 and The right wing part a1-3, the left and right wing parts a1-2, a1-3 are provided with cavities for embedding sound boxes, the central axes of the left and right speakers a2, a3 of the sound boxes are respectively connected to the headrest a1 The intersecting angle of the central axis is θ, θ=60°~120° angle, the present embodiment selects θ=70°, the left loudspeaker a2 of the left wing part a1-2 and the right loudspeaker a3 of the right wing part a1-3 are respectively installed in the left, In the cavity of the inn...

Embodiment 2

[0020] Embodiment 2: as figure 2 and 3 As shown, a car seat independent audio system includes a headrest, a sound box, a power amplifier b8, a wireless transmission module b7 and a sound source b9, and the power amplifier b8 installed in the pillow b1 makes signals with the sound box and the sound source b9 respectively The headrest is installed on the upper top of the backrest of the car seat, and can be adjusted up and down. The headrest includes the middle pillow b1, and the left wing that is independently located on the left and right sides of the pillow b1 and extends toward the front of the headrest b2 and the right wing part b3, the left and right wing parts b2 and b3 are provided with cavities for embedding sound boxes, the central axes of the left and right loudspeakers b4 and b4-1 in the sound boxes are respectively connected to the central axis of the headrest The intersecting angle is γ, γ=60°~120° angle. In this embodiment, γ=100° is selected, and the intersecti...

Abstract

The invention discloses an independent sound system of an automobile seat. The independent sound system comprises a headrest, sound boxes, a power amplifier and a sound source, wherein the power amplifier is correspondingly connected with the sound boxes and the sound source in a signal mode. The headrest comprises an intermediate pillow portion, and wing portions on the left and right sides of the pillow portion extending toward the front of the headrest, wherein a cavity for embedding each sound box is formed in each wing portion, and a central axis of each loudspeaker in each sound box anda central axis of the headrest form an angle of 60-120 degrees. According to the independent sound system of the automobile seat, the sound boxes are arranged at the left and right wing parts of the headrest close to a head of a driver/passenger, so that the left and right loudspeakers face and are close to the left and right ears of a person in a small range and a short distance to form a stereofield effect of 'open headphones' near field listening. At the same time, the independent sound boxes of other seats in the same automobile can be prevented from influencing each other, the pressure caused by wearing earphones is avoided, and the ' in-head effect' of earphones cannot be formed.

Description

technical field [0001] The invention relates to the technical field of car audio equipment, in particular to an independent car seat audio system. Background technique [0002] Existing family cars are generally equipped with a sound power amplifier system, which cooperates with other functional modules in the car to realize the functions of listening to radio programs, playing music, and even answering mobile phones. If the driver wears headphones while driving, it is more dangerous and will affect his judgment on the surrounding environment of the car. Therefore, the audio system of most cars mainly includes the car audio of the original car. [0003] The earphone is a kind of near-field listening equipment, that is, the earphone diaphragm is close to the ear to listen to music, which makes the attenuation of the sound wave transmission in the air medium almost zero, so its attenuation and distortion in the air medium are very small. So this way of listening to audio is t...
